Road Frames

With Future Shock suspension front and rear, the new Diverge STR delivers compliance without compromise. By suspending the rider—instead of the bike—Future Shock technology increases control and efficiency while decreasing fatigue, so you'll be riding farther and faster over chunkier terrain than you believed possible. The Diverge STR does this without the weight, sluggish pedal response, and inefficiency of other suspension systems. The S-Works Diverge STR starts with our FACT 11r carbon frameset with front and rear Future Shock suspension. - The new Diverge doesn't just have gorgeous lines, it has perfect curves too. Future Shock Rear puts 30mm of rear travel in the ideal path to smooth out rough roads. Its hydraulic damping controls travel to eliminate “bobbing" under power and ensure big hits never catapult you from the saddle, all without compromising fit or pedaling efficiency. - The S-Works Diverge STR FACT 11r carbon frame is more compliant than any drop bar bike we have ever made yet adds just 100 grams compared to the S-Works Diverge frame. Never have so few grams added so much capability. Climb it, race it, or load it down with bags and gear for the long haul—Diverge STR does it all faster and smoother without any excess baggage. - By suspending the rider with damped, tunable travel—20mm front/30mm rear—Future Shock Technology absorbs bump forces to boost your control and capability while retaining the efficiency and responsiveness of a rigid frame. Because as far as power transfer goes, it is a rigid frame. Power to the pedals makes the bike jump like a scared cat. You're efficient, you're comfortable, you're in control. Your bike is light, nimble, and responsive. - Born from decades of innovation and our Smoother is Faster philosophy, Future Shock was created to develop bikes that win on cobblestones, but it's found its purest expression on gravel. It's 20mm of adjustable, damped front travel that keeps you in control and on target, all while protecting your hands, arms, and shoulders from the battering. - More capability means more confidence, more confidence means more rides, more rides mean more fun, and it all starts at the contact patch. Nothing unlocks capability like tire clearance, and we're feeling generous. 47mm on a 700c wheel and 2.1" on 650B. Diverge STR is the most capable gravel bike we've ever made, so it's the most fun. We did the math.

We created the endurance road category two decades ago proving that high ergonomics means high performance. Today, the new Roubaix SL8 with Future Shock 3.0 is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence. The road may be hell below, but on Roubaix, it's always heaven above. - COMPLIANCE: Future Shock 3.0 is the star of the show, more tunable, adjustable, and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stiction-free travel between the stem and head tube. Future Shock helps keep your hands and bars steady for a smoother ride with more control to stay fast, safe, and confident. - Our dropped clamp design exposes more seatpost to increase deflection, but "more" isn't simply better. The Pave seatpost controls that deflection for the optimal vertical compliance. Together they create 'Cobble Gobbler' technology, and when paired with the Roubaix's rigid rear triangle, deliver a smooth ride with no loss in efficiency. - The Roubaix SL8 is the smoothest road bike our Ride Science Team has ever tested-reducing impacts at the bars and saddle by 53% vs. the nearest competition. With Roubaix's Future Shock 3.0 the wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. Typical forks deflect backward on impact, causing a measurable loss in speed. It's a scientific fact, smoother is indeed faster. - CAPABILITY: The Roubaix pioneered endurance geometry, so you ride "IN" the bike, not "ON" the bike to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it's ready to dissect a mountain decent at full gas. Snuggle up. - With tire clearance up to 38c/40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tire volume and traction comes with no downsides. - Roubaix inspires really BIG days on the bike, so we've given it every mount your adventures could need- three bottle mounts, top-tube mounts, and it's even fender-ready. So, go ahead and bring it all along for the ride. - PERFORMANCE: The new Roubaix SL8 is our most aero yet, with new aero shapes from our Free Foil library and dropped seat stays. At just 825 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos—the world's lightest production frame—and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter than the Roubaix.

