The frame is among the lightest that Specialized have ever made and it's been constructed from a 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. The same fit, feel and position that we've all come to love from the SL4's Women's Endurance Geometry has been maintained.
The Future Shock suspension is essentially a piston in the head tube with 20mm of travel. This technology was developed in partnership with McLaren Applied Technologies and the result of this are a host of drastic performance improvements namely in the vertical compliance department. Focusing on vertical compliance instead of fork splay meant that smoothness, speed and comfort could be improved in one fell swoop. Of all the bikes tested with the Rolling Efficiency Model, the new Ruby outperforms anything on the market.
It is spec'd with an awesome set of components that are hand-selected to endure harsh roads. Along these lines, you'll find the Expert outfitted with the likes of Shimano Ultegra 8000 mechanical shifting, powerful 8020 hydraulic disc brakes, low profile Roval SLX 24 wheels and a host of women's-specific components.
