The minimalist design and the storage compartment in the down tube are probably the most obvious changes of the Top Fuel 9.9 XX AXS compared to its predecessor. Slightly less noticeable: The bottom bracket is now threaded instead of pressed. With a flat 65,5 degree head tube angle and a long reach, the geometry corresponds to the current trend. The upright seating position gives the Trek a comfortable character. On the downhill, however, the Trek Fully is left in the dust by its competitors. Trek is installing only absolutely high-quality shifting components. A nice warranty promises sustainability. With 25 years warranty Trek sets the bar high!
