Trek Supercaliber SLR Gen 2 Frameset

Supercaliber SLR Frameset is an ultra-light cross-country race frame that's ready for your dream build. It starts with a high-mod OCLV Mountain Carbon frame with 80mm of IsoStrut rear suspension that smooths out the rough with minimal interference on pedaling efficiency. Its geometry is optimized for a 110mm fork and whatever components your heart desires.

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 80mm 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 tuneable 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 fiber layup that allows us to use less material, plus we skip internal guide tubes for cable routing, minimizing material and maximizing weight savings.
