2015 Beargrease: Two Flavors

Two years ago, we launched the Beargrease—our fatbike-racing platform—featuring an ultra-light aluminum frame and fork. A year later we launched Beargrease Carbon, which replaced the aluminum version. The debut of Beargrease Carbon saw a full carbon fiber construction paired with radically revised geometry to set a new benchmark for fatbikes. Beargrease Carbon didn’t just get lighter; it also showed just how well a fatbike could handle. For model year 2015, the aluminum Beargrease returns as our Beargrease 2 model.

2015 Beargrease 2...

The 2015 Beargrease 2 features the same geometry and sizing as Beargrease Carbon, packaged in a light and stiff 6066-T6 aluminum frame. This top-shelf heat-treated aluminum material offers better strength and fatigue life than 7000-series or 6061 frame tubing. Strategic butting and tube shaping also helps make the frame strong where it needs to be, stiff in the correct directions while also visually interesting.

Up front the Beargrease 2 comes in the same four sizes as its carbon counterparts (SM/15, MD/17, LG/19, XL/21) with two bottle mounts inside the front triangle. The aluminum frame features a ZS-tapered headtube set at 68.5 degrees and, like Beargrease Carbon, is designed for and sold with our 51mm offset thru-axle Makwa Carbon fatbike fork. The frame also will accommodate the aluminum Bearpaw fork featuring Three Pack boss mounts for Anything Cages for more adventurous endeavors, and the frame is also fully compatible with the RockShox Bluto suspension fork set to 100mm of travel.

Out back, the Beargrease 2 frame features the same PF41 x 121mm wide bottom bracket, BB height and super-short 440mm chainstays as the Beargrease Carbon model. This allows for fitment of most available 1x and 2x fatbike cranks designed for 100mm threaded shells, and has the capacity to easily fit the 26 x 4.0” tires the model was designed for use with. 

2015 Beargrease 2...

Like the carbon version, Beargrease 2 is designed to use a high direct mount, compact 2x, top-pull-only front derailleur fitted to a removable mounting bracket. This bracket can be omitted for 1x setups to further reduce weight and clean up the frame lines. The bracket (part number FS1327) is included with the frame, and is different than the bracket used with Beargrease Carbon (part number FS2324).  A 51mm I.S. brake mount is used in favor of the post-mount version found on the carbon version to simplify the finishing process of the frame, and maintains the ability to run 140mm rear brake rotors for the weight-conscious racer. A 10 x 170mm quick-release rear dropout spacing is also employed instead of a 12 x 177mm thru-axle. Driveline-wise, the 170mm rear end is identical to the 177mm thru-axle version, allowing for proper drivetrain alignment and optimal shifting performance, while clearing a 26 x 4” tire on a 82mm-wide rim.

Of course our premium Beargrease Carbon bikes also return in 2015 for those looking for the ultimate in fatbike racing performance.

2015 Beargrease Carbon XX1...

Lightweight and speed are the primary design drivers for our Beargrease fatbike family. For 2015 we take this a step further by spec’ing 70mm-width Whiskey No 9 Carbon rims on the top-of-the-line Beargrease Carbon XX1 model. Beargrease Carbon 1 and Beargrease 2 also receive a significant weight reduction by switching to 65mm-width Surly Marge Lite rims. This switch removes over a pound of rotating weight from the bike, which translates directly to increased speed.

2015 Beargrease Carbon 1...

In the past two years, the Beargrease has helped many racers reach the top step of the podium. We look forward to seeing that trend continue in 2015.

ABOUT THE AUTHOR

Pete Koski

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 hanger. Outside of work and riding, I enjoy kiteboarding, traveling, and watching hockey.

Are you’re front hubs convertible to 150mm or do you need to replace the rim or get new wheel for bluto?

Steve | July 28th, 2014

Honestly speaking, I wanted to get all excited about the aluminum Beargrease coming back because I’m not interested in Carbon, But then I saw the color! Why does everything have to look Dayglo bright these days? The same trend is happening in sportswear. Slime yellow and pink running shoes anyone? I know you can’t please all of the people and you gotta try something new but….  The original Beargrease was one nice looking bike compared to this.
Color palette is all over the place. And I’m sure it’s a fantastic ride but not for me in Toytown blue.

kevin | August 1st, 2014

What are the weights of the 2 carbon bear greases?

