Product Information

Specialized Roubaix Comp Ultegra Di2 Men's Road Bike

Up until now, British roads have been uncomfortable to ride on, not anymore. Introducing the Specialized, Roubaix range designed to battle with the toughest of surfaces whilst providing supreme comfort and stiffness at an optimal weight. This bikes comfort orientation makes it great for testing British roads in harsh winter conditions thanks to its Hydraulic disc brakes. Built with revolutionary future shock suspension found on the head tube, providing 20mm of travel, this design not only improves comfort but overall smoothness and speed thanks to a Specialized's partnership with McLaren Applied Technologies. Finally, this version of the Roubaix Comp has been finished with Ultegra Di2 that showcases the latest in electronic shifting and featuring smooth hydraulic braking technology. As well as this, the grade of carbon on the Comp has been upgraded to offer improved stiffness levels whilst reducing the Roubaix's overall weight. 

Full Specification



McLaren Applied Technologies Suspension

Of course, you're probably thinking, "get on to the suspension thing up front." Specialized call it Future Shock, and essentially, it's a piston in the head tube with 20mm of travel. They developed this technology in partnership with McLaren Applied Technologies, and the result of this is a host of drastic performance improvements, namely in the vertical compliance department. Without giving a physics lecture, Specialized found that focusing on vertical compliance, instead of fork splay, meant that they could improve smoothness, speed, and comfort in one fell swoop. And of all the bikes that Specialized have tested with their Rolling Efficiency Model, the Roubaix outperforms anything on the market.


The frame

The frame is among the lightest that Specialized have ever made, and it's been constructed from superlative FACT 10r carbon fibre. Its stiffness levels are also off the charts and compared to the SL4 iteration of yesteryear, you'll experience a whole new, faster, and more efficient geometry. 


The Components

Specialized spec'd the Comp Ultegra Di2 with an awesome set of components that are hand-selected to endure harsh roads. Along these lines, you'll find the Comp outfitted with the likes of Shimano Ultegra Di2 shifting and hydraulic disc brakes, low profile DT R470 Disc wheels, and a host of top of the range components.
