10 years ago, we launched a bike that kickstarted a revolution in the design and construction of the performance road bike. The Teammachine SLR has won every major title that a bike can win, including Monuments, World Championships, Olympic Games, and the Tour de France. Using the combined knowledge from the past decade, we've changed the game again to deliver an all-new, class-leading frameset ready to lead for another 10 years. ACCELERATED COMPOSITES EVOLUTION TECHNOLOGIE + (ACE+) - ACE+ not only runs through thousands of virtual prototypes using Stiffness, Weight, and Compliance as key influencers, but now includes a fourth key factor in the prototyping, Aerodynamics. INTEGRATED COCKPIT SYSTEM (ICS) - The aesthetic simplicity and innovative functionality of the Integrated Cockpit is the epitome of Swiss engineering and design. ICS keeps cables and housing in their place: out of sight. D-SHAPE SEAT POST - Improved seatpost design removing any excess materials, providing aerodynamic benefits and extra compliance. BOTTOM BRACKET AND TORSIONAL STIFFNESS - Renowned for its power transfer, the new Teammachine SLR goes one step further with a wider bottom bracket contact area provided by the new downtube shape and the optimized carbon layup. FORK PROFILE - An aerodynamically reshaped fork with stealth dropout design and integrated thru-axle nut show that high technical proficiency can go hand in hand with beautiful, minimalist aesthetics. AEROCORE DESIGN - Our Aerocore system consists of two superlight carbon cages that seamlessly integrate into the reshaped downtube and seat tube, resulting in significant drag reduction when used with bottles. COMFORT IS SPEED - The new Teammachine SLR is more compliant than ever, thanks to the latest evolution of the Tuned Compliance Concept (TCC) technology. Fine-tuning of the carbon layups offers essential vertical frame and seatpost flex to improve traction and control, resulting in reduced muscle fatigue.

THE LIGHTEST AND MOST CAPABLE RACING BIKE Performance, technology, and style have always been cornerstones of cycling. We may not compete but we love the feel of a racing bike – an Orca that is light, fast, and beautiful. Professional athletes, weekend warriors, Strava hunters, and recreational riders all have similar aspirations – we love the machine as much as the lifestyle. ICR Internal Cable Routing is carefully routed along the best path under the stem and through the head tube, with no rub or rattle, and is optimized for both traditional and electronic shifting systems. HIDDEN CLAMP Orca's seat post clamp is smoothly integrated into the frame, decreasing the likelihood of contamination and increasing aerodynamics. Not to mention, it looks great too. SEATPOST CLAMP The sleek and secure clamp of the Orca seat post is a proprietary design that allows tilt adjustments to be made independently of the saddle fore-aft position. INTEGRATION Cables and brake hoses are routed directly inside the stem under an aero cover. A clever headset design and split stem spacers allow the cables to enter the frame while still permitting stem adjustment.
