Mukluk C XT comes with the float of a 26” fat tire bike, the weight savings and efficiency of a carbon frame and fork, and adventure-ready mounts for all your ride necessities and accessories. Our Alternator 2.0 dropouts let you tune Mukluk’s ride to your liking, and the custom-studdable tires are perfect for dialing in your winter traction needs. With the performance of Shimano’s XT 12-speed drivetrain on board, this is a fat tire bike that can go to the distance.
High-Modulus Carbon Fiber Frame: This material offers the best blend of stiffness, vibration damping, durability, and weight savings
Mukluk Geometry: 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
Kingpin Deluxe Fork: Featuring full-carbon construction, the Kingpin Deluxe Fork is lightweight and durable, with an amazing array of accessory mounts to help you make the most of your Mukluk: Two sets of Three-Pack mounts on each fork leg for water bottles or Anything Cages / Lowrider rack mounts work with our Down Under front rack for a traditional touring setup / Internal dynamo hub wire routing keeps the front end looking clean
Alternator Dropouts V2.0: Mukluk Carbon is spec'd with a two-position fixed plate. The first of the two openings allows room for a 4.7" tire on a 70 mm rim and keeps chainstay length to 432 mm. The second position sets the wheel farther back, giving you options for larger rim and tire combinations. Adjustable dropout plates are available separately for single speed setups or finer adjustments
Front Wheel and Tire Options: The fork included with this frame works with the following wheel and tire combinations: 26 x 3.8–5.0” on up to a 100mm rim / 27.5 x 3.0–4.0” on an 80mm rim / 29 x 2.3–3.0” on a 50mm rim

Optimal 1x or 2x Drivetrain Design with Narrow Q-Factor Cranks: The Mukluk frame is 1x and 2x-compatible and designed for premium drivetrain performance while maintaining narrow fat bike crank arms for less knee stress: 197 mm symmetrical rear end for modern rim and tire fit / 100 mm threaded bottom bracket / Rider-friendly narrow Q-factor cranks / Designed for 1x or 2x drivetrains / Up to a 32t max chainring for 1x setups; 36/24t max for 2x setups
