The more comfortable you are, the faster you'll go. And if you need proof of this, look no further than Specialized's Ruby Pro Ultegra Di2. Its revolutionary design erases any shadow of a doubt that smoother is indeed faster. The frame is among the lightest that they've ever made, and it's been constructed from their superlative FACT 10r carbon fiber. Its stiffness levels are also off the charts and you'll experience fast, efficient geometry. Paired to the frame is a Ruby Disc fork that is built from extraordinary FACT carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above. On top of that, the fork features a suspension feature, Future Shock, a piston in the head tube with 20mm of travel. Specialized 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. Rolling beneath you are featherweight Roval CL 32 Disc wheels that provide the perfect balance of weight and aerodynamics. Shimano Ultegra Di2 shifting offers 11 speeds of electronic wonderment. Shifts are as precise as it gets, dropping chains becomes a rarity, and the trim adjust up front ensures that chain rub is a thing of the past—no matter how extreme your cross-chaining gets. Lastly, they spec'd it with awesome components, like Shimano hydraulic disc brakes, a plush CG-R seatpost and a women's-specific Ruby saddle.
