About this bike
Top Fuel 7 is a full suspension mountain bike that combines the speed of a cross country bike with the go-for-it gusto of a trail bike. It's efficient up climbs and fast on sprints, but it's not afraid of letting loose when you want to get rowdy. 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. Why 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
