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 aluminum frame, 120mm RockShox Judy SL fork, 115mm of rear travel with an X-Fusion Pro 2 shock and a wide-range SRAM SX Eagle drivetrain. 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.
favorite_borderWhy you'll love it
- This short-travel bike has a killer suspension setup 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

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. 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.
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.
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 setup.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
