When youre rolling smoother youre rolling faster. & regardless of if youre on the cobbles of Northern France or the chip & seal of your hometown youll benefit immensely from the Roubaix Comp. The super-light frame has been constructed from our FACT 10r 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 &34;get on to the suspension thing up front.&34; 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. Lastly we specd it with awesome components like Ultegra 8000 11-speed mechanical shifting 8020 hydraulic disc brakes & ultra-tough Roval SLX 24 wheels that have been cased in our Turbo Pro 28mm tires. 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 FACT 10r frameset holds its own with our high-end carbon offerings with the ideal blend of light overall weight & targeted stiffness while the all-new Future Shock &34;suspension&34; system at the cockpit delivers a revolutionary degree of comfort & control. A Roubaix Disc fork is built from our FACT carbon fibre for supreme stiffness strength & reactivity while a thru-axle design only stands to bolster all of the above. The Roval SLX 24 Disc wheelset features a sub-1600-gram weight a 20-millimeter internal width & an alloy construction that makes it a solid performer for any cross event.FRAMESpecialized FACT 10r carbon Endurance Geometry Rider-First Engineered 12x 142mm thru-axle Future Shock suspension 20mm of travel flat disc mounts FORKSpecialized FACT carbon 12x 100mm thru-axle FRONT WHEELRoval SLX 24 Disc sealed cartridge hubs DT Swiss Competition spokes 24h REAR WHEELRoval SLX 24 Disc sealed cartridge hubs DT Swiss Competition spokes 24h INNER TUBESStandard Presta valve FRONT TYRETurbo Pro 60 TPI folding bead Black Belt protection 700x 28mm REAR TYRETurbo Pro 60 TPI folding bead Black Belt protection 700x 28mm CRANKSETPraxis Zayante 6061 alloy chainrings alloy bolts CHAINRINGS50/34TBOTTOM BRACKETIncluded w/ crankset SHIFT LEVERSShimano Ultegra 8020 hydraulic disc FRONT DERAILLEURShimano Ultegra 8000 braze-on REAR DERAILLEURShimano Ultegra 8000 long cage 11-speed CASSETTEShimano 105 11-speed 11-32t CHAINKMC X11EL 11-speed w/ Missing LinkFRONT BRAKEShimano Ultegra 8020 hydraulic disc REAR BRAKEShimano Ultegra 8020 hydraulic disc HANDLEBARSSpecialized Comp Hover Bar 6061 alloy 70x 125mm w/ Di 2 hole TAPES-Wrap w/ Sticky gel STEMSpecialized 3D forged alloy 4-bolt 7-degree rise SADDLEBody Geometry Phenom Comp Adaptive Edge design Hollow Cr-Mo rails 143mm SEATPOSTSpecialized CG-R FACT carbon single-bolt 27.2mm PEDALSNylon 105x 78x 28mm loose balls w/ reflectors
