Cube Reaction SLX Mountain Bike in Metallic Grey/Black

Season:2026

Brand:Cube

Code:143200METICGRY

The Reaction SLX's Shimano XT hydraulic disc brakes offer powerful, progressive control for a safer and more enjoyable ride.

Combined with the smooth control of the RockShox Recon Silver air fork and the easy shifting and huge range of the Shimano XT 1x12 gears, this bike is well-equipped. The Schwalbe Racing Ralph 5.7cm (2.25") tyres – fast-rolling, smooth, and grippy – complete the trail exploring 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 the bike's 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.
