Features

Product features

Quick and in control

120mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.

Hassle-free routing

Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.

Will my bike have a curved top tube?

The smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.

You almost forgot your pedals

This bike doesn’t come with pedals because you'll have a better ride if you choose your own. Explore the pedal guide to find the best pedals for your riding style. Reach for flat pedals for simple versatility or go for clipless MTB pedals if you want control and efficiency.

Complete Tubeless System

Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Oversized 34.9mm dropper post

Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.

ISCG mounts

International Standard Chain-Guide mounts offer easy chain-guide installation and adjustment.

Threaded bottom bracket

More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.

Knock Block

Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
