Trek's 2025 Fuel EX 8 GX AXS is a trail bike designed for riders looking to ride challenging descents and want a bike that's willing to pedal back to the top, lap after lap. The lightweight aluminum frame is paired with the SRAM GX Eagle 12-speed wireless electronic drivetrain, while the 150mm FOX Rhythm fork absorbs impacts from stones and roots. In-frame storage and adjustable geometry offer all the benefits of the carbon model, but at a more affordable price.
It is ideal for you if...
You want a full-suspension trail bike that floats through the most demanding, technical terrain, and has additional benefits, like the root-absorbing FOX Rhythm fork and tubeless wheels.< /p>
Features
The Fuel EX Gen 6 has 140/150mm travel with additional adjustment features and more stable handling, plus a more robust frame with storage
You'll enjoy updated components where it matters most, with SRAM's latest GX Eagle AXS wireless electronic drivetrain for smooth shifting under load.
The headset with adjustable angle (angled cups sold separately) and the Mino Link allow you to choose from six different geometry configurations.
The telescopic post allows you to lower the saddle on the fly so it doesn't get in your way in the descents.
