Trek Top Fuel 9.7 Mountain Bike 2023
Trek's Top Fuel 9.7 Mountain Bike combines progressive geometry with a high-performance Shimano groupset and strong alloy wheels, to create a machine that is both fast and fun, ideal for hitting the trail centre or riding your local tracks.
The Fox Rhythm 34 front fork offers 120mm of smooth travel with excellent tunability capability, and delivers the perfect balance of stiffness and weight, with the design ideal for the rigours of advanced trail riding. The frame features a FOX Performance Float DPS rear shock offering 120mm of travel within the lightweight chassis and providing pedal-friendly performance and a 3-position damper to suit a variety of terrain.
Bontrager's Line wheelset offers a confidence-inspiring feel for control over rough trails, and the wider 29mm rim width supports the tyres' sidewalls for better stability in fast corners. The Shimano Deore drivetrain features a wide-range, 12-speed cassette offering ratios suitable for the steepest hills as well as fast, flat sections.
All-weather stopping power is supplied by the Shimano Deore 4-piston hydraulic caliper and disc rotor system. The brake setup provides consistent performance and controlled confidence on any slope. The internally routed cables keep the cockpit neat and quiet on the trail, while the hidden storage in the downtube offers a solution to carrying tools and nutrition while on the move.
- Active braking pivot allows braking and suspension to work independently for more control
- Integrated internal storage in the downtube for discrete accessory transportation
- Mino Link adjustable geometry allows fine-tuning of the frames angle by simply flipping the link
- Knock Block in the headset prevents the handlebars from spinning in the event of a crash
- Shimano Deore groupset with a 10-51T wide gear ratio