The Otso Fenrir is a ride-anywhere bike for bike-packing races and afternoon adventures alike. It can be built with drop bars or with MTB bars and both selections are available as stock build options. A tire clearance of 29” x 2.6” or 27.5” x 2.8” keeps the Fenrir rolling on rough terrain, while the extra frame and fork braze-ons are ready to carry gear for days or weeks on the trail. Like all Otso bikes, the Fenrir has adjustable geometry via the patented Tuning Chip rear dropout system that makes the bike as adaptable as its rider. VERSATILITY While all Otso bikes are known for their versatility, the Fenrir might be the most versatile yet. It was designed to accommodate drop bars with a 50mm stem or MTB bars with an 80mm stem. It can be built with gears or single speed, with a suspension fork or rigid, with a mechanical or electronic drivetrain, or with a dropper or rigid seat post. The ability to fully customize the build of the bike makes the Fenrir as versatile as its rider. FENRIR WITH DROP BARS The Fenrir was designed with the option to be built with drop bars or MTB bars. When configured with drop bars, the Fenrir rides like an extra-capable gravel bike. The relatively longer top tube means a shorter stem is needed with drop bars to align with the rider's preferred reach. It can be built with standard road/CX/gravel bars for rides on local trails or with wider bars to fit a handlebar roll loaded with lots of gear. FENRIR WITH FLAT BARS When built with MTB bars, Fenrir rides like a 90s XC bike. It's fun and lively, yet efficient and Capable with a capital C. It can handle any sketchy descent or technical climb with ease. Because the top tube is relatively short for a mountain bike, a longer stem (80-90mm) is ideal for maintaining reach. Ride it on your local singletrack or load 'er up for that backcountry tour that you've been dreaming about--you know the one. However you choose to build it, Fenrir will ride any road/trail on the map and carry all the gear to get you there. DESIGNED FOR BIKE-PACKING Every last feature of Fenrir Ti is optimized for bike-packing. The titanium frame is strong, smooth, and lighter than steel. It can be built with flat bars or drop bars depending on your affinity for large handlebar rolls. Single-speed is an option for folks who like simplicity while touring. It has extra mounts on the frame and fork for hauling all the gear you'll need for days (or weeks) on the trail. The frame and fork can clear 29" x 2.6" or 27.5" x 2.8" tires for trails that are especially gnarly. No matter your destination and how long it takes to get there, Fenrir Ti is ready. SINGLE SPEED All metal Otso bikes have the option to be built single-speed or with gears. Fenrir is included in that group because it has a small notch on the rear dropout near the Tuning Chip. If you build your Fenrir with gears but want to convert to single-speed later on, there is a single-speed Tuning Chip ready to order alongside other accessories. There's no wrong way to build your Fenrir. SO MANY MOUNTS A bike-packing bike needs to be able to carry all the gear for days or weeks on the trail. Fenrir has mounts for bottles, fenders, and racks. The Enve fork also has three-pack mounts on either side for sharing the load. CAPABLE GEOMETRY Pick a trail on the map and ride it. Fenrir has the endurance of a gravel bike, with the stability of a mountain bike. Above all, it is Capable with a capital C so you can stay the course and reach your destination. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. AMPLE CLEARANCE Tires need to meet the demands of the trail for traction, stability, and comfort. Fenrir can ride up to 29" x 2.6" or 27.5" x 2.8" tires.

