Cube Reaction SLX 2027
The Reaction frame's elegantly sculpted lines and super-clean tube joints are part of its appeal, sure. But there's solid practicality there, too. For example, the Internal Cable Routing – which complements the tidy aesthetic – includes cable protection inside the head tube. The 30.9mm-diameter seat tube is ready to accept a remote dropper post. Mounting points at the rear are compatible with our Semi-Integrated Carrier 2.1 and ACID mudguards. A UDH and Boost thru-axle rear end with extra-large chainstay protector is built to be both tough and future-proof. And mounting points under the top tube make it simple to add a compatible ACID tool or other accessory. Form and function, perfectly combined.

TOUR MEETS TRAIL
What do you do to improve the ride of a great bike that already features great components? You fit better brakes. The Reaction SLX's Shimano XT hydraulic disc brakes' powerful, progressive control doesn't just help keep you safe, it also helps you ride faster and have more fun. Combined with the smooth control of the RockShox Recon Silver 32 air fork and easy shifting and huge range of the Shimano XT 1x12 gears, you're pretty much all set. The Schwalbe Racing Ralph 2.25in tyres – fast-rolling, smooth and grippy, and fitted to Newmen Performance 30 wheels – round out the complete trail exploring package.

DETAILS
For those times when you just want to concentrate on the ride, nothing beats a really great bike fitted with kit you can rely on. The Reaction SLX's geometry, handling and Shimano XT gears and hydraulic disc brakes are all designed to let you get on with the important part – having fun.

The Shimano XT 12-speed drivetrain combines an XT rear derailleur and shifter with a Shimano Deore 10-51T cassette and 32T crankset. This wide gear range makes it well suited to both fast riding and steep climbs.

The Reaction SLX uses a Schwalbe Racing Ray on the front and Racing Ralph on the rear, both with Addix Performance compound and Kevlar construction. This combination is designed to balance front-end grip with fast rolling at the rear.
