It's right for you if...
You want a full-suspension mountain bike that’s fast on flats and rolling terrain, but has enough travel to get wild on the trail. You want a solid build spec at a price that won't break your bike bank.
The tech you get
A lightweight aluminium frame with internal storage, 120 mm RockShox 35 Gold fork, 120 mm of rear travel with an X-Fusion Pro 2 shock and a wide-range Shimano Deore/XT drivetrain. Plus, Bontrager Line Comp 30 wheels that are already completely tubeless ready, including sealant, hydraulic disc brakes, and a dropper post.
The final word
Top Fuel 7 is an awesome and affordable bike that's a blast to whip around on and easier on the wallet. It's fast and fun and perfect for riders who want to test their mettle on all types of trails.
favorite_borderWhy you'll love it

- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
Quick and in control
120 mm 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.
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.
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.
Threaded bottom bracket
More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.
International Standard Chain-Guide mounts offer easy chain-guide installation and adjustment.
