The light weight frame has been constructed from our FACT 9r carbon fibre. Its stiffness levels are also off the charts & compared to the sl 4 iteration of yesteryear youll experience a whole new faster & more efficient geometry. Through some sophisticated engineering however weve managed to keep the same fit feel & position that weve all come to love from the sl 4 & kept it consistent throughout the size-range with 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 Roubaix outperforms anything on the market. Lastly we specd the Roubaix Sport with 105 11-speed mechanical shifting hassle-free Tektro Spyre mechanical disc brakes & DT r 470 disc wheels that have been cased in our turbo Pro 28mm tyres. Features 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 9r frameset holds its own with our highest-end carbon offerings, with 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. Dt r 470 disc wheels feature reliable, sealed cartridge hubs, & 24 front & rear spokes that keeps weight low & durability high. Shimano S 105 shifting & hydraulic disc brakes ensure reliable shifting & stopping power in a variety of conditions.
