Season:2026

Brand:Trek

Code:46143BLK

The Top Fuel 8 Gen 4 is a nimble alloy trail bike that strikes a balance between quick climbing efficiency and descending confidence.

It packs in a versatile 130 mm front and 120 mm rear travel for ripping over rocks and roots without sacrificing power on ascents. It's built from lightweight Alpha Platinum Aluminium that helps save your budget for bike trips, but packs in upgrades where they matter, like a 12-speed Shimano XT and SLX drivetrain, and a Fox Rhythm 34 fork.

It's right for you if...You want an alloy full suspension that's ready to rip. You like to ride everything from cross-country hot laps to all-mountain adventures, and you need a bike that's light, versatile and confident. You've got an appreciation for the durability of aluminium, but want upgrades where they matter, like your drivetrain and suspension.

The tech you get - An Alpha Platinum Aluminium frame equipped with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130 mm FOX Rhythm 34 fork with Float EVOL air spring and GRIP damper, plus 120 mm of rear travel from a FOX Performance Float shock with a 3-position damper. It's topped off with a Shimano XT/SLX 12-speed group set, hydraulic disc brakes, a Bontrager Line dropper post and Tubeless Ready Bontrager Line Comp 30 wheels.

The final word - The Top Fuel 8 Gen 4 is ready to cut loose from all-day climbs to rooty descents. It balances capability and efficiency, with just enough travel to keep the ride smooth without eating up your pedalling power. It gives you the perfect blend of affordability, with a rugged alloy frame and upgrades where they matter, like the Shimano XT/SLX drivetrain.

Features:

  • Its lightweight frame and versatile geometry make it the perfect choice for all kinds of rides and all kinds of riders
  • The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride
  • You get a sweet balance of price and performance with upgraded components and a rugged alloy frame
  • The Alpha Platinum Aluminium frame is robust, yet light, and packs in updated internal frame storage for easy access to gear and snacks
