## Overview

The Fuel EX is Trek's full suspension trail bike, and the Fuel EX 8 is one of the aluminium builds in the range. It sits above the EX 5 and EX 7, which pair an aluminium frame with cheaper parts. The carbon framed bikes carry 9 series names such as 9.7, 9.8 and 9.9.

It uses Trek's ABP (Active Braking Pivot) rear suspension, where the rear pivot sits around the rear axle. The idea is to keep the suspension working while you brake.

The Fuel EX name goes back many years and the bike has changed a great deal. Wheel size has moved from 26 inch to 27.5 and 29 inch, and Trek now labels recent versions by generation. Two Fuel EX 8s from different eras share a name and not much else, so the year matters more than usual.

## What it's like to ride

A trail bike, built to be ridden up as well as down. It is meant for all-day rides and trail centre loops where you earn the descents under your own power.

It is not a cross country race bike and it is not an enduro race bike. Riders who only care about climbing speed, or only about the steepest descents, are better served elsewhere.

## Who it's for

Riders who want one mountain bike for trail centres and natural trails and prefer an aluminium frame. It suits buyers who want better suspension and gears than the EX 5 and EX 7 without paying for carbon.

## Good points

- Aluminium frame, which is simpler to inspect for damage than carbon when buying used
- ABP rear suspension, the same design used on the carbon Fuel EX models
- Higher spec suspension and drivetrain than the EX 5 and EX 7
- Trek has a large UK dealer network for parts and servicing

## Considerations

- Model years differ in wheel size, travel and geometry. Check the exact year before comparing prices
- Suspension needs regular servicing, and a neglected fork or shock is costly to put right
- Some model years have Trek specific parts, such as the Knock Block headset that limits how far the bars turn
- Too few used examples tied to this exact model in our UK price data to give a typical price

## FAQs

### What is the difference between the Fuel EX 8 and the Fuel EX 9.8?

The frame material. The Fuel EX 8 has an aluminium frame and the 9.8 has a carbon one. The 9.8 also carries a higher spec. Both use the same ABP suspension design.

### What wheel size is the Trek Fuel EX 8?

It depends on the year. Older bikes have 26 inch wheels and later ones have 27.5 or 29 inch wheels. Check the advert or ask the seller, because tyres, wheels and forks do not swap between sizes.

### How much is a used Trek Fuel EX 8?

We do not have enough UK price data tied to this exact model to give a typical figure. The price depends heavily on the model year and the condition of the suspension. Compare live adverts for the same year.
