No matter where you ride, no road surface is perfect. That's why our Ruby Expert with Ultegra Di2 focuses on providing next-level smoothness in a package that's tailor-made for women of all abilities. The frame is among the lightest that we've ever made, and it's been constructed from our superlative FACT 10r carbon fibre. 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, hydraulic disc brakes, and a women's-specific saddle.
- The FACT 10r frameset is exceptional in every way, offering the ideal blend of light overall weight and targeted stiffness. Meanwhile, the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.
- A Ruby Disc fork is built from our extraordinary FACT carbon fibre for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.
- 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.
- Comes equipped with a 25lbs spring installed (color: black, weight: medium), and also includes both 13lbs (color: blue, weight: soft) and 40lbs (color: yellow, weight: firm) springs that can be installed to match the terrain you're riding.
