Its lightweight carbon frame is specd to the hilt with high-end suspension & high-performance parts. & all those fancy bits & bobs are really, really good at hitting the party line. The Top Fuel 9.9 is built around a light & stiff full carbon frame & is fitted with a 120 mm Fox Factory 34 Step-Cast fork & 115 mm of rear travel from a Fox Factory Float 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 & ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
