Top Fuel 9.8 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.
It's right for you if...
You’re looking for a do-it-all full suspension mountain bike that's efficient and fast, but doesn't shy away from some bigger stuff. You want the added stiffness and weight savings of a carbon frame, but don't mind saving some money on the parts.
The tech you get
A light and stiff full carbon frame, 120mm RockShox SID Select+ fork, 115mm of rear travel with a RockShox SID Luxe Ultimate shock, and a new Shimano XT 1x12 drivetrain. Plus, wide carbon Bontrager Kovee Elite 30 wheels with a 54-tooth Rapid Drive hub for fast engagement, Bontrager Line Elite Dropper, and carbon handlebars.
The final word
Top Fuel 9.8 is a ridiculously fun carbon down-country bike with upgraded parts that give you noticeable benefits on the trail, like more speed from the carbon wheels and more grip from the ultra-smooth suspension.
Why you'll love it
- This bike wants to go fast—it's built with no-nonsense, high-performance parts
- You get a Straight Shot downtube for extra-stiff, responsive handling without added weight, and a Knock Block headset that protects against spinning bars and fork crowns
- 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 tire support so you can run lower pressure and get more traction
- This short-travel bike has a killer suspension setup reminiscent of the all-mighty mullet—it's both efficient and ready to party
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
Will my bike have a curved top tube?
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. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
