Trek Top Fuel 9.8 GX 29" Mountain Bike 2020
The Trek Top Fuel 9.8 GX 29" Mountain Bike is ready to tackle almost any trail, all day long. The dual suspension system is set up to provide enough travel for the majority of MTB disciplines and can be locked out at the flick of your wrist using the TwistLoc lever. Drop the seat post for steep downhill sections, and modify the bike's geometry mid-ride using the handy Mino Link.
The SRAM GX Eagle 12-speed gears provide enough range for any gradient, while the Shimano M7000 hydraulic disc brakes deliver impressive stopping power. Rolling on a set of 29" tubeless ready carbon clinchers, the Bontrager Kovee bring durability and speed on the ascent and descent. The clean lines of the lightweight carbon fibre frame are achieved thanks to the Control Freak internal cable routing, which keeps your hoses and cables out of harm's way.
- This bike wants to go fast – it's built with no-nonsense, high-performance parts
- You get a Straight Shot downtube for extra stiffness in the rough and Knock Block frame defence to protect against spinning bars and fork crowns
- TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
- Wider Kovee Elite 30 wheels provide better tyre support so you can run lower pressure and get more traction
- This short-travel trail bike gives you a suspension set-up that’s capable in several MTB disciplines, and especially suited to endurance events
