Product Details

The Reaction SL hardtail mountain bike from Cube is light, agile and well equipped for off road fun.

The Reaction frame has been revamped for 2018 with a double butted 6061 aluminium giving low weight, better acceleration and control. Internal cable routing keeps things tidy. The superb Fox 32 Rhythm fork helps smooth out the trail ahead whilst also giving more grip and control for those tricky technical sections of trail.

A Shimano XT drivetrain offers durable reliable smooth shifting with a range of gears that can help you tackle any climb. All-weather, powerful Shimano hydraulic disc brakes provide ample stopping power and a combination of Schwalbe’s Tough Tom and Rapid Rob tyres give grip and control in a range of conditions.

A Cube finishing kit perfectly completes this bike making it ready to hit the mountains.
