Top Fuel 9.8 is a high-performance full suspension mountain bike for endurance racers and riders who don’t settle for one style of riding. It combines the best qualities of XC and trail bikes for an unbelievably fun, efficient, and capable rig. It’s fast on flow, shreds big singletrack, and conquers endurance events. The 9.8 is built with an OCLV Mountain Carbon frame and across-the-board parts upgrades, including a 120mm FOX Performance 34 Step-Cast fork, Shimano XT drivetrain, and carbon wheels and bars.

Trek’s Top Fuel is a full suspension XC mountain bike that’s equally suited to racing and having an all-around great time on any trail. It’s fast, fun, and always up for an adventure. Rides XC. And the stuff that scares XC riders.

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. The Shimano hydraulic disc brakes give you stopping power when you need it most. 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.
