favorite_borderWhy you'll love it
- Supercaliber is a World Cup-worthy bike that’s quick, capable of soaring through techy terrain, and nearly as light as a hardtail
- Our exclusive IsoStrut shock provides tuneable, damped suspension for a smooth and efficient ride
- Pivotless seat stays save on weight and actively bend to help soak up trail chatter
- You'll never again have to wonder, "What's faster for this course, full suspension or hardtail?"
"2020 Mountain Bike of the Year"
Supercaliber earned top honors from BIKE Spain, whose editors said this innovative ride delivered "twice the highest performance" they'd ever tested.
"Does it deliver? Yes!"
"Locked out, Supercaliber climbs as well as a fully rigid bike, but with the fork and shock open, the bike has gobs of traction heading uphill and minimal pedal feedback in the suspension. Descending, it's much more sure-footed in technical terrain than a hardtail and feels like it has way more travel than it really does."Read more

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.
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.
Complete Tubeless System
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.
Water bottle capacity
Space for two water bottles makes it easier to stay hydrated on long days.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
