Power over cobbles, potholes or smooth tarmac with speed and comfort on the Specialized Roubaix Comp Ultegra Di2 Disc Road Bike.

The FACT 10r carbon fibre frameset has been engineered to weigh less than the Venge and outperform the Tarmac in the wind tunnel. This is a seriously fast bike, with the added versatility of two key compliance features: Future Shock 1.5 front suspension and the S-Works Pave seat post. A Shimano Ultegra Di2 groupset adds electronic shifting to the equation along with powerful hydraulic disc brakes.

Specialized Roubaix Comp Ultegra Di2 Disc Road Bike

The Specialized Roubaix Comp Ultegra Di2 Disc brings a sense of adventure to the performance road bike platform. Built on a FACT 10r carbon fibre frameset, this is a seriously stiff, lightweight and aerodynamic platform that's ready to race. With the added benefit of compliance features and room for 33mm tyres, this bike has the versatility to match your sense of adventure.

The Future Shock 1.5 front suspension unit is a vast improvement on its predecessor, with top end and bottom end bumpers to soften and quieten impacts, even when unloaded. For cross-bike compliance, Specialized has engineered the superb S-Works Pave seatpost, which has a drop-clamp bolting mechanism to expose more of the post for maximum compliance.

Specced with a Shimano Ultegra Di2 groupset, you're getting instant electronic gear changes from highly reliable components. The RX805 rear derailleur features a clutch mechanism to ensure a smooth-running chain when you hit the cobbles or potholes. The R470 wheelset from DT Swiss is a lightweight aluminium option that boasts great reliability for the longest adventures on any road surface.
