Description
The Top Fuel 8 fuses the speed of a cross-country bike with the capability and forgiveness of a full-suspension trail bike. It's quick and nimble, and dishes out serious fun on flow trails and techy descents alike.
Top Fuel 8 is perfect for you if you're looking for a do-it-all full-suspension mountain bike that balances efficiency with shred-ability. You want to rip rough descents, fly up climbs and crush lap after lap.
The Trek Top Fuel 8 features a lightweight aluminium frame with internal storage, 120 mm RockShox SID fork with plush DebonAir spring, 120 mm of rear travel with a FOX Performance Float shock and a Shimano XT drivetrain. Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already completely tubeless ready, including sealant, and a Bontrager Line Dropper.
The Top Fuel 8 gets you the value of an alloy frame with drivetrain, fork and brake upgrades that keep up as you progress in speed and skill.
Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.
IMPORTANT: This bicycle is supplied without pedals.
IMPORTANT: This bicycle requires a suspension pump to set and tune its suspension correctly. This is not included as standard.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
