Cube Reaction Pro Mountain Bike In Old Grey/Black

Season:2026

Brand:Cube

Code:143100

The Reaction Pro is all about the ideal blend of function, reliability and performance.

This model began with the precision of Shimano's XT 1x12 gears, which offer an enormous range and an unparalleled reputation for accuracy. Shimano hydraulic disc brakes were added for their reliable all-weather stopping performance to help keep you safe, whether you're out in the hills or battling across town. It is finished with the RockShox Judy Silver air fork, which combines easy adjustability and a remote lockout with trail-smoothing alacrity. It's the complete package.

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 its 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 5.7cm (2.25") tyres. As your skills increase, there's scope to fit a dropper post upgrade.
