Coming fully equipped with the Future Shock a Ceramic Speed bottom bracket CG-R seatpost & a full SWAT™ box the S-Works Roubaix frameset is the perfect start to your cobble-crushing dream build. The frame is one of the lightest that weve ever made & its been constructed from our top-tier FACT 11r carbon fibre. Its stiffness levels are also off the charts & compared to the SL4 iteration of yesteryear youll experience a whole new faster & more efficient geometry. Through some engineering sorcery however weve managed to keep the same fit feel & position that weve all come to love from the SL4 & kept it consistent throughout the size-range due to our Rider-First Engineered™ construction. Of course youre probably thinking get on to the suspension thing up front. We call it Future Shock & essentially its a piston in the head tube with 20mm of travel. We developed this technology in partnership with McLaren Applied Technologies & the result of this are a host of drastic performance improvements namely in the vertical compliance department. Without giving a physics lecture we found that focusing on vertical compliance instead of fork splay meant that we could improve smoothness speed & comfort in one fell swoop. & of all the bikes that weve tested with our Rolling Efficiency Model the new Roubaix outperforms anything on the market. Featuring our Rider-First Engineered™ design that ensures every frame size has the same legendary responsiveness & smooth ride quality that youd expect from a Roubaix. The S-Works FACT 11r frameset is our highest quality carbon frame offering the ideal blend of light overall weight & targeted stiffness while the all-new Future Shock suspension system at the cockpit delivers a revolutionary degree of comfort & control. An S-Works Roubaix Disc fork is built from our top-end FACT 11r carbon fiber for supreme stiffness strength & reactivity while a thru-axle design only stands to bolster all of the above. FACT carbon CG-R seatpost has integrated elastomer inserts that help dissipate road chatter & vibration without sacrificing responsiveness or power transfer.FRAMES-Works FACT 11r carbon Endurance Geometry Rider-First Engineered™ 12x 142mm thru-axle Future Shock suspension 20mm of travel flat disc mounts FORKS-Works FACT carbon 12x 100mm thru-axle BOTTOM BRACKETOSBB Ceramic Speed bearings SEATPOSTSpecialized CG-R FACT carbon single-bolt 27.2mm
