Trek unveils all-new Top Fuel & Procaliber SL

Trek has 2 new bikes on the way – the Top Fuel and Procaliber SL are squarely aimed at XC and feature a host of new features. Each model has some really interesting new features and refinements that we’ll take a look at below.

Top Fuel :


Throughout the years, cross country racing has become more demanding, the trails more technical, challenging brands to develop more capable solutions for riders. Trek’s Top Fuel utilizes the company’s years of experience developing trail bikes to create a more capable full suspension race bike that doesn’t sacrifice any speed. Top Fuel features Trek’s full suite of suspension breakthroughs – Active Braking Pivot, Full Floater, and EVO Link – that allows for active, yet efficient suspension.









Mino Link allows the rider to tweak frame geometry for a slightly more active or slack geometry depending on their preference or trail. New technologies include Boost 148/110 which allowed for stunningly short chainstays on a race bike making it more agile and superior for climbing. Top Fuel also gets Smart Wheel Size so everyone, regardless of size, gets the fastest wheel that fits. Top Fuel will be available in both OCLV MTB carbon and Alpha Platinum Aluminum models. Top Fuel replaces the Superfly FS in the Trek lineup.

Procaliber SL :

The lightweight OCLV MTB Procaliber SL brings the IsoSpeed decoupler, a technology proven at the highest levels of road and cyclocross racing, to the mountain bike racing scene. As road cyclists and cyclocross racers can attest, IsoSpeed takes the edge off of a hardtail ride without any sacrifice in pedaling efficiency, completely redefining what a hardtail can be.








The new Procaliber carries Boost 148 and Boost 110, creating a stronger, better, 29er wheel and interface that allows for shorter chainstays, improving climbing and playfulness. In addition, Procaliber SL will be offered in Smart Wheel Size which allows all riders to ride the fastest wheel that fits. 29” wheels will be available on medium and large frame sizes, while 27.5” wheels can be found on small frame sizes. Though the new Procaliber SL will sit atop Trek’s hardtail lineup, the proven and popular Superfly will remain available in both OCLV carbon and alloy.
