We've known for years that smoother is indeed faster, but until the S-Works Ruby with Shimano Dura-Ace Di2 came along, we had no idea just how right we were.
The frame is among the lightest that we've ever made, and it's been constructed from our top-end 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 advanced, dedicated engineering, however, we've managed to keep the same fit, feel, and position that we've all come to love from the SL4's Women's Endurance Geometry.
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 Ruby outperforms anything on the market.
Lastly, we spec'd it with awesome components that'll make your friends overcome with envy, like Shimano's legendary Dura-Ace Di2 shifting and hydraulic disc brakes, hand-built Roval CLX 32 Disc wheels, and a whole host of women's-specific features, from the handlebar width to the saddle.
