Specialized Roubaix Sport 105 Disc Road Bike 2020
The Specialized Roubaix Sport 105 Disc Road Bike is ready for whatever you can throw at it. From cobbles to smooth tarmac, this performance road bike excels. Built on a FACT 10r carbon fibre frameset, power transfer is excellent, while the lightweight FreeFoil aerodynamic tubes make the frameset more aero than Specialized's Tarmac and lighter than the Venge.
A Future Shock 1.5 front suspension system damps vibrations from the road over the 20mm of travel. Top and bottom end bumpers ensure quiet and smooth operation and the tension can be altered by swapping out the spring. The S-Works Pave seatpost incorporates a lot of compliance into the aerodynamic D-shaped profile, leaving a clean looking aesthetic. The drop-clamp design bolts the post in place inside the frame, so there's more of the post free to deflect.
Shimano's 105 R7000 groupset is arguably the best value option available, with plenty of the features of its flagship Dura-Ace components trickling down to deliver serious shifting and braking performances. The Praxis Alba crankset has a compact chainring configuration making it perfect for steep hills. Your adventurous side will appreciate the quality DT Swiss R470 wheels, with a wide aluminium rim for comfort and reliability. In fact, the frameset has clearance for 33mm tyres, opening a whole host of mixed surface possibilities.
