New for 2013: Introducing Beargrease

New for 2013 is the Beargrease, our fat bike designed specifically to be a lightweight racer. We took the stable handling and geometry of our popular Mukluk frameset, and paired it with very stiff and light tubing, stripped it of extra features (and weight) and created a 5.2 lbs fat frameset (28.5 lbs for a stock Medium complete bike) that is perfectly suited for attacking events like the Arrowhead 135, the Simpson Desert Classic, or simply dominating your local weekend snow series.


At the heart of the Beargrease is the frameset. The frame uses the same 6000-series EV6 Extrolite tubing found on our Spearfish and Mamasita frames. The properties of this tubing, combined with intentional shaping, as well as single, double, and triple-butted profiles, combine to create a frame that tips the scales at 3.6 lbs. A tapered headtube and triple-butted downtube mate to shaped rear stays to create a stiffer frame than our Mukluk, offering more efficient power transfer. Ride compliance is deferred to the oversized, low pressure tires. Standard vertical dropouts are used in favor of our versatile Alternator dropouts to save weight, and because trail conditions typically vary so much that most fatbike racers favor a geared drivetrain. Frame, seat, and handlebar bags dominate the light and fast edurance scene these days, and the Beargrease follows this trend; rack and fenders mounts are ommited to save precious grams. We didn't skimp on bottle mounts, knowing that local weekend racers prefer bottles for the shorter sprint events. Each frame features two bottle mounts in the front triangle (only one on XS). Beargrease receives a black anodized finish instead of paint, which also nets over 100g in weight savings.

The fork was an integral part in achieving the Beargrease design. Because ride compliance was less of a design factor for a fork intended to be used with large, low-presure tires, we are able to capitailze on what makes aluminum a great material for bikes: large diameter tubes that are very stiff and light. The heat treated 7000-series fork features a custom-designed one-piece tapered steerer tube and huge D-shaped, butted and tapered blades in a fully-welded construction (no gluing or bonding). This creates a very strong and light-weight fork, weighing in at just 720 grams (uncut), a full pound lighter than our feature-laden Enabler fork. The Beargrease fork uses the same 135mm spacing, front I.S. brake pattern, and 15.25mm (rear) disc/hub offset as the Enabler, and like the frame, will come in a Speedy Black Anodized finish. The fork is included with the Beargrease frameset, but will also be available seperately as well.

2013 Beargrease: Complete Bike MSRP $2999; Frameset Only MSRP $999


The Beargrease frame features the same low and stable geometry as our 2012 Mukluks. This makes riding in soft or loose conditions at both slow and fast speeds a little more comfortable (less twitchy), and the low standover height makes dabbing, dismounting, and re-starting easier. The only significant change we made was to reduce the headtube length a bit, and combined with the ZS tapered headset stack, puts the bars about 20mm lower, comparatively. This allows for a more aggressive riding position for those looking to hammer. For those who prefered the more upright position of the 2011 or 2012 Mukluk, 20mm of spacers and/or one of our higher angle rise stems does the trick.

Regarding Spec

The complete bike spec, like the frameset design, was chosen with the intent of yielding a lightweight and efficient fat bike. The wheels utilize Salsa Mukluk 2 hubs laced to custom color-matched Surly Holy Rolling Darryl rims and 120tpi folding-bead 45NRTH Husker Du tires. A 160mm front/140mm rear set of Avid Elixir 5 hydraulic brakes offer up a lighter setup than cable-pull discs brakes, and the DOT fluid running through the lines is rated well below 0F. The drivetrain is a mix of SRAM 10-speed X0 and X7 components. The crankset/bottom bracket featured on the Beargrease is a new and exciting product from our friends over at Ethirteen. It's a totally new, redesigned crank arm with nice look, a stiff feel, and a lightweight design thanks to their innovative spindle design. It also features new and improved BB cups/seals/bearings for better bearing life. Perhaps the coolest feature of the crankset though, is an exclusive 64/104mm BCD chainring spider co-designed with Salsa, that improves the alignment of the chainrings to the rear cassette, creating better shifting performance and eliminating tire/chain intereference (82mm rims/3.8" tires). The Beargease cockpit is made up of our Pro Moto 2 components and our new clamp-on Backcountry grips. The frame features full-length housing and under-the-toptube cable routing.

