It's right for you if...

You're an experienced roadie who doesn't settle for anything less than a top-of-the-line drivetrain. You're used to long days in the saddle, but now you want to be even faster and more efficient, and you're ready to make the jump to a road bike with carbon wheels and hydraulic disc brakes for better control on rough roads.

The tech you get

A 500 Series OCLV Carbon frame with Front and Rear IsoSpeed, Bontrager Aeolus Pro Disc carbon wheels, powerful flat mount hydraulic disc brakes, wide 700x32 tires, and a full 2x11 Shimano Dura-Ace groupset. Domane SL 8 Disc also has internal cable routing for clean looks, a carbon seatmast, and a stable Endurance Geometry for comfort on the longest days and roughest roads.

The final word

Better shifting means better performance. Domane SL 8 Disc has the highest-end mechanical drivetrain available, plus Bontrager Aeolus Pro Disc carbon wheels, Front and Rear IsoSpeed, and a lightweight carbon frame.

Sizing & fit

The charts below show our 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. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
