Fuel EX 9.9 is our best 130mm trail bike. A carbon frame, carbon wheels, a 1x12 SRAM X01 Eagle drivetrain, and FOX Factory Float suspension make this the one carbon full suspension mountain bike that rules every trail. It's fast on XC singletrack, light on climbs, and stable through the rowdiest terrain you can find.
