The 2019 Specialized Roubaix Disc is a carbon endurance road bike with hydraulic disc brakes & Specializeds Future Shock headtube suspension system. The idea of a perfect road is a myth, as theres always a chip, a crack, a rough patch—you name it. But with the Roubaix, youll be taming wild tarmac without any extra effort. This is how road bikes were always meant to be. The super-light frame has been constructed from 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 sophisticated engineering, however, Specializedhavemanaged to keep the same fit, feel, & position that weve all come to love from the SL4, & kept it consistent throughout the size-range with their Rider-First Engineered™ construction. Of course, youre probably thinking, "get on to the suspension thing up front." They call it Future Shock, & essentially, its a piston in the head tube with 20mm of travel. Specialized developed this technology in partnership with McLaren Applied Technologies, & the result of this is a host of drastic performance improvements, namely in the vertical compliance department. Without giving a physics lecture, they 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. The base model Roubaix has 11-speed Tiagra shifting, RS hydraulic disc brakes, & DT R470 Disc wheels that have been cased in Turbo Pro 28mm tires, so there is nothing "base" about it. This Bike Is Perfect For The rider that wants a proven endurance road bike with the latest technology for the smoothest ride possible. The 2019 Roubaix is perfect for those long days in the saddle & sportive events. Key Features Tektro mechanical disc brakes take the hassles out of set up & maintenance, while still offering plenty of stopping power. Shimanos RS505 hydraulic disc brakes deliver plenty of stopping power & the superior modulation that hydraulic disc brakes are known for. With Shimano Tiagra taking the reins on shifting, youll experience crisp shifts for many miles to come.
