Details

Top Fuel 9.8 is a high-performance full suspension mountain bike for endurance racers and riders who don't settle for one style of riding. It combines the best qualities of XC and trail bikes for an unbelievably fun, efficient, and capable rig. It's fast on flow, shreds big singletrack, and conquers endurance events. The 9.8 is built with an OCLV Mountain Carbon frame and across-the-board parts upgrades, including a 120mm FOX Performance 34 Step-Cast fork, Shimano XT drivetrain, and carbon wheels and bars.

It's right for you if...
You want an efficient, capable, short-travel trail bike that excels at endurance and stage racing and can handle rough trails and even XC races. You appreciate the performance advantage of carbon and want a superlight bike with race-level components and suspension.

The tech you get
A full OCLV Mountain Carbon frame, upgraded 120mm Fox Performance 34 Step-Cast Float fork with GRIP damper, 115mm of rear travel with a FOX Performance Float shock, and a 1x12 Shimano XT drivetrain. Plus, wide carbon Bontrager Kovee Elite 30 wheels with a 54-tooth Rapid Drive hub for fast engagement, TwistLoc dual remote suspension lockout, Bontrager Line Elite Dropper, Bontrager Line Pro OCLV Carbon handlebar, and upgraded Shimano SLX brakes.

The final word
Top Fuel 9.8 is an efficient, capable, and ridiculously fun short-travel carbon trail bike with the performance boost of upgraded parts like the drivetrain, fork, and brakes. It's built to rip technical terrain and descents, speed through flow sections, and withstand the beating endurance races dole out.

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 down tube for extra stiffness in the rough and Knock Block frame defense 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 tire support so you can run lower pressure and get more traction
- This short-travel trail bike gives you a suspension setup that’s capable in several MTB disciplines, and especially suited to endurance events

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.
