The super-light frame has been constructed from a FACT 10r 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. The same fit, feel, and position that we've all come to love from the SL4 has been maintained, and it has been kept consistent throughout the size-range with a Rider-First Engineered™ construction.
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 Roubaix outperforms anything on the market.
This Roubaix Comp comes equipped Shimano's latest Ultegra 8050 Di2 shifting, hydraulic 8070 disc brakes, and alloy DT R470 Disc wheels.
