The Top Fuel 9.8 is a full-suspension carbon mountain bike for those who don’t compromise on parts and don’t want to compromise on purpose. This package combines high-end parts – such as the new wireless electronic SRAM GX Eagle AXS drive – with a lightweight carbon frame to create an impressive fun machine that’s fast on flowy sections and really fun on technical singletrack.
It’s the right bike for you if…
… you are looking for a versatile full-suspension mountain bike that is efficient and fast and doesn’t shy away from rough trails. You also want to enjoy the higher stiffness and lower weight of a carbon frame and the outstanding performance of completely wireless electronic shifting.
You get this equipment
A light and stiff full carbon frame, a RockShox SID Select+ fork with 120mm of travel, a RockShox Deluxe Ultimate RCT shock with 120mm of travel and a wireless SRAM GX Eagle AXS electronic drivetrain with an extra-large 52-tooth climbing gear. It also comes with wide Bontrager Line Elite 30 carbon wheels with a Rapid Drive hub with 108 teeth for instant traction, a Bontrager Line Elite dropper post and carbon handlebars.
Our last word
The Top Fuel 9.8 is a carbon-framed down-country bike with high-quality components that offer huge benefits on the trail – like carbon wheels for more speed, supple, responsive suspension for more traction and SRAM AXS drivetrain for more precision gear change.
Why you will love it
- The SRAM GX Eagle AXS drive shifts intelligently, smoothly and completely wirelessly.
- A slim storage compartment integrated into the frame allows for the storage of tools and equipment.
- Its impressive chassis setup works efficiently and goes along with any nonsense.
- The wider Line Elite 30 wheels improve tire support so you can run lower tire pressures for more traction.
Features
Active Braking Pivot
Active Braking Pivot allows our engineers to fine-tune how the suspension responds independently to acceleration and braking forces. This gives you more confidence in critical situations.
Fast and sovereign
The 120 mm rear suspension travel and the progressive trail geometry ensure dynamic, agile handling so that you can always stay cool even on rough trail sections.
Integrated storage compartment
Thanks to the integrated storage compartment, you can leave your backpack at home without having to do without the essentials for your trip.
Uncomplicated cable routing
With rattle-free internal cable routing, the Top Fuel is quiet on the trail and easy to service in the shop.
Does my bike have a curved top tube?
On the smaller frames (XS and S), the top tube is curved. This design provides a lower standover height, which benefits smaller riders when getting on and off. The larger frames (from size M) come with a straight top tube, as taller riders usually have no problem with the standover height.
Complete tubeless system
Tubeless Ready rims and tires make it easy to convert to a tubeless system – for more traction, fewer punctures and lighter weight. Thanks to the included TLR rim strips, TLR valves and sealant, you can start converting immediately.

Carbon Care Wheel Loyalty Program
Every Bontrager carbon wheel is covered by our Carbon Care Wheel Loyalty Program. In the unlikely event that you damage your Bontrager carbon wheels within the first two years of your original purchase, we’ll repair or replace them for free.
Oversized dropper post 34.9mm
bigger is better The oversized seat tube offers increased support and stability for dropper posts with more travel and allows the use of a stronger, more durable inner workings that work faster.
Screwed bottom bracket
Bolted bottom brackets are more robust than press-fit bearings, withstand the toughest conditions and simplify maintenance.
ISCG shots
Thanks to the chain guide mount according to the ISCG standard, a chain guide can be easily attached and adjusted.
Knock block
Knock Block protects your frame when things don’t go smoothly. The steering stop prevents your handlebars from being turned completely in the event of a fall, in order to avoid excessive pull on your cables and to prevent the handlebars from contacting the top tube.
Geometry adjustable via Mino Link
Adjust head angle (by 0.5°) and bottom bracket height (by up to 10mm) by simply turning a threaded nut. Turn the threaded nut and choose between a slack and an even slacker geometry without affecting the performance of the chassis. Another exclusive Trek technology.
