2021 Trek Top Fuel 9.8 GX Full Suspension Mountain Bike in Carbon

The 2021 Trek Top Fuel 9.8 GX Full Suspension Mountain Bike in Matte Carbon is a full suspension carbon mountain bike for riders who don’t settle. Not for parts nor for one style of riding. It combines a high-end parts package with a low-weight carbon frame for one unbelievably fun rig that’s fast on flow and still fun to ride on techy singletrack. The Top Fuel 9.8 is built around a light and stiff full OCLV carbon frame and comes fitted with a 120 mm RockShox SID Select+ fork and 115 mm of rear travel from a RockShox SID Luxe Ultimate shock. The frame comes with Mino Link which lets you make small adjustments to the geometry with the turn of a single bolt, even during a ride. Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height. The Top Fuel 9.8 GX comes with the new SRAM GX Eagle 1 x 12 speed drive train with an extra-low 52-tooth climbing gear. This is a bike built for speed so it comes with wide carbon Bontrager Kovee Elite 30 wheels which are tubeless ready and have a 54-tooth Rapid Drive hub for fast engagement. A Bontrager Line Elite Dropper post and carbon handlebars round out the build. This bike is perfect for Mountain bikers who want a do-it-all full suspension bike that’s efficient and fast, but doesn’t shy away from some bigger stuff. It uses carbon on the frame and wheels but this is a build focussed on performance rather than all out bling. Key Features Full carbon frame with 120mm travel at the front and 115mm at the back 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 efficiently. Plus, it controls your dropper post too Wider Kovee Elite 30 wheels provide better tyre support so you can run lower pressure and get more traction 12 Speed SRAM GX Eagle rive train and SRAM hydraulic brakes
