Mukluk 2 Suspension brings the same advantages of the RockShox Bluto suspension fork, but combines them with our 6066 aluminum frame. Fatbikes are mountain bikes, and the addition of the Bluto fork really highlights that fact on the trail. Alternator Dropouts continue to offer versatility in setup and SOL-in-the-backcountry emergency bailout gear capability. A solid SRAM drivetrain keeps you moving forward while SRAM Guide R brakes handle your braking needs. And just as on the premium titanium version, the wheelset is a solid package of Salsa Fat Conversion hubs mounted to Holy Rolling Darryl rims clad with Surly 26 x 3.8" 120 tpi Nate tires. We find this to provide the perfect balance of flotation and traction for on- and off-trail exploration. Also note that we also offer the Mukluk 2 as a rigid frameset, including the Salsa Bearpaw 150 fork, in Sparkly Green.

Mukluk Geometry
Designed as a blend between fatbike and mountain bike. Mukluk provides floatation in soft conditions like snow and sand, but also incredible traction and stability for singletrack dirt trail conditions. Geometry provides generous standover clearance facilitating dabbing, restarts, dismounts and re-mounts. Alternator dropouts facilitate adjustable geometry for optimal handling for the given terrain
6066 Aluminum Tubeset
Top-shelf, double-butted, heat-treated 6066 Aluminum tubing optimized for strength and weight. Excellent corrosion resistance
ZS44 Semi-Integrated Headset Standard
Compatible with tapered or straight 1-1/8" steerer forks
Versatile Fork Compatibility
Designed around Salsa's 51mm-offset Bearpaw and Makwa fork models. Mukluk is also fully compatible with RockShox Bluto suspension fork set at 100mm travel. This versatility covers everything from singletrack ripping to snow riding and multi-day beach exploration
Ovalized Downtube
Improves handling and front triangle stiffness
170mm Rear Spacing
Results in a stronger, symmetrical rear wheel while maintaining proper chainline with 100mm bottom bracket for optimal drivetrain performance
Alternator Dropouts
Allows wheelbase changes and chain tensioning. No disc brake adjustment needed when setting wheel position. Vertical dropout for easy wheel installation/removal. Proven in the NUE Series and in the Tour Divide. Alternator Dropouts Instructions
Alternator Plate Options
Multiple options: Quick-Release, Thru-Axle, QR & Thru-Axle Singlespeed, QR with Fender Mounts, and Rohloff OEM2
Set-It-And-Forget-It Singlespeed Setup

Adjustable Ride Characteristics
Using the Alternator dropouts, geared riders can fine-tune the ride characteristics of their bike by adjusting chainstay length and overall wheelbase to be quick and nimble, or longer and more stable
Replaceable/Serviceable Hardware
Alternator swing plates (Geared, Singlespeed, Thru-Axle, Rohloff) are all replaceable, and all the bolt hardware is standard-size metric socket head cap screws (also available in a replacement kit)

Measurements based on:

  • standover (P) measured vertically to top of toptube from a position 50mm forward of BB center
Can I run 27.5" (650b) rims and tires on this frameset?
No, doing so will absolutely ruin the performance of the bike by throwing off all our carefully selected frame geometry.
Can I run 29-plus rims and tires on this frameset?
Yes, you can, but keep in mind that the frame geometry will be affected slightly. The bottom bracket height will increase and also the length of fork trail will increase.
Can I run 5" tires on this bike?
The fork is designed to accept up to 5" fatbike tires mounted on 100mm-width rims. The rear end of the bike is optimally designed for use with 3.8" fatbike tires mounted on 80mm rims. The rear end will accept 100mm-width rims with 3.8" tires, or 80mm rims with 4.5" tires, but this may require drivetrain modification. The frame will not accept a 5" fatbike tire.
Can I use a suspension fork on this frame?
Yes, this frame was designed and tested for use with a suspension fork with an axle-to-crown length up to 511mm (typically 100mm of travel). Check the fork manufacturer's specifications to ensure the model & travel combination you intend to use is equal to or less than this length. Using a longer length fork will void the frame warranty and could result in frame failure. Forks with 51mm offset are strongly recommended, but 45mm offset is also acceptable (increases mechanical trail by 6mm).
Do you offer touch-up paint?
No, we do not offer touch up paint. Hobby shops or automotive stores are excellent places to find paint. We suggest you test the paint on a scrap piece of metal before using it on your frame.
How do I take care of the Alternator dropouts?
Periodically, we recommend that you remove the bolts and clean the dirt and grime off the hardware and the frame surfaces. Then, lightly regrease the threaded parts and re-assemble.
I crashed and dented (or cracked) my frame. Is it safe to ride?
Stop riding your frame immediately and take it to the nearest Salsa authorized dealer for inspection. A dented or cracked tube represents a structural weakening of the frame, and is a safety risk.
"I took out the Muk 2 to check out the Bluto some more and found the bike very capable on the trail. I overcooked a corner and blasted through some scree but the Bluto-equipped front end smoothed out my mistake instead of sending me flying. Kudos, Bluto, kudos!" - July 2014
"The Ti Mukluk receives a similar half painted look as the rest of Salsa's bikes with a clearcoat covering the entire bike. Raw Ti is beautiful in its own right, but I have to admit that the painted Ti bikes were beautiful in person."
-BikeRumor - July 2013
"In motion, the Mukluk 2 is a contrast of attributes. It lumbers along undaunted in 6" of snow, but when it hits open trail, it rails with authority reminding you that this is no saucer sled, this is a bike with proper mountain bike DNA. At times I've found myself mid turn, driving hard, tires growling, not yielding an inch. The traction is astounding on dry trails, reminding me that this bike is not just for snowy days, although that is were it is most fun to ride."
-Expedition Portal - March 2013 Previous
"The Mukluk 2 somehow has become my defacto mountain bike. I've come to believe that this fat bike is what all other mountain bikes, really want to be when they grow up. This is truly a mountain bike for real." - June 2012
"I suggest we begin thinking of these bikes as "all-terrain" and not merely for snow."
-GearJunkie - January 2012
"The Mukluk specifically is a great platform for exploratory outings which may be uncharted areas, or otherwise may take you through bits of trail that are difficult to impossible to ride on a "normal" 29″er. It is a stable handling rig and those tires eat up terrain that would stop a typical 29″er in its tracks. Deeper grounds, sand, mud, forest floor debris, and deep rock are easy to traverse on the Mukluk and bring rides into focus that you may never have considered before."