FAQ & Compatability

Lastly, here are some answers to questions you may have:

  • Frameset includes both frame and Beargrease fork
  • Beargrease fork will be sold seperately for those wanting to add it to a 2013 Mukluk, or other tapered compatible frame
  • Headset is ZS tapered (same as Spearfish) S.H.I.S. = ZS44/28.6 | ZS56/40
  • Post/Collar = 27.2mm/32mm
  • Front Derailleur type is high-direct mount, top-pull, and mounts via Problem Solvers adaptor
  • Frame fits 26 x 3.8" tires on 100mm rims, but drivetrain modifications may need to be made
  • Frame fits Surly BFL on both 80 and100mm rims, but drivetrain modifications must be made
  • Frame DOES NOT fit Surly Lou tires on any rim. Those things are HUGE!
  • Frame DOES NOT fit Surly 29+ Knard/Rabbit Hole wheels
  • Fork clears all 3.8"/4.8"/29+ tires on 65/80/100mm combos currently known. (NOTE: Surly Bud on 100mm rim requires low pressure to squeeze past the caliper)
  • Similarly sized Mukluk frame bags will fit on the Beargrease

We're stoked on the Beargrease as another step forward in the evolution of fatbikes, and hope you are too.

Hi, I'm Pete and I am a product development engineer for Salsa. I like all kinds of riding from commuting to dirt jumping. I think flat pedals make you a better bike handler, that the thru-axle is vastly superior to the quick-release for off-road applications, and that moving through the world on bicycle allows one to see things they might not otherwise. I suffer daily from hunger-induced anger, also known as [i]hanger[/i]. Outside of work and riding, I enjoy kiteboarding, traveling, and watching hockey.

so… Lou in the front on a Clown Shoe.

and I can run a BFL on a Clown Shoe in the back, but with drivetrain mods…

I wonder if I can combine the Salsa 135mm adapter with an Alfine in some creative way. That would move the chainline outboard considerably.

“paired it with very stiff and light tubing, stripped it of extra features (and weight) and created a 5.2 lbs fat frameset”

“The properties of this tubing, combined with intentional shaping, as well as single, double, and triple-butted profiles, combine to create a frame that tips the scales at 3.6 lbs.”

... and a medium Mukluk Ti is 4.3 lbs, so how much does the Beargrease (Med) frame really weigh?


Gnat | August 24th, 2012

Thanks all.

Robert, not sure I understand your question but I think it lies in the definition of frameset vs frame only.

The Beargrease frameset which consists of a frame and fork is 5.2 lbs. Subtract the fork weight listed of 720 grams (1.58lbs) and you get 3.6lbs as stated.

I saw this at EuroBike on Friday and I have to say, it’s the first 26” based, mass-produced Fat Bike that I’ve had ANY interest in. It’s really nice! Glad to see that the Salsa sense of humor isn’t lost (ala Baby Blue rims, etc.). Good luck with it!

I was racing my Muk 3 last weekend at (WORS) Treadfest and this fellow racer told me about the Beargrease. I went home afterwards and looked on-line and immediately started to drool. I did fairly well considering my 2012 Muk 3 tips the scale at 34 lbs. I will be buying a Beargrease for the weight and racing, as well as most of my rides are under fifty miles.

I just started seeing these fat tire bikes in my area and I am really interested in them. I would use it to commute to work in the winter but my fear is that the salt that is on the roads would rust the bike and components.

Just wondering about the durability under these conditions.

Have you supplied Cosmic already? Just wonder as I can not reach their website.

Or can you recommend an US dealer shipping overseas?

Because Paul
The Mukluks do and I was going to have a second lighter 29er wheel set to ride in the summer. But, thanks for pointing out the obvious on the 26” x3.8

Odd Andreassen - Contact .(JavaScript must be enabled to view this email address) and they will try to direct you toward a dealer that might be able to help

Claude - Salted winter roads can obviously due some harm to the components just as they will with any bike. Personally I’ve found that taking care of the chain is the main task you need to worry about. I’ve also found that keeping the bike ‘cold’ helps a lot, meaning try to avoid freezing/thawing cycles if possible by keeping the bike outdoors or in a cold location (unheated garage). Remember, the frame and fork of the Beargrease are aluminum so you don’t need to worry about rust there.

Frank - Contact .(JavaScript must be enabled to view this email address) for help finding a dealer.

Mike - Yes, the bike will fit 29’er wheels. Remember you will need to build them with 135mm and 170mm hubs.

