Road Bike Frames

Don’t get us wrong, we’re all for racing. Grand Tour top steps, Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this is what the Aethos lives for. Sure, it’s given nothing up to performance, and happens to be the lightest frame out there, but with no compromise to 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.

Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. After eight generations and over two decades of development, it’s more than the fastest Tarmac ever - it’s the world’s fastest race bike. Your legs up for it?

Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.

• AERO IN EVERYTHING: We’re putting aero where it matters - the leading edge - not just where it looks good. In the process we’ve created our most aerodynamic road bike ever. Yes, it’s more aero than the Venge. Clean air is optimized for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer. By moving the steer tube back - the tube that determines head tube width - the leading edge of the head tube can be much sharper, delivering a much lower drag shape. Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made ensuring fast moving, dirty air around the legs can flow back more cleanly. Doesn’t victory smell sweet?
• MINIMUM WEIGHT, MAXIMUM AERO: Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than anything on else on the World Tour*. With the ability to make lightweight a top priority in the down tube, seat tube, and rear of the bike lessons from Aethos were applied. The frame’s shape carries load so efficiently that extra carbon stiffness layers become redundant. *Unless of course you count the time Kasper Asgreen raced our 585 gram Aethos frame during a Tour stage.
• GOES LIKE HELL, RIDES LIKE HEAVEN: With massive gains in stiffness-to-weight - an improvement of 33% over the SL7 - the Tarmac SL8 takes legendary handling, aggressive responsiveness and World Championship proven geometry to the next level. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort. Thanks to our Rider-First Engineering, every rider, regardless of size, gets the same unprecedented ride quality and handling. In the saddle the Tarmac SL8 delivers 6% more compliance, floating over rough road with a supple feel unique in the high strung world of race bikes. Tarmac’s proven geometry and 32mm tire clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tires when needed.
• BEYOND GENDER: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialize and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next level advantage of Tarmac SL8. It’s time to go Beyond Gender.
• 68mm threaded bottom bracket, flat mount disc brakes, and no-hassle seamless integration — the S-Works Tarmac SL8 Frameset is the ultimate starting point for your dream build.

We created the all-new Allez Sprint by cannibalizing the Tarmac SL7. We tore the Tarmac apart, and rebuilt it from alloy with our Smartweld technology. We leveraged every innovation and insight learned during its development to create the all-new Allez Sprint. Whether chasing a National title or attacking your buddies 15 minutes into an “easy” Sunday spin, we won’t be offended if you mistake the Allez for a Tarmac SL7. Some may call it a carbon copy, we call it the World’s First Alloy Super Bike

Ready to make your dream alloy super bike a reality? Start with the all-new Allez Sprint Frameset. Equipped with a Tarmac SL7 FACT carbon fork and seatpost, it’s compatible with both aero and traditional stems and bars, electronic and mechanical drivetrains, and features a no-fuss threaded bottom bracket. The rest is up to you.

• The Allez Sprint is the fastest alloy road bike in history, thanks to the time its sibling, the Tarmac SL7, spent in the wind. It’s details like the most complex alloy head tube we’ve ever made and integrated cables that make it 41 seconds faster over 40km than the previous Allez Sprint. That’s a hell of a facelift. With 41 seconds, you’d have a podium picture in your Insta feed, just saying.
• Whether you’re launching a sprint out of the final corner or attacking from the gun like a young Italian at the Giro, the Allez Sprint, with its one-piece bottom bracket and downtube, delivers the ruthless efficiency of alloy with unprecedented stability. By balancing power at the pedals with input at the bars, the Allez Sprint keeps you fast and confident on the limit.
• Dive for the winning gap, bang elbows in the final meters, dissect the most technical descents, all without feeling like you’ve gone ten rounds with the heavyweight champ. Dropped seat stays, and the Tarmac SL7’s carbon seat post and fork make the Allez Sprint supple in the saddle and precise at the bars—all with Tarmac SL7's World Championship-proven geometry. It’s as comfy as it is beautiful. Well, almost.
• One innovation over any other helps us deliver the new Allez Sprint’s aerodynamics, power transfer, and handling—Smartweld. Making the fastest bikes in the world out of carbon wasn’t hard enough. We hydroformed the bottom bracket and down tube from a single piece of alloy, built our most complex alloy head tube ever, and then put it all together with Smartweld. It’s what makes the Allez Sprint the first alloy super bike.

This is our RTP—Ready To Paint—colorway, allowing you to imagine the build, colors, and design of your dreams, then work with a custom painter to make it a reality.

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 Pavé seatpost controls that deflection for the optimal vertical compliance. Together they create AfterShock 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 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 828 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.
