Specialized S-works Roubaix Mclaren Dura-ace Di2 Road Bike  2018 

Product ID: 74484

When you hear McLaren the first thing that comes to mind are its F1 race machines but thats not the only race machine that McLaren has their hands in. The S-Works Roubaix McLaren with Shimano Di2 has been designed in tandem with McLaren Applied Technologies. To celebrate this this limited edition model features a one-of-a-kind paint job custom hubs and custom bar tape. So you wont only be riding the most comfortable race-bike out there youll be on the coolest one too.

The frame is one of the lightest that weve ever made and its been constructed from our top-tier FACT 11r carbon fibre. Its stiffness levels are also off the charts and compared to the SL4 iteration of yesteryear youll experience a whole new faster and more efficient geometry. Through some engineering sorcery however weve managed to keep the same fit feel and position that weve all come to love from the SL4 and kept it consistent throughout the size-range due to our Rider-First Engineered™ construction.

Of course youre probably thinking get on to the suspension thing up front. We call it Future Shock and essentially its a piston in the head tube with 20mm of travel. We developed this technology in partnership with McLaren Applied Technologies and 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 and comfort in one fell swoop. And of all the bikes that weve tested with our Rolling Efficiency Model the new Roubaix outperforms anything on the market.

To add to the pizazz of this custom build we specd it with Shimanos benchmark Dura-Ace 9150 Di2 groupset S-Works carbon bits and hand-built Roval CLX 32 Disc wheels with custom hubs.