Chris March - In the USA the Beargrease is MSRP $2999.

Ed - We spec a long cage rear derailleur.

Thanks for your interest in the Beargrease folks. Remember we also have the Mukluk in our line. -Kid

Love you guys at Salsa to bits!
Gnat/Kid you guys are GREAT at answering questions! Thanks for being so prompt,honest and forward. Along with Salsa being Innovative,quality,light weight,Where do I stop?
***I don’t want to stop talking about Salsa!
  I’m offering Gnat&Kid; to help out while announcing at the many races I attend here in Alberta and British Columbia to promote Salsa even more as the bike of choice for racers and pleasure. Soon announcing gigs in Turin,Italy - India(maybe?) - South Africa - and USA, life is starting to get busier with announcing cycling races.
Any chance of working on a even more light weight bike than the ‘BearGrease’ and that comes without offense of any kind; THIS IS ONE mean “LightWeight” winner of a bike; just wanting to push the envelope if I’m to show it to so many people and carry it over mtn passes in training.I am finally, registering my very own little cycling team of kids whom ALL UniCycle minimum 2 yrs. “Each” of them, only wishes to become World Champions. I told them about just doing your best; and they still say “World’s sounds better!”
Love ya’s!Gnat and Kid > Keep up the GREAT GREAT work eh!?
*** NEED I say more! LOVE to use your bikes and show them! Wow!!!!

Hey guys love the Beargrease, it really is an awesome looking fat bike with great colour coding. One question though, is the wheelset available for separate purchase? I have a 2012 Blue Mukluk and the Beargrease wheelset would look awesome on it, just something about those blue rims…

Kid Riemer

Kid Riemer | November 26th, 2012

I’m the Mike that posted on Nov 9.  I got to pick up my Beargrease on the 16th, and I just want to say I really love it.  So far it has outperformed every one of my expectations.  It might have only one drawback.  That is, I enjoy being in my own little world while riding my road bike, but now I have to speak to others because this bike gets a lot of cool comments every time I ride!  Everybody from young to old notices the wheels.
Great job designing something fun and unique.

Can the 135 adaptor for the Mukluk be used on the rear?

Kid Riemer

Kid Riemer | January 7th, 2013

Miles: Yes, you can use our 135 Space Out Adaptor in order to use a 135mm rear hub on the Beargrease. Please remember that your rear wheel needs to be built ‘Pugsley style’ to make this work, meaning it needs a 17.5mm offset.

And I’ll also add that while this setup works, it is not as ideal as using a 170mm rear hub.

Steve Jones | February 9th, 2013

Is that fillet brazing I see where the tubes are joined? Don’t recall seeing that on an aluminum bike, usually on fancy steel frames. Any comment on this? it looks neat!

Lightweight or not. You ought to have kept water bottle mounts ( ONE on the XS! good grief, come ON guys! on a bike that costs this much that’s just…..).
The lack of a rack mount I’ll half forgive you for. But it doesn’t help your customers make an easy choice. For example I NEED alternators ( for single speed) and mounts but i want the anodized finish, clean welds, colors and Husker DU’s. So I’m out of luck and whichever option I choose I’m having to compromise and can’t get that combo. Same with the purple black frame, (which I like) but can’t get a complete with that so have the expense of having to buy all the parts separately.
What to do? What to do?
This does look like a great bike but if only you had put alternators on it….

Hey, at least i didn’t mention the Rohloff word..oops now I’ve done it. Just kidding!

Paul rotkis | February 9th, 2013

Please Salsa, make a frame for next year that will take real fat tires on clown shoes I.e Lou and Bud. (Husker dus are great for racers and skinny cats, but offer no floatation and perform poorly in loose and deeper snow, thus becoming Huskerdonts.)

I wanted to ride in the snow and my mt bike with studs and couldn’t ride on the trail where the snow machines go. So I tested the beargrease out and I couldn’t believe how fast it was. My perception was that I would have to overcome a lot of torque related to the size of the tires. It was smooth, the ice was easy. The six inches of snow I could ride through as well. I ended up buying it with some poagies. I love my new bike, the look, the ride. Still can’t believe how light it is. I am sold, proud to be the owner of a fat bike.

Love my Beargrease so much. Thanks guys. I can’t wait to go carbon next. I was just at the Grand Canyon with the Grease on the back of my family minivan.
