Trek Madone SL 6 Gen 8 Road Bike – 2025

£4,250.00

Trek Madone SL 6 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. It’s built to race with geometry that keeps you comfortable on the climbs and perched for the attack. A Shimano 105 Di2 electronic group set keeps the price down without sacrificing lightning-fast electronic shifting. Plus, it’s topped off with carbon wheels for extra lightweight performance.
