Trek Domane SL 6 Gen 4

Domane SL 6 is an endurance road bike thats light, aerodynamic, and built to take on rough roads and long miles in comfort. It has all the road-smoothing advantages of a lightweight 500 Series OCLV Carbon frame with rear IsoSpeed, a wireless electronic Shimano 105 Di2 drivetrain, and high-quality wheels. A fully integrated cockpit keeps your setup looking as sleek as it feels, and an easy-access storage compartment for stowing ride essentials.

The smooth advantage

Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger longer.

Podium-topping speed

Raced to victory on the infamous cobblestones of Paris-Roubaix, the new carbon Domane is faster than ever thanks to new aerodynamic improvements and an ultra-light design.

Lighter than ever

Light and strong 500 Series OCLV Carbon and a new gram-saving design make this the lightest Domane SL disc ever.

Versatile tire clearance

Comes equipped with fast rolling 32mm tires, but offers clearance for up to 38mm tires so you can confidently ride everything from smooth pavement to light gravel.

Internal storage

Internal downtube storage and top tube bag mounts make it easy to carry everything you need for all-day rides.

Refined integration

Domane is more integrated than ever, with hidden cables and a hidden seatpost clamp.
