Trek Top Fuel 7 SX Mountain Bike 2021
Offering a blend of lightweight efficiency, speed, forgiveness and adaptability, the Trek Top Fuel 7 SX Mountain Bike is a bike for XC endurance rides, trails and wherever else fun can be had on two wheels. Complete with front and rear suspension, with 120mm and 115mm of travel respectively, this bike soaks up shocks on testing terrain. Thanks to the Mino Link, it can flick between two geometry settings to best suit the terrain - whether the ride calls for a lowered bottom bracket and slacker head tube angle to stay planted in corners, or something a little more aggressive. When descending or sweeping round corners, drop the TransX seatpost to get over the back wheel for a comfortable, safe and more controlled ride.
Tubeless-ready Bontrager Kovee Comp 23 wheels can be set up as such to banish pinch flats and maintain traction at lower pressures, and practical SRAM SX 12-speed components deliver swift and consistent shifting, as well as providing a broad selection of gearing options to fly up climbs. Shimano MT200 hydraulic disc brakes lend sure stopping power regardless of conditions.
The Alpha Platinum Aluminium frame is lightweight, capable and forgiving.
This short-travel trail bike gives you a suspension set-up that’s capable in several MTB disciplines, and especially suited to endurance events.
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 efficiency
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.
