Trek Domane SL 6 Gen 4 Shimano Di2 Road Bike 2025 in Lunar Silver

The Domane SL 6 is an endurance road bike that’s light, aerodynamic and built to take on long, rough miles in the saddle. With the huge advantage of an electronic Shimano 105 Di2 drivetrain and clearance for 38 mm tyres, the Domane SL 6 is ready to soar over cobbles and tarmac alike. A fully integrated cockpit keeps your set-up looking as sleek as it feels and an easy-access storage compartment stows ride essentials. Pair that with road-smoothing rear IsoSpeed, easy-access internal storage, tubeless-ready wheels and you’ll be riding for longer – and having more fun – than you ever thought possible.
