Trek Top Fuel 9 Gen 4 Mountain Bike In Juniper

Season:2025

Brand:Trek

Code:46144GRN

The Top Fuel 9 Gen 4 is an alloy trail bike that's ready to billy-goat up long climbs and rip back to the bottom for another lap.

It gives you the rugged benefits of a lightweight aluminium frame, plus the upgrades you crave, like fully wireless shifting from SRAM's GX Eagle AXS transmission, 4-piston hydraulic brakes and a 120 mm/130 mm FOX suspension package.

It's right for you if...You like balance in most things you do – a combination of climbing power and descending confidence, nimble handling and full-suspension comfort, bike budget and component performance. You like the durability and affordability that an alloy frame offers and want upgrades where they matter most.

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 DPS shock with a 3-position damper. It's topped off with a wireless electronic SRAM GX Eagle transmission, 4-piston hydraulic disc brakes, a Bontrager Line dropper post and Tubeless Ready Bontrager Line Comp 30 wheels.

The final word - The Top Fuel 9 Gen 4 is built for those who want the best of both worlds. It's a great choice for all-around trail riders who may start the day with a pedal fest, but end it with long descents. It delivers on upgrades where you want them most, like your suspension and group set, but keeps the price down with an alloy frame.

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 the sweetest alloy build with a fully wireless SRAM transmission, upgraded suspension and a light yet rugged frame for all-mountain ripping
  • The Alpha Platinum Aluminium frame is robust, yet light, and packs in updated internal frame storage for easy access to gear and snacks
  • It's more upgrade-ready than ever, with room for bigger 140 mm forks and longer-stroke shocks for up to 130 mm of rear travel, plus room for extra-long dropper posts
