The S-Works Roubaix SL4 builds on the standard Specialized model
and ramps up the performance to pro levels. The stiff FACT carbo
frame is tempered with Zertz dampers to suck up the road chatter, a
plus for cobbles. The Roval Rapide CLX 40 carbon wheelset with
CeramicSpeed bearings are fast and versatile.
This model was built with Ultegra Di2 and 785 hydraulic discs,
great performance at a really affordable price.