The Warakin Ti is an efficient, responsive, sprightly titanium bike that can handle any road in any weather. Using the progressive geometry of its Warakin Stainless predecessor, the Warakin Ti pairs unrivaled ride quality with the superior quality of titanium. It's a lightweight, durable, lively machine that will carry the rider to where they choose to go while enjoying every pedal stroke along the way. SUPERIOR TITANIUM The 3Al/2.5V B338 grade 9 titanium that we use for the Warakin Ti is the same titanium that has been a bicycle industry favorite for decades, and with good reason. Equal parts science and magic, titanium is durable, lightweight, lively, corrosion-resistant, and timeless. The tubing is seamless, butted, clean, and strong. It's because of the superior quality of titanium that we chose this material to lend to our heralded Warakin geometry as a bike that will endure the roughest roads in the harshest conditions and tell the stories for decades to come. EXTRA TIRE CLEARANCE If a bike is meant to ride any road in any condition, it needs to fit tires and wheels that will get you to and from your destination, while handling every bump along the way. The massive tire clearance of the Warakin Ti was built with this in mind. It'll fit 29" x 2.1" for that road that doesn't actually appear on the map, just as easily as 650b x 50mm for windy forest trails, or 700c x 35mm (or 700c x 50mm if you want a little extra) for your next gravel race. Because a frame that can last forever needs to have the ability to adapt to whatever the road (and the future) may bring. VERSATILITY Like all Otso bikes, the Warakin Ti sports our patented Tuning Chip rear dropout system, which allows the rider to lengthen or shorten the wheelbase by up to 20mm and raise or lower the bottom bracket by up to 4mm. For chunky gravel on remote roads, the longer wheelbase of the rear position is set for stability and comfort. For a quick spin around town or the CX course, the front position makes for snappy handling and agile control. The middle position? That's the best of both worlds. The Tuning Chip rear dropout system was designed because the bike should be just as versatile as its rider. TOP QUALITY Designed by the Otso engineering team, Warakin Ti frames are built by top fabricators in Taiwan and come with a five-year limited warranty. All bikes and frames are inspected and assembled at our headquarters in Minneapolis, MN USA. PROGRESSIVE GEOMETRY The progressive geometry of the Warakin Ti takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. EXTRA MOUNTING OPTIONS Numerous braze-ons accommodate three bottles, fenders, racks, cable routing clamps, frame bags, and more. Mix in the Wolf Tooth B-RAD System to even further increase on-bike storage options. SUSPENSION-READY The geometry of the Warakin Ti includes an axle-to-crown measurement of 420mm, which allows for a shorter suspension fork.

The heart of a light and versatile expedition bike, and the endpoint of our Hook platform. This titanium version retains the vigor of our hooligan tourer and distills it into a light and comfortable frame. Able to accommodate multiple-wheel sizes, along with myriad luggage configurations, it’s ready to be the centerpiece in any number of different builds. Paired with our light yet staunch full-carbon EXT V2 fork, this provides triple cage mounts, along with steadfast handling in rough conditions. HIGHLIGHTS: - Titanium 3Al-2.5V frame with T47 BB shell fender mounts and through axles. - Full carbon tapered fork with internal light cable routing, through axles and triple cage mounts. - Sram UDH derailleur hanger. - Toptube bag direct mounts, triple cage mounts on downtube and seattube for optimized bottle position, bottle cage mounts underneath the downtube, and rear rack mounts. - CNC yoke for maximum tire and chainring clearance. - Ovalized toptube for supreme steering precision and comfort. - Biaxially ovalized downtube for optimized power transfer and steering precision. - Front derailleur compatible. - 12 mm through axles front and rear.

The Aethos line promises three things—exceptional light weight, perfectly balanced ride characteristics, and undeniable style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride. And with this frame set, you have the perfect canvas to begin creating your dream ride. - The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, we've subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we've perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it's the first of a new breed. - A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we've developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you'll realize this sublime ride sets a new standard. - Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind—everything in pursuit for the perfect ride.

Voytek changes the fat bike game. It is fast, lightweight, agile, and can handle even the sharpest turns of your local singletrack with ease. Think of it as a mountain bike that can fit fat tires with adjustable geometry. We paired a narrow pedal stance—aka Q factor—with aggressive XC race geometry to build a fat bike that can intuitively handle snowy trails like your mountain bike can handle summer singletrack without sacrificing ride quality. When the weather turns and the snow turns to dirt, swap out the 26" fat wheelset for a 29" MTB wheelset to keep the party going all year. THE Q-FACTOR IS THE KEY The Voytek has the narrowest Q-factor of any fat bike in the world at 183mm. With a narrow Q-factor, your weight is closer to the centerline of the bike. This is especially important when cornering because it allows for tight, responsive control—the wider Q-factor found on most fat bikes spreads out your pedals and creates a floppy, unstable feel. The Voytek frame was designed around an 83mm bottom bracket, whereas most fat bikes have a bottom bracket north of the 100-110mm range. With the Voytek, you don't need to compromise agile handling to ride up to 4.6" tires. ONE BIKE, THREE WHEELBASE LENGTHS Our Tuning Chip rear dropout is at the heart of the versatile Voytek. With a quick change in positions, the wheelbase of the Voytek can be extended or shortened by up to 20mm, which also changes the bottom bracket height by up to 4mm and the head tube angle by +/.5º. In the forward position, you've got an aggressive, responsive Voytek for your next race. In the rear position, you've got that same intuitive handling but with added stability to make it easier to ride in deep snow or adverse terrain. In the middle, well, that's the best of both worlds. PLUS OR FAT? FAT OR PLUS? We're internally divided here as to whether the Voytek is a plus bike that can handle fat tires or if the Voytek is a fat bike that has the handling worthy of a plus bike. When the trails are packed with snow, we're riding 4" tires. When spring comes and the trails turn to dirt, we swap out tires and ride 29" plus until winter returns. The versatility of the Voytek blurs the lines of plus and fat, keeping the party going all year long. MODERN GEOMETRY Voytek's longer top tube, short chainstays – the shortest in the world for a fat bike – and slightly slacker head tube angle mean more speed and more fun. SUSPENSION CORRECT Voytek's suspension-corrected geometry is compatible with an Otso™ carbon rigid fork or up to 120 mm travel suspension fork. COMPETITOR TESTED, ISO APPROVED Voytek's patent-pending frame design exceeds all ISO frame safety standards and has been proven over thousands of miles of test riding, including the legendary Iditarod Invitational and Arrowhead 135 competitions. DROPPER COMPATIBLE The EPS molded carbon frame of the Voytek was designed to accept internally routed dropper seat posts.

