Details
Top Fuel 8 Gen 4 is a spry and snappy 29er ready to make light work of long climbs and cut loose on rowdy descents.
Its adaptable geometry (using its 4-way Mino Link) means it’s at home in almost any terrain, while its svelte, lightweight design makes it a dream to pedal all day long.
Whether you’re heading out for quick midweek hot laps or weekend long adventures packed with lung-crushing climbs and surreal descents, Top Fuel brings something to the party for everyone.
It packs in a versatile 130mm front and 120mm rear travel for ripping over rocks and roots without sacrificing power on ascents.
It's built from lightweight Alpha Platinum Aluminum 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.
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
Top Fuel’s new storage system is easier to use with a bigger opening, more secure seal, and all-new BITS bag system. Carry your essentials on your bike, not your body.
Top Fuel Gen 4 is more upgrade-ready than ever, with room for bigger 140mm forks and longer-stroke shocks for up to 130mm of rear travel, plus room for extra-long dropper posts.
All Top Fuel Gen 4 models are tubeless and ready to go out of the box. Sealant, valves, and rim stips included.
