2026 Trek Top Fuel RSL Gen 4 Mountain Bike
Top Fuel RSL takes the ride-anything capability of our favorite short-travel trail bike and ups the race-ready factor. Its OCLV Mountain Carbon frame partners with a 120mm RockShox SID Ultimate fork and 120mm SIDLuxe Ultimate shock — both with Flight Attendant. It comes ready to rally with Bontrager Kovee Elite 30 carbon wheels, a SRAM X0 AXS 12-speed wireless transmission, a Bontrager Line dropper post, and a carbon Bontrager RSL integrated handlebar/stem.
