Trek Fuel EX 8 Gen 7 Mountain Bike 2026 - Trail Full Suspension MTB
The Trek Fuel EX 8 Gen 7 brings more trail-taming confidence than ever before. Designed for riders who love technical singletrack and fast, flowing descents, this full-sus MTB comes equipped with a tough yet lightweight Alpha Platinum aluminium frame. The latest geometry updates give it a longer, slacker feel that boosts stability on steep terrain, while the adjustable headset cups and Mino Link system let you fine-tune the ride to suit your trails and style.
Key Features:
- Alpha Platinum aluminium frame with internal storage and adjustable geometry
- Fox Rhythm 36 fork with GRIP damper and 150 mm of front suspension travel
- Fox Performance Float X rear shock with 145 mm travel and 2-position damper
- SRAM Eagle 70 T-Type 12-speed drivetrain with wide 10-52T cassett
- SRAM DB8 4-piston hydraulic disc brakes for confident stopping
- 29” Bontrager Line TLR wheels with Brevard Pro XR tyres
- Angle-adjust headset and Mino Link adjustable suspension
- Available with 0% APR finance
Up front, you get the reliable and plush Fox Rhythm 36 fork with 150 mm of travel and the GRIP damper, perfect for smoothing out chunky rock gardens and root sections. At the rear, a Fox Performance Float X shock delivers 145 mm of controlled travel, ideal for both big hits and technical climbs.
The bike is built around SRAM’s Eagle 70 T-Type 12-speed drivetrain, delivering precise, smooth shifts even under load thanks to its direct-mount mech and wide-range 10-52T cassette. You’ll also get confident, powerful braking from the SRAM DB8 4-piston hydraulic discs, designed to hold up to repeated descents without fading.
Rolling on 29” Bontrager Line TLR wheels wrapped in grippy Brevard Pro XR 2.5” tyres, the Fuel EX 8 is ready to carve corners and hold speed. A Bontrager Line dropper post with 170 mm travel ensures you're in control when the trail points down.
From trail centre loops to natural, all-day rides, the Fuel EX 8 Gen 7 is a true all-rounder that adapts to your riding. If you're after one bike that can confidently tackle a wide variety of terrain and grow with you as your riding pushes further, this is a strong contender.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
