• Make the Top Fuel yours - Opt for light parts and a 120 mm fork for a featherweight Top Fuel, or a 140 mm fork and longer-stroke 130 mm rear shock for extra versatility. Room for a longer dropper and MX wheels lets you customise the Top Fuel into an ultimate playful trail whip.

The Top Fuel 9.9 XX AXS Gen 4 is an ultra-light and capable carbon trail bike that's built for soaring up climbs and rallying over miles of singletrack. This top-level build delivers the performance you want, with a RockShox Ultimate suspension package (120 mm/130 mm) and SRAM's lightest wireless XX AXS transmission that shifts smooth and easy, especially under load. It's topped off with carbon wheels to keep your ride light from top to bottom.
