The unique design of the Supercaliber eliminates traditional suspension hardware, resulting in reduced weight, lower maintenance and decreased lateral flex. IsoStrut connects the mainframe to the pivotless seat stays, providing approximately 80 mm of rear wheel travel. This design offers a unique blend of efficiency, traction and fatigue-fighting compliance, maintaining control and freshness for riders.

IsoStrut integrated suspension gives you just enough travel to stay in control. It's fully tunable like a standard rear shock, but without the weight penalty of a full suspension bike.



SLR OCLV Mountain Carbon ensures a featherweight frame as a result of its high modulous carbon fibre lay-up, saving weight by utilising less material and skipping internal guide tubes for cable routing.

Please note, this bike does not come with pedals. We recommend selecting your own to ensure the best possible ride, please check our pedal guide for recommendations best suited to your riding style. For ultimate racing efficiency, we recommend clipless MTB pedals.
