2018 Specialized Ruby Expert Di2

If you thought that a bike had to be jarring and unforgiving in order to be fast, we apologize in advance for bursting your bubble. The more comfortable you are, in fact, the faster you'll go. And if you need proof of this, look no further than our Ruby Expert with Ultegra Di2. Its revolutionary design erases any shadow of a doubt that smoother is indeed faster.

The frame is among the lightest that we've ever made, and it's been constructed from our superlative FACT 10r 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'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, like Shimano Ultegra Di2 shifting, 8070 hydraulic disc brakes, Roval SLX 24 Disc wheels, and a host of comfortable women's-specific components.
