Trek has released the Gen 3 Procaliber. The latest version of Trek's best hardtail mountain bike features three carbon models with updates that include increased fork travel, wider tire clearance, lighter weight, and updated geometry. The highlight according to Trek is the new IsoBow technology which replaces the IsoSpeed decoupling technology seen in previous models.
IsoBow is said to continue Trek's focus on compliance and is claimed to give equivalent seated compliance to the previous IsoSpeed speed system. Rather than decouple the top tube and seat tube, Trek reduces the weight by utilizing the flex of carbon fiber which is said smooth out trail imperfections.
