About product
Cube Reaction SLX metalicgrey`n`black
What to you to to improve the ride of a great bike that already has great components? You install better brakes. The powerful, progressive Shimano XT hydraulic disc brakes on the Cube Reaction SLX not only help with safety, but also make for faster riding and more enjoyment. Combined with the smooth control of the RockShox Recon Silver air fork and the easy shifting and wide gear range of the Shimano XT 1x12 drivetrain, you're practically ready to go. Schwalbe Racing Ralph 2.25-inch tires—fast, smooth, and grippy—complete the package for exploring the trails.
Highlights:
Elegant aluminum frame with internally routed cables
Shimano XT 12-speed drivetrain for a wide gear range and precise shifting
Hydraulic Shimano disc brakes for reliable stopping power in all weather conditions
RockShox Judy Silver air suspension fork with remote lockout for easy adjustment and excellent damping
The Reaction's sleek looks are thanks to its Smooth Welded head tube and seat tube junctions. It incorporates a threaded bottom bracket and Internal Cable Routing, plus a flat disc mount that integrates seamlessly with the kickstand mount and integrated mounting points for ACID mudguards and carrier. Trail-ready geometry includes a lower top tube and tapered head tube for more confident handling, and there's plenty of room to run wide, grippy and comfortable 2.25in tyres. And, as your skills increase, there's scope to fit a dropper post upgrade.
