Trek Supercaliber 9.8 Gx Mountain Bike
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 60mm 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.
OCLV Mountain Carbon
Trek’s mountain-specific carbon is engineered to withstand the extreme demands of off-road racing. Advanced analysis allows our designers to create a frame with the best blend of light weight, responsiveness, and just enough compliance in the seat stays to eliminate the need for a heavy rear pivot system.
Straight Shot w/Knock Block
Trek’s Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You’ll be able to push harder and stay more planted on your line when the going gets rough.
