Trek Top Fuel 9.9 XX AXS Gen 4 - Lunar Silver

The Top Fuel 9.9 XX AXS Gen 4 is an ultra-light and extremely powerful carbon trail bike built for efficient climbs and miles of singletrack adventures. This top-class trail bike offers ultimate performance: a RockShox Ultimate suspension package with 130 mm front and 120 mm rear travel and SRAM's lightest wireless XX AXS transmission for particularly smooth and precise gear changes.
