Supercaliber SLR Frameset is an ultra-light cross-country race frame ready for your dream build. Its high-mod OCLV Mountain Carbon frame features 80mm of IsoStrut rear suspension to smooth rough terrain without sacrificing pedaling efficiency. It's optimized for a 110mm fork and ready to be built into a fast, race-ready machine.
Nothing else like it
Supercaliber's unique frame design ditches traditional suspension hardware so there's less weight, less maintenance and less lateral flex. IsoStrut connects the mainframe to the pivot-less seat stays to offer about 80 mm of rear wheel travel. This design offers a unique blend of efficiency, traction and fatigue-fighting compliance that keeps racers fresh and in control.
IsoStrut
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
Supercaliber SLR is the World Cup lightweight frame. It drops grams by using a higher modulous carbon fibre lay-up that allows us to use less material, plus we skip internal guide tubes for cable routing, minimising material and maximising weight savings.