The Waheela C is a carbon-framed drop bar bike with adjustable geometry, unrivaled ride quality, and enormous tire clearance for 700c x 54mm, 650b x 54mm, or 29" x 2.1" tires. It has extra frame and fork mounting points for bottles and racks, easily accessible internal cable routing options, compatibility for 1x or 2x electronic or mechanical drivetrains, and the ability to run a dropper post. No matter the road ahead (or under the tire), the Waheela C is ready. GIANT TIRE CLEARANCE Gravel comes in all shapes and sizes, from the packed limestone of Southeast Minnesota to the chunky roads of the Flint Hills of Kansas. The Waheela C is equipped with tire clearance to handle the terrain of your next race. Where most gravel bikes can fit 650b x 50mm but only 40mm with bigger wheels, the Waheela C keeps on rolling, with space for 700c x 54mm tires. It'll run 700c x 35mm when the roads are tacky and tidy, 700c x 42mm when there's a bit more uncertainty, 700c x 54mm when the gravel road turns to ATV trails, and anything in between. The Waheela C can also fit 29" x 2.1", 27.5" x 2.1", or 650b x 54mm if 700c isn't really your thing. In short, the Waheela C is ready for the road ahead. ADJUSTABLE GEOMETRY Like all Otso bikes, the Waheela C sports our patented Tuning Chip rear dropout system, which allows you to change the length of your wheelbase and the height of your bottom bracket. Put the Tuning Chip in the back position to get the stability and comfort of a longer wheelbase for a full day of riding gravel. Switch to the front position to get the agile handling and responsiveness required by your next CX race. And the middle position? That's the best of both worlds. The adjustable geometry of the Waheela C allows you to ride any road or any trail without needing to switch bikes. UNRIVALED RIDE QUALITY Our proprietary Waheela geometry was developed by our engineers for stability, confidence, and comfort on rough terrain. Where many gravel bikes put extra weight on the front wheel, the Waheela C centers the rider over both wheels. This makes for a more stable ride while allowing the compliant rear triangle to come into play and absorb the bumps of a gravel road. Meanwhile, the lightweight EPS molded carbon frame adds responsiveness and readiness for a sprint up that next hill. After a long day on the saddle, you'll find yourself adding a healthy amount of miles to tomorrow's ride. EXTRA MOUNTING POINTS Waheela C features fork bottle bosses, extra down tube mounting points (6 total), as well as top tube gas tank mounting points. Numerous braze-ons allow Waheela C to accommodate water bottles, fenders, racks, frame bags, and more. DETAILS THAT MATTER Internal brake and shifter routing with sleeves, carbon access door under the bottom bracket for easier routing, front and rear thru-axle, and threaded bottom bracket for reliable, easy service. This also allows you to run that dropper post you've been dreaming about. COMPATIBLE WITH 1X OR 2X Waheela C is 1x and 2x compatible with mechanical and electronic drivetrains. It's also fully compatible with both Shimano Di2 and SRAM eTap AXS, in case you don't want to take advantage of internal routing options. QUALITY ASSURED Designed by the Otso engineering team, Waheela C frames are manufactured in one of the premier carbon fiber factories in Taiwan and come with a 5-year limited warranty. All bikes are inspected and assembled at our headquarters in Minneapolis, MN USA.

