Trek Madone SL 6 Disc Road Bike 2020
The Trek Madone SL 6 Disc Road Bike is the ultimate race machine that offers the versatility to add aero extension for triathlons and TTs. IsoSpeed in the Top Tube is adjustable so you can dial in the perfect amount of compliance and the rebound is damped so it's smooth and stable. This is a bike engineered for speed: The Kammtail Virtual Foil (KVF) tube shapes are wind tunnel developed and tested to be extremely aerodynamic. The fork also has KVF shaping with lightweight moulded carbon dropouts, while improved lateral stiffness makes handling ultra-precise. The Trek 500 Series OCLV carbon construction perfectly balances weight, strength and stiffness.
Shimano's Ultegra groupset has compact chainrings and a wide-ranging 11-28 cassette, supplying all the gears you'll need for spinning up steep climbs and hammering it down the other side. Shifting is smooth and precise, and with hydraulic disc brakes, you can be sure of the control and stopping power required for all-weather confidence. Bontrager's Aeolus Comp 5 Disc wheels have a deep 50mm rim that slices through the air yet remains stable in blustery conditions.
- 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 add 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
