At the heart of the Reaction C:62 SLX is Cube’s premium C:62 carbon frame, built using Advanced Twin Mold manufacturing. This process allows fine control over fibre placement, resulting in a frame that’s light, stiff and responsive where it needs to be, while remaining comfortable over longer rides. Agile Ride Geometry gives sharp, predictable handling that suits technical XC tracks and fast trail loops.
The Fox 32 Float Performance SC fork offers 100mm of controlled travel and a two-position remote lockout, letting you firm things up instantly for climbs or smooth sections. It keeps the front end precise without sacrificing comfort when the trail gets rougher.
SRAM’s GX Eagle Transmission brings wireless electronic shifting with excellent durability and consistency. The wide 10–52T cassette and 34T chainring give plenty of range for steep climbs and fast fire road efforts, with crisp shifts even under load.
Rolling on Newmen Beskar 30 wheels, the bike accelerates quickly and feels direct on the trail. Schwalbe Racing Ray up front and Racing Ralph at the rear offer a fast-rolling XC pairing with dependable grip in dry and mixed conditions.
Magura MT8 Pro brakes provide strong, controlled braking with a lightweight feel, helping you brake later and stay smooth through technical sections. With internal cable routing, dropper post compatibility and a wide size range from S to XXL, the Reaction C:62 SLX is a focused, race-ready hardtail that’s equally happy on start lines or all-day XC rides.

Ex-demo bikes are dealer test units: bikes that were ridden a handful of times by customers on demo days or short test rides, then sold off when the dealer rotates stock. They’re prepped by the shop’s mechanic before sale, often come with a shop warranty, and typically save 20-40% off the new RRP.
On Cyclesite, the ex-demo surface filters to listings in Excellent condition from business sellers (UK dealers and shops). Use the category filter to narrow by bike type, or browse all to see what’s available across the country.
FAQs
What is an ex-demo bike?
An ex-demo bike has been used by a dealer for customer test rides, demo days or staff training. Mileage is typically very low: under 100 miles in many cases. The bike is then sold at a discount to the new RRP, having been prepped and serviced by the dealer.
Are ex-demo bikes covered by a warranty?
Usually yes. Most dealers transfer the original manufacturer warranty (where the brand permits) or offer a shop warranty of their own. Always check the listing description and confirm warranty terms with the seller before paying.
How much do ex-demo bikes save vs new?
Typically 20-40% off the new RRP. The biggest savings come on premium models that have been on the floor for a season. Use the valuation tool to check fair market value for the same model in Excellent condition.
Why are dealers selling ex-demo bikes?
Dealers rotate demo stock at the end of each season to bring in next year’s models. Selling the ex-demo fleet recoups capital and clears space on the demo rack. It’s the same reason car dealers sell off ex-courtesy cars at a discount.
