From Trek

All-new IsoBow

The new Procaliber Carbon forgoes the IsoSpeed decoupler used in previous iterations, instead opting for the all-new IsoBow trail-smoothing tech. IsoBow works by continuing the seatstays beyond the seat post, allowing them to flex and dissipate vibrations from roots, rocks, and rough sections of trail. This elevates comfort and preserves energy for explosive climbs and attacks, all the while shedding material for a ride that’s not only more comfortable, but lighter, too.

More capable than ever

With XC courses getting gnarlier every year, hardtails need to adapt to keep up. Trek's engineers gave Procaliber just the updates it needs to stay at the front of the pack. A new longer-travel 120mm fork helps soak up roots and rocks, while a slacker 67° head tube and longer reach elevate stability for faster descents. The new frame rolls on a set of 29˝ wheels to keep rolling resistance down and help riders get more distance out of every pedal stroke.
