2024 Salsa Mukluk microSHIFT ADVENT X

Mukluk microSHIFT ADVENT X is our aluminum frame fat tire bike that begs you to load it up and roll out to your favorite places, no matter what type of terrain you encounter along the way. Massive tires (and even bigger tire clearance) let you maximize float on soft surfaces. Ample frame and fork mounts give you choices when packing your adventure necessities: extra water, fuel, snacks, sleeping gear-everything has a place on Mukluk. Adjustable Alternator 1.0 dropouts and custom-studdable tires let you adapt the bike to your riding conditions. The microSHIFT ADVENT X 10-speed drivetrain is a reliable partner for those rides that venture far from home.

Alternator Dropouts

Tune your ride characteristics and switch to single speed with ease. Our swappable dropout plates allow for multiple drivetrain options.

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 GEOMETRY

Mukluks 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 riders 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 riders 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

BEARPAW FORK

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.