Whether your goal is to escape on gravel back roads, far from cars and crowds, or drop the hammer at the front of your favorite gravel race, no bike does it better than the new Diverge. It's quite simply the fastest, most capable - and just maybe the most fun - bike we've ever made, delivering a ride that's quick and lively under power, but stable and confidence-inspiring when the terrain gets rough. From Future Shock 2.0 and all-new gravel geometry, to internal storage and category-leading tire clearance, the new Diverge represents everything we've learned over more than 40 years of riding road, gravel, and dirt. The Diverge writes an entirely new chapter in the gravel bike category, so you can dream up entirely new rides. It's the ultimate getaway vehicle. - With a FACT 9r carbon frame, the Diverge Comp frame is incredible capable and race bike light. Pin it for your local dirt climb KOM, or grind up a giant backcountry peak, the light and lively Diverge will get you there faster. - Speed, control and confidence - Future Shock 2.0 is the ultimate technology for the gravel rider. With 20mm of axial compliance and a hydraulic damper, Future Shock 2.0 suspends the rider not the bike. This keeps you confident and in control, able to keep the power down and stay off the brakes over rough dirt roads and in thick loose gravel, all while keeping your hands, arms and neck fresh. Since Future Shock 2.0's damper is adjustable, you'll be ready for the rough stuff and efficient on smooth pavement. - We tossed gravel geometry 'status quo' out the window. The new Diverge has the most progressive geometry we've ever created for a drop bar bike, giving riders a capable and stable bike in the dirt, that still feels responsive and nimble on the road. We've increased the frame's reach, introduced a slacker head tube and a longer offset fork. All this creates incredible confidence with a planted feeling in the dirt, while spec'ing shorter stems keeps the overall cockpit length the same and the steering lively. We've kept the bike's BB low to increase stability, but high enough to utilize with 650b wheels if that's your jam. - We've given the Diverge plenty of rack mounts, including fork and top tube mounts, to ensure you can take what you need, no matter how far you plan to go, or how long you plan to stay out. - Nothing unlocks a bike's capability like tire clearance, so we gave the new Diverge a whopping 47mm of tire clearance with a 700c wheel and 2.1" with a 650b wheel. Thanks to a drive side chain stay utilizing a solid beam of carbon behind the chain rings we've created clearance without using a fragile dropped chain stay design or increasing chain stay length.

Voytek changes the fat bike game. It is fast, lightweight, agile, and can handle even the sharpest turns of your local singletrack with ease. Think of it as a mountain bike that can fit fat tires with adjustable geometry. We paired a narrow pedal stance—aka Q factor—with aggressive XC race geometry to build a fat bike that can intuitively handle snowy trails like your mountain bike can handle summer singletrack without sacrificing ride quality. When the weather turns and the snow turns to dirt, swap out the 26" fat wheelset for a 29" MTB wheelset to keep the party going all year. THE Q-FACTOR IS THE KEY The Voytek has the narrowest Q-factor of any fat bike in the world at 183mm. With a narrow Q-factor, your weight is closer to the centerline of the bike. This is especially important when cornering because it allows for tight, responsive control—the wider Q-factor found on most fat bikes spreads out your pedals and creates a floppy, unstable feel. The Voytek frame was designed around an 83mm bottom bracket, whereas most fat bikes have a bottom bracket north of the 100-110mm range. With the Voytek, you don't need to compromise agile handling to ride up to 4.6" tires. ONE BIKE, THREE WHEELBASE LENGTHS Our Tuning Chip rear dropout is at the heart of the versatile Voytek. With a quick change in positions, the wheelbase of the Voytek can be extended or shortened by up to 20mm, which also changes the bottom bracket height by up to 4mm and the head tube angle by +/.5º. In the forward position, you've got an aggressive, responsive Voytek for your next race. In the rear position, you've got that same intuitive handling but with added stability to make it easier to ride in deep snow or adverse terrain. In the middle, well, that's the best of both worlds. PLUS OR FAT? FAT OR PLUS? We're internally divided here as to whether the Voytek is a plus bike that can handle fat tires or if the Voytek is a fat bike that has the handling worthy of a plus bike. When the trails are packed with snow, we're riding 4" tires. When spring comes and the trails turn to dirt, we swap out tires and ride 29" plus until winter returns. The versatility of the Voytek blurs the lines of plus and fat, keeping the party going all year long. MODERN GEOMETRY Voytek's longer top tube, short chainstays – the shortest in the world for a fat bike – and slightly slacker head tube angle mean more speed and more fun. SUSPENSION CORRECT Voytek's suspension-corrected geometry is compatible with an Otso™ carbon rigid fork or up to 120 mm travel suspension fork. COMPETITOR TESTED, ISO APPROVED Voytek's patent-pending frame design exceeds all ISO frame safety standards and has been proven over thousands of miles of test riding, including the legendary Iditarod Invitational and Arrowhead 135 competitions. DROPPER COMPATIBLE The EPS molded carbon frame of the Voytek was designed to accept internally routed dropper seat posts.

