Trek Fuel EX 8 Gen 6 Matte Pennyflake

Fuel EX 8 is a dialed trail bike for riders who chase down rowdy descents and want a bike that's happy to pedal back to the top and do it again. It has a stout alloy frame and an upgraded Shimano XT drivetrain for smooth precise shifting. The 150mm Fox Rhythm fork makes easy work of rocks and roots while the Fox Float X shock keeps you in control. New in frame storage and adjustable geometry give you all the perks that come with the carbon model, but without the lofty price tag.

You want a full suspension trail bike that prioritizes suspension and shifting performance over a more expensive carbon frame.

A light and stiff alloy frame with 150mm FOX Rhythm fork with Float EVOL air spring and GRIP damper for small bump compliance, plus a FOX Performance Float X rear shock. A Shimano XT 12-speed drivetrain for snappy shifting, and tubeless-ready Bontrager wheels. Plus, new adjustable geometry that lets you take control of your setup.

For the rider who doesn't want to be limited on the trail, Fuel EX 8 is ready to handle everything. Its progressive trail geometry is built to keep you charging, and upgraded components are the cherry on top.

This bike is built to take on the singletrack, with modern geometry that's evolved to handle the rough and rowdy
You'll get upgraded components where it matters most, with 12-speed XT shifting, and a rock-gobbling FOX Rhythm 36 fork
With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
