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, 120 mm RockShox SID Select+ fork, 115 mm of rear travel with a RockShox SID Luxe Ultimate shock and a new SRAM GX Eagle drive train with an extra-low 52-tooth climbing gear. 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 tyre support so you can run lower pressure and get more traction
- This short-travel bike has a killer suspension set-up reminiscent of the all-mighty mullet – it's both efficient and ready to party
