Overview

About this bike

Fuel EX 9.9 X0 AXS is a top-tier trail bike built for riders who have an appreciation for the finest things in life. It combines a cream of the crop carbon frame with top-tier components, from the carbon fiber wheels all the way up to the 150mm Kashima-coated FOX Factory fork, and rugged, fully wireless SRAM X0 transmission. It's a bike that rules the mountain and doesn't hesitate to lay claim to its domain, ripping up rock gardens, blasting berms, and rocketing back to the top to conquer it all once again.
