The Trek Madone SLR 7 Gen 8 is built for serious road cyclists who want a bike that blends race-ready speed, refined comfort and cutting-edge integration. Trek’s premium 900 Series OCLV Carbon frame forms the heart of this performance machine. Engineered with Full System Foil tube shaping, it slices through the air with remarkable efficiency, improving aerodynamics across the entire rider and bike system.
New to this generation is IsoFlow seat tube technology, a feature that increases compliance at the saddle without compromising aerodynamic performance or frame stiffness. It helps reduce fatigue on long rides while maintaining the snappy, direct feel racers demand.
Shifting is handled by Shimano Ultegra Di2 R8170, a 12-speed wireless electronic system known for its precise and consistent performance. You’ll enjoy fast, effortless gear changes even under load, with programmable controls to tailor your shifting to your style. The 52/36 chainset and 11-30 cassette offer the perfect balance of race-ready gearing and climbing capability.
The Shimano Ultegra hydraulic disc brakes paired with CentreLock 160mm rotors deliver confident stopping power in all conditions, while Bontrager Aeolus Pro 51 carbon wheels provide a light yet stable platform for high-speed racing and aggressive cornering. Wrapped in Pirelli P Zero Race 700x28mm tyres, they offer superb grip, low rolling resistance and a supple ride feel.
The Trek Aero RSL integrated bar and stem not only enhances the bike’s aerodynamic profile but also gives you a clean, race-focused cockpit. Added extras like the RSL Aero Bottles and Cages further reduce drag while offering practical hydration storage. With full internal routing, electronic-only compatibility, and a T47 bottom bracket, this bike is engineered for performance and ease of maintenance.
If you want an aero road bike that’s responsive, comfortable, and fully equipped for elite-level riding, the Madone SLR 7 Gen 8 delivers everything you need to take your racing and road cycling to the next level.
