La superleggera OCLV MTB Procaliber SL porta il decoupler IsoSpeed, una tecnologia collaudata ai massimi livelli nelle corse su strada e nel ciclocross, nel mondo off road. Il nuovo Procaliber porta il Boost 148 e il Boost 110 a una interfaccia ancor migliore che con ruote da 29 rende ancora più semplice l'arrampicata e la guidabilià. Inoltre, Procaliber SL sarà offerto in Formato Smart così che si possa adattare alla ruota prescelta dall’atleta senza problemi. Ruote da 29" saranno disponibili su telai di medie e grandi dimensioni, quelle da 27,5" per le taglie piccole. Il collaudato e popolare Superfly rimarrà disponibile sia in carbonio che in lega OCLV. 

Nel corso degli anni, le gare cross country sono diventate più esigenti, i sentieri più tecnici, sfidando le marche a sviluppare soluzioni più efficaci per i corridori. Trek Top Fuel concentra quanto studiato e imparato negli anni di esperienza sui trail grazie ad atleti del calibro di Emily Batty, Bec Henderson, Dan McConnell, Sergio Mantecon e Kohei Yamamoto, dispone di suite completa di Attivo Pivot frenata, Full Floater e EVO Link per una sospensione ottimale che non limita la velocità. Top Fuel sarà disponibile sia in carbonio OCLV MTB e modelli Alpha Platinum alluminio. Top Fuel sostituisce il Superfly FS nella proposta Trek. 

Trek has released two new platform-redefining cross country bikes with the unveiling of the revamped Top Fuel and the Procaliber SL. Both bikes represent Trek's commitment to providing the most technologically sophisticated product for the most discerning mountain bikers. 

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 . 

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. 

Trek Factory Racing's XC contingent of Emily Batty, Bec Henderson, Dan McConnell, Sergio Mantecon, and Kohei Yamamoto have been racing both the Procaliber SL and Top Fuel all season. The biggest challenge the new bikes have presented to the team is the decision on which of the two new bikes to choose for each course. Both Procaliber SL and the carbon Top Fuel will be available in Project One, Trek’s custom bike program and available exclusively through Trek's network of globel retailers.
