The Top Fuel family brings World Cup performance to you, making every inch of trail go by that much faster.
When Trek revived the Top Fuel moniker, it knew it had to keep the incredible features from the Fuel EX line that make it such a world-beater in trail bikes. The Active Braking Pivot -or ABP- rear suspension geometry makes the Top Fuel a true standout in full-suspension cross country mountain bikes. Instant reaction to changing surfaces and terrain, as well as zero shock compression during hard braking make the Top Fuel a winner in the arena of race-ready full suspension machines. Adding all that race-bred tech to an OCLV Mountain carbon fiber frame elevates the Top Fuel 9.8 beyond its competitors, ensuring feather-light weight and incredible torsional strength. Trek's frame geometry has been proven time and again during cross-country races around the world, and that geometry is found on this Top Fuel as well. A tapered head tube adds an extra dash of razor-sharpness to the Top Fuel's handling, while a press-fit PF92 bottom bracket anchors the SRAM crankset for flex-free power delivery. Control Freak internal cable routing keeps the Top Fuel 9.8 looking clean and sleek with no rattles, while carbon armor under the down tube resists flying gravel and debris. The Top Fuel's overall geometry can be tweaked slightly by rotating the Mino Link suspension pivot at the top of the rear stays. Want a more relaxed geometry? simply rotate the Mino Link to get a slacker head angle for a more stable feel.
Out back, the air-adjustable RockShox SID Luxe Ultimate shock keeps the Top Fuel 9.8 anchored to the singletrack. From small-bump compliance to hard landings, SID Luxe rear shock responds to everything with just the right amount of response, keeping you in control with 115mm of travel. Up front, an air-adjustable RockShox SID Select+ suspension fork helps tackle rock gardens and root "fun houses" with 120mm of travel. A 15mm thru-axle keeps the front wheel where you point it, while a 2-position damper adds even more control, depending on rider preference.
SRAM has been at the forefront of mountain bike component tech, and their latest 12-speed SRAM GX Eagle components are no exception. A SRAM GX Eagle shifter and GX Eagle Roller Bearing Clutch rear derailleur operate with lightning-quickness, even under hard pedaling loads. A 12-speed SRAM Eagle XG-1275 10-52T cassette and SRAM GX 7K Eagle crankset with a direct-mount 32T chainring offers a massive gearing range for challenging trails and climbs. A SRAM Eagle chain is there to make sure shifting and power transfer is all top-notch. Bontrager's tubeless-ready Kovee Elite 30 wheels are shod with 29x2.40" tubeless-ready XR3 Team Issue tires, bringing bags of grip and easy acceleration to the Top Fuel 9.8. The Kovee Elite wheelset features Boost110/148 hubs, adding wider flanges for improved lateral rigidity in the wheels. Helping to keep speed reigned in is a set of SRAM G2 RS 4-piston hydraulic disc brakes that outperform the competition's garden-variety 2-piston stoppers. A Ti-railed Bontrager Montrose Elite saddle sits atop an alloy Bontrager Line Elite dropper seatpost, while an alloy Bontrager Kovee Pro stem and Line Pro OCLV carbon fiber handlebar complete this race-ready machine.
Do you have racing aspirations, but don't want to break the bank? How about a full-suspension machine that climbs as well as it descends? Trek's Top Fuel line has an entry-level model that won't disappoint.
The Top Fuel range of mountain bikes from Trek have been at the leading edge of off-road technology for years. Athletes have won national championships and world championship medals aboard Trek's Top Fuel platform, and now you can own one at a more affordable price level. Trek built the Top Fuel 7's chassis with their proprietary Alpha Platinum aluminum, keeping overall weight low for exceptional climbing and maneuverability in tight quarters. A threaded bottom bracket and tapered head tube anchor the crankset and fork for a responsive feel in technical and challenging terrain. A clever Knock Block headset-mounted steerer stop prevents the fork crown from denting the frame's down tube in the event of an unexpected inspection of the greenery. Progressive frame geometry brings confident handling to every inch of singletrack. The Top Fuel 7's race-proven Active Braking Pivot (or ABP) rear suspension geometry helps keep the rear wheel planted on technical trails without absorbing pedaling force or contracting under hard braking. The suspension's upper EVO link prevents lateral biding in the rear shock, allowing it to operate smoothly in rough terrain. Need to tweak the geometry for different trails? The reversible Mino Link chip at the bottom mount of the rear shock can be flipped to alter the bike's center of gravity and handling. Cool, huh? The air-adjustable Fox Performance Float DPS rear shock is air adjustable, allowing the bike to be set up for lighter or heavier riders with a shock pump. Up front, an air-adjustable RockShox 35 Gold RL suspension fork boasts 120mm of travel, just like the rear suspension. Control Freak internal cable routing and a downtube-mounted guard lets you know Trek made the Top Fuel 7 to get dirty. An internal storage compartment in the downtube under the bottle cage mounts eliminate the need for a seat bag.
Shimano supplies the drivetrain components for the Top Fuel 7, bringing additional tech to a winning platform. A 12-speed Shimano SLX shifter and clutch-equipped Deore XT rear derailleur cover gear change duties on the Top Fuel 7, bringing precise operation and durability at your fingertips. A massive Shimano Deore 10-51T cassette offers plenty of gearing range for roller-coaster race courses and trails, while a single-ring Shimano Deore crankset and direct-mount 30T chainring keep rotating weight low. The Top Fuel 7's wheels are Bontrager's tubeless-ready alloy Line Comp 23's, featuring Boost110/148 thru-axle hub spacing for an extra dash of handling prowess. Aggressive tubeless-ready 29x 2.40" Bontrager XR4 Team Issue tires boast plenty of traction and low rolling resistance. Shimano supplies the hydraulic disc brakes, ensuring plenty of stopping power in all conditions, rain or shine (or mud...). A Bontrager Arvada saddle sits atop an alloy TranzX dropper seatpost that operates with a remote lever on the handlebar. An alloy Bontrager Rhythm Comp stem and alloy Comp handlebar complete this value-packed adventure-ready warrior.
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 could be the best full-suspension XC racer on the planet. It's absurdly light at less than 25 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 over rough trails. 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 downhill 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 Top Fuel 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 the aforementioned 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 single 32T direct-mount 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 reduce 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.
