This is Trek's answer to the question: Who makes a world-beating cross-country mountain bike that can handle marathon-length events?


The Top Fuel 9.9 is possibly the best full-suspension XC racer on the planet. It's absurdly light; only 25.3 pounds (!!) when set up tubeless. The main frame and rear suspension arms are all made from Trek's exclusive OCLV Mountain carbon fiber, bringing incredible strength to handle every pedal stroke. Every aspect of the main frame has been optimised for high performance without adding pounds. The frame's Straight Shot downtube eliminates plenty of material while enhancing torsional strength. Don't worry, the fork crown won't whack the down tube during a crash, thanks to a clever Knock Block steerer stop at the top of the head tube. Out back, the Active Braking Pivot (or ABP) full suspension geometry isolates braking forces from suspension movement, so every gnarly hairpin won't feel like a major test of your riding talents. Control Freak internal cable routing, a tapered head tube, and downtube-mounted Carbon Armor are examples of the details that make every Trek mountain bike a clear leader in XC racing machines.


The air-adjustable RockShox Pike Ultimate suspension fork helps to tame rock gardens and challenging course features with ease. 120mm of travel soaks up impacts, while a bar-mounted lockout twist-lever shuts off the shock when charging along hardpan and jeep doubletrack. The rear shock is also a RockShox Deluxe Ultimate unit, bringing 115mm of travel and a lockout function.


Trek chose SRAM's best off-road drivetrain for the Top Fuel 9.9: 12-speed Eagle AXS. Yes, this is the wireless shifting SRAM drivetrain for mountain bikes. Powered by a rechargeable Li-Ion battery, every shift is perfect. Every. Single. Time. The XX1 AXS rear derailleur can handle hard pedaling loads and poorly-timed shifts with ease. Plus, there's no shift cable or housing to get nasty in messy conditons! Cool, huh? A 10-50T SRAM Eagle rear cassette boasts a massive gearing range for roller-coaster trails and courses. Power delivery is done through a carbon fiber SRAM XX1 Eagle crankset with a 32T single chainring.


Bontrager supplies the tubeless-ready OCLV carbon fiber Kovee Pro 30 wheelset. The 30mm-wide internal rim width allows the tire to spread out for better trail contact, enhancing lateral grip and lower rolling resistance. Boost110/148 thru-axle hubs improve lateral rigidity, while a Rapid Drive 108 rear freehub makes pedaling response lightning-quick. With a total wheelset weight of only 1500 grams (without tires or cassette), the Top Fuel 9.9 will leap out of corners and hairpins like a jackrabbit!  Bontrager's 29x2.4" XR3 Team Issue tires are also tubeless-ready, bringing bags of grip to any trail surface. SRAM Level Ultimate hydraulic disc brakes boast excellent stopping power in all conditions, rain or shine (or mud).


The Top Fuel 9.9's RockShox Reverb AXS dropper post is just as high-performance as the rest of the bike. It's wireless, using a bar-mounted remote lever for clean installation, and uses the same rechargeable battery as the SRAM XX1 Eagle AXS rear derailleur. A carbon-railed Montrose Pro saddle, Kovee Pro stem, OCLV carbon fiber Line Pro handlebar complete this world-beating off-road racer.


A SRAM eTap AXS battery charger is included with the purchase of this bicycle.
