The Smooth Advantage

Refined IsoSpeed technology absorbs fatiguing road vibrations and bumps while reducing overall weight, helping you stay stronger and more comfortable over longer rides.

Podium-Topping Speed

Proven on the cobblestones of Paris–Roubaix, the latest carbon Domane is faster than ever with improved aerodynamics and an ultra-lightweight design.

Lighter Than Ever

A redesigned 500 Series OCLV Carbon frame delivers an ideal balance of strength and low weight, making this the lightest Domane SL Disc yet.

Versatile Tyre Clearance

Supplied with fast-rolling 32 mm tyres and clearance for up to 38 mm tyres, giving you the flexibility to ride smooth tarmac, rough roads and light gravel with confidence.

Internal Storage

Integrated downtube storage and top tube bag mounts make it easy to carry ride essentials for long days in the saddle.

Refined Integration

A cleaner, more premium finish with hidden cables and a concealed seatpost clamp for improved aerodynamics and sleek aesthetics.

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
