|IsoStrut: an innovation in speed
The defining feature of this new category of race bike
is Trek’s exclusive IsoStrut shock—structural suspension
that pairs 60mm of damped, tunable travel
with unique pivotless seatstays that move with the trail
to keep you smooth and fast.
|The right travel for XC racing
We’ll come right out and say it:
you no longer have to choose between
a hardtail and full suspension bike on race day.
Supercaliber gives you just the right
amount of travel—60mm in the rear and 100mm in the front
to charge through the rough without losing speed
or traction, climb efficiently,
and put the hammer down in sprints.
|Lightweight trail performance
Every model has an OCLV Mountain Carbon frame
with Straight Shot down tube for extra stiffness,
Knock Block to prevent damage from spinning handlebars
or fork crowns, and Control Freak Cable Routing
to protect your cables and prevent them
from snagging on trail debris.
|Carry two bottles
Racing works up a thirst.
That’s why Supercaliber is built to carry two water bottles.
This bike gives you the suspension you need for demanding races,
plus the right storage for your fuel and water.
|Carbon wheels on every model
Every Supercaliber is equipped with lightweight,
trail-tough carbon wheels backed
by Bontrager’s Carbon Care Wheel Loyalty Program.
If you damage your carbon wheels within the first two years
of ownership, we’ll repair or replace them for free.
|Lightweight, structural speed
Standard full suspension bikes have an independent
shock and linkage system, but IsoStrut was designed
to be a structural part of Supercaliber.
This design eliminates the extra hardware
and parts normally associated
with full suspension bikes,
and the extra weight along with them.
IsoStrut is encased in a structural stanchion
that prevents twisting, flex, deflection, and shock damage.
You get the direct power transfer and racy feel of a hardtail,
with a short-travel shock that soaks up the trail’s fatiguing bumps.
When you add extra linkages to a bike’s design,
you get excess lateral motion. That’s not efficient,
and it’s not fast.
Supercaliber engineers ditched the rear pivot
and designed it with wide,
flat seatstays that bow vertically, not laterally.
|Damped and fully tunable
IsoStrut uses a standard shock pump
so you can tune the spring rate for your weight,
and it has a dial for adjusting rebound
and a lockout.
