Description
Built to deliver speed on fast, flowing singletrack, the Trek Top Fuel 9.8 GX AXS Mountain Bike is a fun all-rounder for cross country and trail use. The frame is efficient on hills but does not turn down a techy descent, with its lightweight carbon construction offering stiffness and premium lightweight performance. With 115mm of suspension travel on offer, this bike provides a spritely feel with rapid acceleration and sublime handling.
A Straight Shot downtube enhances rigidity on technical terrain, while a knock-block headset limits the angle of bar rotation to protect the frame from damage. The wide Kovee Elite 30 wheels improve tyre support to enhance traction, with the ultralight carbon construction reducing rotational mass for speedy acceleration.
This bike receives a high-tech specification that includes the fully wireless SRAM GX AXS drivetrain. With its cable-free design, it is trivial to set up and can be customised to your preference through the use of the accompanying SRAM mobile application. The RockShox SID Select+ fork is supple through its 120mm of suspension travel, offering excellent traction on chattery terrain. It is coupled with a RockShox SID Luxe Ultimate rear shock for unrivalled adjustment, and both can be locked out with the Bontrager DropLock system.
