A good adventure partner is reliable, covers ground at your pace, helps shoulder the load, and gives you the confidence to keep going when the trail looks tough (or disappears entirely). Mukluk checks all the boxes with Alternator dropouts, a lightweight aluminum frame, plenty of gear mounts, and stable geometry.
6066-T6 Aluminum Frame
Top-shelf, double and triple-butted, heat-treated 6066-T6 aluminum tubing is used throughout the frame. This 6000-series aluminum has better strength and fatigue characteristics than 6061 and 7000-series aluminums, allowing for a stronger and lighter overall frame. Additionally, the tubing is strategically shaped and formed for additional stiffness and strength optimization in key stress areas.
Mukluk’s geometry works extremely well in all conditions and use cases, whether it's riding groomed singletrack at your local trail, exploring a coastline, or embarking across the wild frozen expanses of Alaska. We use the shortest chainstays possible with a headtube angle and fork offset that place the rider’s center of gravity farther back. This combination of front and rear center is key to getting a fat bike that is stable, steers well in loose conditions, and still feels nimble despite the massive wheels and tires. A low bottom bracket also keeps the rider’s center of gravity low and makes dabbing, dismounting, and remounting easier.
26 x 4.6” Wheel & Tire Size
Mukluk rolls on 26 x 4.6" tires on 80 mm rims. This huge tire delivers massive traction, stability, and optimum floatation on soft surfaces such as ungroomed snow or loose sand.
This carbon fork features a 150 x 15 mm thru-axle that boosts stiffness and improves steering precision. The fork also features our Three-Pack mounts for accessorizing with Anything Cages or water bottle cages
Alternator Dropouts V1.0
The Alternator dropout delivers incredible drivetrain versatility. Run singlespeed or geared, QR or thru-axle, freehub or Rohloff. Set the Alternator dropouts all the way forward for a shorter wheelbase that results in quick and nimble handling, or set back for more stability—the power is yours.
Full-Length Internal Housing Cable Routing
Full-length housing improves shifting performance in poor conditions and increases use time between maintenance intervals.
Stealth Dropper Post Routing
Compatible with 31.6 mm dropper posts for a true trail bike experience.
Multiple Accessory Frame Mounts
2 water bottle mounts inside frame triangle. 1 accessory mount on under-side of down tube.
