S-WORKS RUBY DURA-ACE DI2 56CM - 2019
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.
- 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 Ruby. 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.
- Shimano's Dura-Ace group offers exceptionally crisp shifts, smooth brake modulation, and keeps the overall weight of this Ruby at an absolute minimum.
- The Roval CLX 32 wheelset is the perfect balance of light weight, durability, and aerodynamics. It's stiff enough for sprinting, strong enough for abuse, and its CeramicSpeed bearings keep things silky-smooth, making CLX 32 wheels the ultimate all-rounders.
