The Trek Fuel EXe 9.9 XX AXS is mountain biking elevated. It rolls into untouched terrain that lies between traditional mountain bikes and electric bikes with new technology that silently blends in with nature and the finest components the industry offers. From its light and stiff carbon frame and wheels to a tiny but mighty TQ transmission, the EXe 9.9 is eager to rally any trail. It spares no expense, with a SRAM XX AXS transmission that’s as light as it is precise, and it’s loaded with an ultimate RockShox suspension package equipped with AirWiz technology to keep your set-up dialled just to your liking.
