Trek Top Fuel 8 GX AXS T-Type Gen 3
Details
Top Fuel 8 fuses the speed of a cross country bike with the capability and forgiveness of a full suspension trail bike. It's quick, nimble, and dishes out serious fun on flow trails and techy descents alike. Plus, you get the upgrade of wireless electronic shifting.
IT'S RIGHT FOR YOU IF…
You're looking for a do-it-all full suspension mountain bike that is efficient yet can get rowdy. You want to rip rough descents, fly up climbs, and crush lap after lap.

Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already set up tubeless, including sealant, and a Bontrager Line Dropper.
THE FINAL WORD
