Trek Madone SL 7 Disc Road Bike 2021
Developed in the wind tunnel, the Trek Madone SL 7 Disc Road Bike is seriously fast and aerodynamic, with Kammtail Virtual Foil (KVF) shaped tubes and a fork that minimises drag. An H1.5 fit, one developed in collaboration with professional teams, puts you in an aggressive position optimised for speed. Adjustable IsoSpeed technology has been included in the top tube so you can dial in your preferred compliance and benefit from the smoothing effect.
Rolling on 50mm deep Bontrager Aeolus Pro 5 wheels brings further aero benefits and the tubeless-ready construction means it's easy to convert and enjoy even more comfort, faster rolling and a reduced risk of punctures. Fast, reliable and smooth shifting performance comes from a Shimano Ultegra Di2 groupset. The combination of compact chainset and 11-28 cassette ensures you have a wide range of gears to make light of the climbs and allow you to put down all your power in the sprint too. A standard bar and stem combination means you'll get the aero performance of the Madone with the capability to add extensions for TT's, adding versatility.
- Trek 500 Series OCLV carbon that's light, strong and stiff, with KVF tube shapes
- KVF fork with aero legs to minimise drag, and moulded carbon dropouts to reduce weight
- H1.5 fit developed with professional teams to ensure the optimal aero race position
- Adjustable top tube IsoSpeed lets you adjust compliance to your preference, and it's damped with an elastomer so it rebounds in a smooth, controlled, stable motion
- All the aerodynamic advantages of the other road bike models but with a stem and aero handlebar setup for the capability to clip-on extensions for triathlons and time trials
- Disc brakes offer better braking performance and extra clearance for wider, more stable tyres
- Internal cable routing
- The Madone seatpost has an integrated mount for the Bontrager Flare RT tail light
- Blendr compatible stem
