The frame is among the lightest that Specialized have ever made, and it's been constructed from a superlative FACT 9r carbon fibre. Its stiffness levels are also off the charts, and compared to the previous SL4, you'll experience a whole new, faster, and more efficient geometry. Through some advanced, dedicated engineering, however, the same fit, feel, and position that we've all come to love from the SL4's Women's Endurance Geometry has been kept.
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 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.
Lastly, it is spec'd with a host of components that blur the lines between steadfast reliability and outright performance, like a mix of Shimano 105 and Tiagra shifting, powerful hydraulic disc brakes, durable DT R470 Disc wheels, and a women's-specific saddle.
