Trek Top Fuel 9.8 is a full suspension carbon mountain bike for riders who don’t settle. Not for parts nor for one style of riding. It combines a high-end parts package with a low-weight carbon frame for one unbelievably fun rig that’s fast on flow and fun to ride on techy singletrack.

If you’re looking for a do-it-all full suspension mountain bike that’s efficient and fast, but doesn’t shy away from some bigger stuff. You want the added stiffness and weight savings of a carbon frame, but don’t mind saving some money on the parts.

Top Fuel 9.8 is a ridiculously fun carbon down-country bike with upgraded parts that give you noticeable benefits on the trail, like more speed from the carbon wheels and more grip from the ultra-smooth suspension.

The Top Fuel is the perfect trail bike for South Florida, but it’s also a great option for out of the area trail adventures. With 120mm front travel, South Florida’s cross country, technical, and flowy terrain are a playground for the Top Fuel. The dropper seat post gives you the flexibility to put your body where you need it for steep drops. It’ll be your daily ride at Club Scrub in Jonathan Dickinson State Park all week long. Then, it’ll be your weekender up at Santos in Ocala or Alafia near Tampa.
