2018 S-Works Roubaix McLaren Dura-Ace Di2

When you hear "McLaren," the first thing that comes to mind are its F1 race machines, but that's 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 won't only be riding the most comfortable race-bike out there, you'll be on the coolest one, too.

The frame is one of the lightest that we've ever made, and it's been constructed from our top-tier FACT 11r carbon fiber. 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. Through some engineering sorcery, however, we've managed to keep the same fit, feel, and position that we've all come to love from the SL4, and kept it consistent throughout the size-range due to our Rider-First Engineered™ construction.

Of course, you're probably thinking, "get on to the suspension thing up front." We call it Future Shock, and essentially, it's 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 we've tested with our Rolling Efficiency Model, the new Roubaix outperforms anything on the market.

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

• Featuring our Rider-First Engineered™ design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Roubaix. The S-Works FACT 11r frameset is our highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness, while the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.

• An S-Works FACT Disc fork is built from our FACT carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.

• A 52/36T S-Works carbon fiber crankset delivers the ultimate in power delivery, with a chainring grouping that's equally suited to big alpine climbs as it is to throwing down the gauntlet on the flats.
