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. A fully integrated cockpit keeps your set-up looking as sleek as it feels and an easy-access storage compartment stows ride essentials. Pair that with road-smoothing rear IsoSpeed, easy-access internal storage, tubeless-ready wheels and you'll be riding for longer – and having more fun – than you ever thought possible.
It's right for you if...
Every ride might start on the road, but that doesn't mean it'll end there. You want a ride that balances versatility, comfort and speed. Looks are important, but so is reliability, and you love the high-tech electronic set-up of the Shimano 105 Di2 drivetrain and stopping power of hydraulic disc brakes. Finished off with a carbon frame and rear IsoSpeed, you know that every ride is going to be a dream.
The tech you get:
A light and refined 500 Series OCLV Carbon frame with road-smoothing rear IsoSpeed. A Shimano 105 Di2 2x12-speed electronic drivetrain and powerful flat-mount disc brakes. Plus, wide Bontrager Paradigm Comp 25 tubeless-ready wheels, internal storage and cable routing that add to the bike's capability and sleek look. An added top tube mounts let you secure bags for longer rides without bulky straps and bungees.
The final word:
All the road-smoothing benefits of a carbon Domane, with fully wireless Shimano 105 Di2 shifting. This bike is comfortable, fast, light and ready for adventure – with lofty 38 mm tyre clearance that keeps you floating on tarmac roads and light gravel alike.
