Trek Domane SL 6 2025

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.
