Trek Madone SL 6 Gen 8 Road Bike 

The Madone SL 6 Gen 8 is a lightweight aero road bike packed with elite racing technology. Offering similar aero benefits to the Madone SLR Gen 8, it features an economical OCLV 500 Carbon lay-up and a two-piece cockpit with hidden cable routing.

Designed for racing, its geometry keeps you comfortable on climbs and poised for attack. Equipped with a 2x12 Shimano 105 Di2 electronic group set, it ensures lightning-fast electronic shifting, complemented by Bontrager Aeolus Elite 35 carbon wheels set up tubeless for extra lightweight performance. Ideal for those seeking a featherweight road race bike, it's perfect for racing, club rides, or solo spins up winding canyons, balancing climbing efficiency and aerodynamics.

The Trek bike boasts Revolutionary Full System Foil aero tube shapes for optimized aerodynamics, a lightweight frame that excels on climbs, and the reliable Shimano Di2 group set. With lightweight, race-focused IsoFlow comfort technology, the Madone SL 6 Gen 8 helps you ride stronger and longer without sacrificing weight or aerodynamics.

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.
