Treks Top Fuel 9.7 is a quick & nimble full suspension carbon mountain bike that fuses the efficiency of a cross-country bike with the capability of a trail bike. Its built with a lightweight OCLV Mountain Carbon frame, a 120 mm Rock Shox Reba fork, 115 mm of rear travel & a dropper for serious fun on flowy trails & techy descents alike. Its the kind of unicorn bike that shreds singletrack, stands up to the rigours of endurance racing & even gives traditional XC bikes a run for their money.
