We always knew that smoother was faster but before the all-new Roubaix Expert we couldnt have imagined just how much faster it actually is. The frame is the lightest that weve ever made & its been constructed from our FACT 10r carbon fiber. 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. 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 6800 11-speed shifting hydraulic disc brakes & ultra-tough DT R460 Disc Pro wheels. 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 is exceptional in every way offering the ideal blend of light overall weight & targeted stiffness. Meanwhile 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 top-end FACT 11r carbon fibre for supreme stiffness strength & reactivity while a thru-axle design only stands to bolster all of the above. Shimano BR-805 hydraulic disc brakes deliver smooth modulation & lever feel & more importantly incredible stopping power in any condition.FRAMEFACT 10r carbon Endurance Geometry Rider-First Engineered™ 12x 142mm thru-axle Future Shock suspension 20mm of travel FORKRoubaix disc FACT 11r carbon 12x 100mm thru-axle FRONT WHEELDT R470 Disc Pro thru-axle 2 Bliss Ready REAR WHEELDT R470 Disc Pro thru-axle 2 Bliss Ready INNER TUBES700x 20/28mm 48mm Presta valve FRONT TYRETurbo Pro 700x 26mm 60TPI folding bead Black Belt protection REAR TYRETurbo Pro 700x 26mm 60TPI folding bead Black Belt protection CRANKSETShimano Ultegra Compact CHAINRINGS50/34TSHIFT LEVERSShimano ST-RS685 11-speed FRONT DERAILLEURShimano Ultegra braze-on REAR DERAILLEURShimano Ultegra long cage 11-speed CASSETTEShimano Ultegra 11-speed 11-32t CHAINShimano Ultegra 11-speed FRONT BRAKEShimano hydraulic Ice-Tech resin pads w/fins REAR BRAKEShimano Ultegra hydraulic resin pads w/fins HANDLEBARSSpecialized Hover Expert Alloy 15mm rise 125mm drop 75mm reach TAPES-Wrap Roubaix w/stickygel STEMSpecialized Pro SL alloy 4-bolt SADDLEPhenom Expert GT Adaptive Edge design hollow titanium rails 143mm SEATPOSTSpecialized CG-R FACT carbon single bolt 27.2mm
