The Top-Tier Trail Hardtail
The Marlin 8 2022 Mountain Bike is the flagship model of Trek’s popular Marlin lineup . This cross-country hardtail delivers serious performance at an accessible price point, making it the perfect choice for ambitious beginners and experienced riders alike .
Alpha Silver Aluminum Frame
The frame features Trek’s Alpha Silver Aluminum construction with a curved top tube and internal cable routing . The Marlin 8 2022 Mountain Bike includes rack and kickstand mounts, making it versatile enough for both trail riding and everyday use. The geometry yields a fairly slack 69.5° head angle (size L), striking a balance between climbing efficiency and downhill stability .
RockShox Judy Silver Solo Air Fork
Up front, you’ll find a RockShox Judy Silver Solo Air fork with 100mm of travel (80mm on XS frames) . The Marlin 8 2022 Mountain Bike features rebound adjustment and TurnKey hydraulic lockout, allowing you to fine-tune the suspension to your weight and terrain. Unlike the coil-spring forks found on lower-end Marlins, this air fork offers superior adjustability and trail feel .
12-Speed SRAM SX Eagle Drivetrain
The drivetrain is where this bike truly shines. A full SRAM SX Eagle groupset provides 12 speeds with an 11-50 tooth cassette . The Marlin 8 2022 Mountain Bike features a 30-tooth steel chainring and SRAM SX Eagle shifter and derailleur. The wide 11-50 range gives you the climbing gears you need for steep ascents while maintaining top-end speed for flats .
Tubeless-Ready Bontrager Kovee Wheels
The wheelset consists of Bontrager Kovee double-wall rims that are Tubeless Ready . The Marlin 8 2022 Mountain Bike rolls on Maxxis Ardent tires (26″ on XXS, 27.5″ on XS/S, or 29″ on M and up) featuring EXO puncture protection and a folding bead . The tubeless-ready setup allows you to ditch inner tubes for better traction, fewer flats, and lower rolling resistance .
Shimano MT200 Hydraulic Disc Brakes
Stopping power comes from Shimano MT200 hydraulic disc brakes with 180mm rotors front and rear (size-dependent) . The Marlin 8 2022 Mountain Bike delivers reliable, fade-free braking in all weather conditions. This is the same dependable hydraulic system found on bikes costing significantly more .
Bontrager Cockpit Components
The contact points are all Bontrager-branded: an Arvada saddle, alloy handlebars, and a Comp stem . The Marlin 8 2022 Mountain Bike uses a 31.6mm alloy seatpost and 31.8mm handlebars. The stem is Blendr-compatible, allowing clean integration of lights, computers, and phone mounts .
Frame Details and Mounting Points
The Marlin 8 2022 Mountain Bike features a standard threaded BSA bottom bracket (73mm) and straight 1-1/8″ head tube . Both wheels use QR axles (100x5mm front, 135x5mm rear) — not boost spacing. This is an important consideration for future upgrades. On the positive side, you get rack and kickstand mounts, plus internal cable routing that keeps the bike looking clean .
Sizing and Fit
Trek offers the Marlin 8 in seven sizes: XXS through XXL . Wheel size varies by frame:
The dual-wheel size approach ensures proper fit without toe overlap for smaller riders. Standover height ranges from 652mm (XXS) to 769mm (XXL) .
Weight
The complete bike weighs approximately 13.20 kg (29.1 lbs) . This is competitive for an aluminum hardtail at this price point.
Marlin 8 vs. Marlin 7 (2022)
The Marlin 8 2022 Mountain Bike sits above the Marlin 7 in Trek’s lineup. Key differences include:
- Air spring fork (Marlin 8) vs. coil spring (Marlin 7)
- SRAM SX Eagle 12-speed vs. Shimano Deore 10-speed
- Tubeless-ready rims and folding tires vs. standard rims with wire bead tires
- Higher-grade Bontrager Kovee wheels
Many riders find the 100 euro premium for the Marlin 8 well worth the upgraded components .

Why Choose the Marlin 8?
The Marlin 8 2022 Mountain Bike represents Trek’s effort to pack as much performance as possible into an entry-level price point . You get an air fork with lockout, a full 12-speed Eagle drivetrain, hydraulic disc brakes, and tubeless-ready wheels — features that were unheard of at this price just a few years ago.
The Judy Silver Solo Air fork is the standout component. Unlike the coil-spring forks on the Marlin 5, 6, and 7, this air fork allows precise tuning to your weight and riding style . The 100mm travel is ideal for cross-country and light trail use.
The 12-speed SRAM Eagle drivetrain gives you a massive 11-50 gear range. You’ll climb steep grades with the 50-tooth granny gear and still have speed on the flats. The single-ring design eliminates front derailleur complexity and dropped chains .
For riders ready to move beyond basic trail riding and into more serious cross-country or light enduro, the Marlin 8 2022 Mountain Bike delivers exceptional value.
