The smooth advantage
Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger for 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 tyre clearance
Comes equipped with fast-rolling 32 mm tyres, but offers clearance for up to 38 mm tyres so you can confidently ride everything from smooth tarmac 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.
Shimano Ultegra Di2
Ultegra Di2 R8100 is Shimano’s most inspired drivetrain, packed with innovative, game-changing features. HYPERGLIDE+ technology allows for crisp, seamless shifts both up and down the gear range, even during maximal efforts. The new Di2 shifting system introduces Shimano’s exclusive wireless integrated circuit and the move to a 12-speed cassette ensures you have all the gearing you need. Ergonomics and aerodynamics have been enhanced at every turn and you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend flats for versatility or clipless pedals for control and efficiency.