Our original all-road bike. The Warakin Stainless was one of the first bikes we built when we created Otso in 2016. It's been such a hit over the years that we haven't changed the geometry one bit. Stainless steel has a ride quality that is familiar, yet surprising—smooth like steel, lively like titanium. The Warakin Stainless is ready for your next century, three-day bike-packing trip, or afternoon group ride. STAINLESS STEEL The supple and smooth ride quality of steel meets the corrosion resistance and lively feel of titanium. Stainless steel is lighter than you think, loads of fun, and ready for your next full day on the saddle. It's a frame material that is as unique and seldom used as it is versatile and excellent for multiple types of riding. TIRE CLEARANCE 700c? Check! 650b? Double check! 29er? Triple check! Warakin Stainless has massive tire clearance because no two roads are the same. The Warakin Stainless has clearance for 700c x 51mm, 650b x 51mm, or 29" x 2.1" tires. Race gravel with 700c x 38mm semi-slicks, then swaps in 29" x 2.1" for that bike-packing trip with gnarly trails without needing to ride a different bike. TUNING CHIP™ The Tuning Chip rear dropout system allows for adjustable bike geometry by changing the wheelbase by up to 20mm, bottom bracket height by up to 4mm, and head tube angle by 0.2º. This means you can easily switch between a bike with the responsive, agile handling of a shorter wheelbase and a bike with the confidence and stability of a longer wheelbase just by flipping the Tuning Chip. Use the back position for stability and confidence with its longer wheelbase, lower bottom bracket, and slack head tube angle. The front position is ideal for winding singletrack or the CX course with its shorter wheelbase, higher bottom bracket, and steeper head tube angle. The center position is the best of both worlds. TOP PERFORMER Unparalleled ride quality results from the combination of stainless steel and carefully thought-out frame geometry. The Warakin Stainless was designed by our engineers in Minnesota and manufactured by top steel frame fabricators in Taiwan. PROGRESSIVE GEOMETRY Warakin’s progressive geometry takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. FOR THE LONG HAUL Numerous frame braze-ons allow Warakin to accommodate cable routing clamps, three water bottles, fenders, racks, frame bags, and more. Three braze-ons on either side of the fork allow for additional storage.

Steeped with more than 50 years of frame-building heritage, innovation, exploration, and lots of riding, the classic lines of this beautiful steel frame and carbon fiber fork unite with modern building techniques and proven materials to deliver a contemporary bicycle that’s wonderfully comfortable for long days in the saddle, nimble and stiff enough to win the sprint for that sign, and adequately adaptable to endure roads that might lack proper pavement. The Road Logic Disc frame is built with a heat-treated and triple-butted Ritchey Logic tubeset designed specifically for the Road Logic. It features aggressively short-butted sections optimized for TIG welding that save weight and improve ride quality.

