All this adds up to a balanced, efficient and precise chassis that, in spite of its stiffness, wont beat you up thanks to the 27.2mm diameter seatpost. The bike features a superb Rock Shox Recon Silver suspension fork that delivers 100mm of supple travel to comfortably tame any trail. When it comes to drive Cube have really capitalized on the 2x concept by choosing a 2x11 Shimano XT drive group with sweeping 11-42 cassette and double chainset. Additionally, the hydraulic Magura MT4 disc brakes provided offer substantial stopping power in all conditions, while the smooth rolling Answer Atac AM wheelset paired with Schwalbe Rocket Ron/Racing Ralph tyres offer plenty of speed, grip and comfort. This trail-conquering package is finished with a stunning collection of Cube components. This includes a Cube Race EXC saddle to keep you comfortable, even on longer rides.

About Cube

Cube is a brand that has been experiencing continuous growth since their inception in 1993. In fact, expansion work at their HQ and production facility in Waldershof, Germany has been ongoing constantly for over 15 years. Cube even purchased their own construction company to reduce the costs associated with a 6-fold increase in size, German efficiency at its finest!

Cube’s success can be attributed to a mix of innovation, premium quality materials, state of the art technology and a Teutonic obsession with product testing. They take a highly technical approach to building bicycles, with each model being designed and tuned using CAD software before being transferred into aluminium, carbon fibre or titanium for extensive ride testing.
