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.
