Trek Top Fuel 8 Gen 4
The Top Fuel 8 Gen 4 is an agile aluminum trail bike that offers an outstanding balance of fast uphill efficiency and confident downhill performance. With 130 mm of front travel and 120 mm of rear travel, it’s versatile enough to handle rocks and roots with ease and tackle uphills efficiently. It’s built around a lightweight Alpha Platinum aluminum frame, which keeps the bike’s price affordable, and features performance upgrades where they matter most—such as the Shimano XT/SLX 12-speed drivetrain and the FOX Rhythm 34 fork.
