Trek Madone SL 6 Disc Road Bike 2021
Comfortable, versatile, and most importantly fast, the Trek Madone SL 6 Disc Road Bike is a top choice for serious riders and racers. It's crammed with advanced technology, and constructed from a lightweight 500 Series OCLV Carbon frame and fork, creating lateral stiffness for incredibly sharp handling. Both use wind tunnel-tested KVF (Kammtail Virtual Foil) tubing that slices through the wind for a significant aero advantage.
Top tube IsoSpeed is responsible for the comfort of this bike. It's adjustable so you can fine-tune the compliance, while an elastomer damper ensures rebound is smooth and controlled.
The drivetrain is made up of 11-speed Shimano Ultegra, with disc brakes for powerful, reliable stopping, and a compact chainset is paired to an 11-30-tooth cassette bringing a wide range of gears. The stem, handlebar, cranks and seatpost are frame size-specific to optimise fit for every rider. If triathlons or time trials are your thing, you can clip on extensions for a more aerodynamic position.
The bike rolls on tubeless-ready Bontrager Aeolus Comp Disc wheels with a 50mm deep, aerodynamic profile. Bontrager R3 Hard-Case Lite tyres in a 25mm width are fast and smooth-rolling, but tyres up to 28mm can be fitted for further improved comfort.

All measurements in mm unless otherwise stated
The charts show Trek's recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike.
Should you have any specific questions, please contact us for information and talk to one of our experienced members of staff.

About Trek
The best bike, ridden everywhere.
Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.
Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
