Trek Top Fuel 9.9 X01 Mountain Bike 2021
A combination of weight-saving carbon, high-end components and plush FOX dual suspension, the Trek Top Fuel 9.9 X01 Mountain Bike is a capable steed that roars down trails and is agile on endurance rides. Heightened confidence at speed is ensured by the slacker head tube angle, which also makes for a more forgiving ride when the miles start to stack up. Geometry can be altered by flipping the Mino Link, changing it from trail-focused with a head tube angle slackened by half a degree and lowered bottom bracket to a more aggressive position. Get over the back wheel quickly with the Bontrager Line Elite Dropper seatpost, ideal for more comfortable, controlled and safer descending. 120mm of travel from the FOX Factory fork and 115mm of rear travel are tuned to conquer varied terrain and can be remotely locked out when a burst of power is needed during climbs or sprints.
Internal cable routing makes for a clean silhouette and boosts practicality, ensuring no exposed cables are muddied up and shifting is never compromised. Top-tier SRAM X01 Eagle 12-speed components operate silently, shifting with precision, reliability and providing a wider range of gearing options for testing climbs - whilst the 1x drivetrain guarantees hassle-free post-ride maintenance. Pro-level carbon Kovee Pro 30 wheels blend light weight with durability and can be run tubeless for great traction at lower pressures.
The full carbon frame gives you a light, responsive ride.
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.
Wider Kovee Pro 30 wheels provide better tyre support so you can run lower pressure and get more traction.
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.
