It's right for you if...
You want a full-suspension mountain bike that’s fast and efficient on flats and rolling terrain, but has enough travel to get a little 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, 120 mm RockShox Judy SL fork, 115 mm of rear travel with an X-Fusion Pro 2 shock and a wide-range SRAM SX Eagle drive train. Plus, hydraulic disc brakes, Bontrager DropLock dual remote suspension lockout 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.
The Walkthrough
favorite_borderWhy you'll love it
- This short-travel bike has a killer suspension set-up reminiscent of the all-mighty mullet – it's both efficient and ready to party
- Bontrager DropLock's shifter-style lever lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiently. Plus, it controls your dropper post too
- Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
- You get a Straight Shot downtube for extra-stiff, responsive handling without added weight and a Knock Block headset that protects against spinning bars and fork crowns
Features
Will my bike have a curved top tube?
Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.
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.

Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
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.

Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
