Good condition approved used bike with some cosmetic scuffing to the levers and saddle, as well as paint damage on the fork and downtube
With advanced aerodynamics and svelte lines, the Trek Madone SL 6 Disc Road Bike provides style and performance in a race-ready package. The 500 Series OCLV Carbon construction is lightweight and stiff for unrivalled power transfer and features Kammtail Virtual Foil tube shapes to cut drag to a minimum. Adjustable top tube IsoSpeed allows the user to customise the level of compliance on offer, making this far more versatile than its aero tubeset would have you believe.
The tubeless-ready Aeolus Comp wheels feature a modern 18mm rim width with a deep profile to improve their aerodynamic performance. Bontrager R3 Hard-Case Lite tyres roll fast and use an aramid bead, and the Bontrager cockpit offers pinpoint control on the road. A full Shimano Ultegra groupset provides proven, crisp shifting across the wide 11-speed range, and hydraulic disc brakes offer ample stopping power to boost confidence on the descents.

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.

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.
