Slash 9.9 XX AXS T-Type Gen 6
Trek
Enduro
Slash 9.9 XX AXS T-Type Gen 6 is a carbon enduro mountain bike (2025), from Trek, in the Slash series. This bike is aimed at riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, and is more at home in gravity-focused bike park riding. Its profile is strongest in areas like strong climbing friendliness for sustained uphill riding, a comfort-leaning ride feel over longer rides, and capable suspension support for rougher terrain. The main limitation versus more focused builds is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
