The perfect entry to our aero bike range. The REACTO 4000 uses exactly the same super-aero frame shape as our top level models, but by combining our lightweight CF3 carbon frame with high-value components, we've created a bike with performance that puts more expensive machines to shame. Using the utterly reliable Shimano 105 groupset with hydraulic disc brakes and some choice components, it's ready to ride and race from the box, as well as being a great platform to upgrade as you progress.

The thrill of speed is what unites road cyclists. Whether professional or amateur, the fundamental goal is to push harder, chase speed and break free. Nothing embodies this better than the REACTO. The latest generation of the REACTO builds on the previous model, with fundamental changes that further improve its aerodynamics, reduce its weight and offer tyre clearance up to 32 mm, all while maintaining the comfort and control the REACTO is known for. While the REACTO ONE substantially undercuts the 200-watt barrier as measured according to Tour Magazine's test standards and sets a new internal benchmark for aerodynamic performance, other bikes in the range offer the perfect balance between aerodynamics, comfort and control. Whatever your focus — low drag, low weight, or all-round performance — you will find the perfect REACTO in our latest line-up.