The Road Logic offers a riding experience that's steeped with more than 50 years of life experiences, framebuilding heritage, innovation and exploration. The beauty of its classic lines unites with modern building techniques and proven materials to deliver a contemporary bicycle that's remarkably comfortable for long days in the saddle, nimble and stiff enough to win the sprint for that sign, and adequately adaptable to endure roads that might lack proper pavement. Tom Ritchey's framebuilding experience started in the 1970s when he built his first road frame in his parent's garage in northern California. Since then, Tom has continued to explore, experience and innovate in ways that define the craft. The Road Logic is the result of Tom's expanding legacy, his prodigious experience with steel, and mastery of the subtleties and details gleaned from his tenure in the art of creating bicycles. A true modern classic, Tom designed a heat-treated and triple-butted Ritchey Logic tubeset for the Road Logic, featuring aggressively short-butted sections optimized for TIG welding that save weight and improve ride quality. Ritchey’s proprietary forged-and-machined integrated headtube uses standard drop-in bearings and saves 80 grams over a standard head tube design. Wrapped in a delicious Sally’s Macarons coat of paint, the Road Logic also features spacing for up to 30c tires and a Ritchey Carbon Fork that will ensure a lifetime of enjoyable pedal turns. - Heat-treated, triple-butted Ritchey Logic tube set features short-butted sections optimized to save weight and improve ride quality - Painted to match Ritchey full carbon fork included - Forged and machined straight head tube - Standard road spacing on frame and fork - TIG welded - Fits tires up to 30c - Logic Zero WCS drop in 1-1/8" headset included

Big adventures require a bike that can rise to the occasion. Arctodus is named after Arctodus simus, an Ice Age behemoth that was the largest bear to ever walk the Earth. Like its namesake, Arctodus the bike is versatile, strong, and ready to explore. It has adjustable geometry, a durable steel frame, a massive front triangle for a frame bag, lots of cargo mounts, and can clear the biggest fat bike tires on the market. Arctodus is ready for afternoon exploration, polar expeditions, and everything in between. THE BIGGEST TIRE CLEARANCE Arctodus was built around a 26" x 4.8" tire for optimal handling and control on loose trails. It can fit the biggest fat bike tires in the world. The biggest fat tire on the market is 26" x 5.05" and Arctodus eats them like a snack with room to spare. Same as 27.5" x 4.5", which is the biggest 27.5" tire available. Arctodus is the only bike to clear tires this big with a 12-speed drivetrain without chain interference. When a bike is created for big rides with fresh snow, it needs to fit tires that were designed for the same reason. This is a bike that prays for snow and cuts its own trail. ONE BIKE, THREE WHEELBASE LENGTHS A key feature in all Otso bikes is adjustable geometry and the ability to adapt the bike for the ride ahead. The patented Tuning Chip rear dropout system can change wheelbase length by up to 20mm, raise or lower the bottom bracket height by up to 4mm, and change the head tube angle by +/.5º. Use the rear position when the trails are loose and you need as much control as you can get. Use the front position when the snow is firm and the trails let you take turns with a little speed. No matter the conditions, Arctodus has an answer. DESIGNED FOR EXPLORING There's no need to wait for the trail groomer. Arctodus was made for foot trails, forest paths, and snow-covered frozen lakes. The bombproof steel frame can withstand the demands of an expedition. A large front triangle can fit a healthy full-frame bag. The carbon fork has mounts on either side for cargo. A rear frame can be attached via mounts on the seat stays and Tuning Chip hardware. Even the geometry is catered for exploration, with extra trail for optimal flotation and bottom bracket height that will ride above deeper snow. Whether you're exploring local trails or a national forest, you can trust Arctodus to keep you riding. NARROW Q FACTOR Arctodus has a 100mm bottom bracket. This is 30-40mm narrower than other fat bikes that have the same tire clearance. Ride with massive tires without compromising handling. SUSPENSION CORRECT All Otso frames feature suspension-corrected geometry. Arctodus is compatible with suspension forks that have up to 120mm of travel. A few options are available on the Custom Bike Builder. STABILITY & FLOATATION Arctodus geometry was designed for optimal riding on fresh trails. The 68º head tube angle paired with massive tires gives Arctodus more trail than other fat bikes. Even the BB height was selected for clearance in deep snow. DROPPER COMPATIBLE Snowy trails are good with dropper posts, too. A port near the bottom bracket fits a cable and housing for a cable-actuated dropper post.
