Cube Reaction HPA SL 27.5 Hardtail Bike

The Reaction HPA SL's extraordinarily refined design combines maximum performance with the highest possible quality. The superb aluminium frame, in combination with top quality components such as the complete Shimano XT 2x11 group and the superlight FOX 32 Float suspension fork, makes it ideal for both XC races and multi-day alpine rides.

The 27.5" wheels offer exceptional handling while reducing rolling resistance.


The Reaction HPA (it stands for High Performance Aluminium) uses a triple butted 7005 aluminium frame manufactured with a complex, advanced hydroforming technique. Agile Ride Geometry blends uncompromising efficiency for forward propulsion with lively, playful handling.

Every detail has a function. The tapered head tube, X12 axle at the rear and the Press Fit bottom bracket shell all work together with the cross-ovalised down tube to provide optimum power transmission, precise steering and phenomenal acceleration. Slender seat stays and the 27.2mm diameter seat post give added comfort.


The FOX 32 Float suspension fork with remote lockout is a perfect fit for the frame's performance-orientated character. Shimano's XT disc brakes offer reliable stopping and the Shimano XT 2x11 transmission components are both high quality and versatile, thanks to the wide-ranging 11-42 cassette.

Fulcrum RED 44 system wheels with through axles front and rear accelerate rapidly whilst still being very stiff and strong. Lightweight Cube cockpit components combine peerless ergonomics with perfect control, finishing off this high performance package.
