With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Cube Reaction C:68X SLX Carbon Hardtail MTB 2027 in Mediterreneansea/Prizm

Season:2027

Code:1143600MEDITERRENEANSEA

The Cube Reaction C:68X SLX is built for serious cross-country speed. Its premium carbon frame combines exceptionally low weight with a race-focused specification, creating a rapid hardtail designed to accelerate quickly, climb efficiently and carry speed across demanding XC terrain.

Cube's C:68X® Monocoque Advanced Twin Mold frame features Boost spacing, full internal cable routing, UDH compatibility and provision for a dropper post. An adjustable-angle headset allows the handling to be fine-tuned, while the Fox 32 SC Float Factory fork provides 100mm of travel, Kashima-coated stanchions and handlebar-operated two-position remote control.

SRAM GX Eagle AXS Transmission delivers precise wireless 12-speed shifting, with an X0 Eagle Transmission 34T crankset and wide-range 10-52T cassette providing the gearing needed for steep climbs and high-speed race efforts. Magura MT8 Pro hydraulic disc brakes provide powerful control while keeping weight low.

Newmen Phase 30 Light/Light carbon wheels complete the race-ready build, paired with Schwalbe Racing Ray and Racing Ralph Super Race 2.35in tyres for a fast combination of front-end grip and rear-wheel speed. With a workbook-listed weight of just 9.9kg, the Reaction C:68X SLX is a seriously focused XC machine.
