The Trek Procaliber 9.7 SL is an exceptional cross-country bicycle that is equipped with a raft of modern mountain biking technology, the end goal being giving you the ability to rip through the most dastardly of trails without suffering too much.
One of the most intelligently engineered aspects of this magnificent new cross-country bicycle is the incorporation of IsoSpeed coupling, a setup that uses a pivot instead of a fixed joint between the seat tube and the top tube. This ingenious method allows for the top of the seat tube to move independently from the rest of the bicycle frame. This protects the rider in the event of the bicycle hitting a hard bump. The independently moving seat tube also adds a rhythmic feel to your ride which helps you maintain speed and boost your traction.
Ultimately, this cross-country bicycle is a fine example of intelligent engineering technology applied towards the mountain biking realm with a view to improving both comfort and performance.