Dave | August 4th, 2014

I have to agree With Steve. I want a Beargrease 2 also and it meets everything I’m looking for, but….  That color!  Oof it’s bad. Give us an option on color and I’ll put in my pre-order tomorrow.

Jude | August 6th, 2014

That blue is lovely!

Brian | August 7th, 2014

I think the blue looks great. All of them look simple and classy.

Ray. | August 8th, 2014

Just get one and ride it.

Steve | August 11th, 2014

Brian, i think if you went out in a T-shirt in that blue color, you might look cool and fashionable, quite UNIQLO ( nothing wrong with that at all ) but I don’t think anyone would think you were ‘classy’.
Great that some folks like it though. I CAN see it looking good if it is loaded up with frame bags, say in a contrasting brown or some white…so there is hope! And Ray, i will definitely be buying one of the Salsa line up…and riding it…a lot!

Harris | August 13th, 2014

Great looking bikes. Could you explain a little more on the move to narrower rims? Did racers report that they didn’t need the extra footprint and would rather have a lighter set up? I’m afraid some will be reluctant to skinny down. That said, I applaud y’all for not just following the “wider is always better” forum bandwagon and thinking about what will actually make the bike ride the best it can for it’s purpose. Cheers!

What is the ETA on the beargrease2?

Kid Riemer | August 18th, 2014

Jay - My ETA sheet says December. Thanks for your interest.

Kid Riemer | August 18th, 2014

Harris - Why the move to narrower rims? There are a few different reasons behind this move.

First, we are seeing the Beargrease (and other fatbikes) being ridden and raced all year round, and not just in winter.

This is our racing fatbike and keeping the weight down is important…especially the rotating weight. Going with Whisky No 9 Carbon rims and Marge Lite rims with the subsequent narrower rim strip removes substantial rotating weight.

If this narrower rim created a crappy feeling tire surface we wouldn’t do it, but we find the tire shape of 4” tires like the 45NRTH Dillinger or Surly Nate to be ideal on this size rim. Essentially it creates a nice rounded profile that eliminates or drastically reduces the ‘auto steer’ sometimes felt from fatbike wheels.

Does it create slightly less flotation? Yes, but in snow racing you will drop your tire pressure to just a handful of psi and only miss a few mm’s of this width. Plus, many of the shorter “XC style” snow races will be on groomed tracks. For those taking on longer point to point races like the Arrowhead 135, we believe many will have a second wheelset with a wider rim and will be making a gametime decision on which wheelset to use.

That is our reasoning for spec’ing these narrower rims for 2015.

Harris | August 18th, 2014

^^^ thanks for that. Excellent response. Thanks for elaborating.

BDT | August 19th, 2014

When will the 2015 carbon Beargrease framesets be available, and is there any difference between them and the ‘14 other than color?  Great move on the wheels.  I have a 14 Muk 2 converted to a year round rider/race bike, stock frame, Beargrease carbon fork, carbon bars and seatpost, Race Face Next 1 x 10 drive train, etc.  I save my stock Darryl’s for the snow, and sand, and use Marge Lites, or even lighter Velocity Dually’s for racing.

Kid Riemer | August 25th, 2014

BDT - I don’t have Framesets availability info so will have to look into it. I believe that Beargrease Carbon 1 bikes have already begun shipping to dealers.

jesse | September 29th, 2014

can this set up accept a 29er wheels?

Kid Riemer | October 1st, 2014

Jesse - Yes, the Beargrease can fit 29 wheels. Keep it mind that those wheels most be built using the correct hub spacing. You can find all of that info on the Beargrease pages.

maros | October 7th, 2014

can i route dropper seat cable internally on beargrease carbon xxi frameset ? i mean using the optional front derailleur hole

Drew | November 8th, 2014

29” is interesting but any thoughts about a 27.5x3.0 tire and wheel setup?

Jai | November 25th, 2014

Is it possible to buy a Beargrease 2 frame only.
Price ?
I do not need the fork.

Kid Riemer | December 1st, 2014

Jai - The Beargrease 2 is available in Frameset Only, but not frame only. Of course you might be able to work with a dealer to take the fork out of the purchase.

Cindy | December 4th, 2014

Wondering if it is possible to switch out black marge lites for the white ones? We are trying to order 2 bikes and would like one blacked out to look a little different than the whited out one. I am guessing there will be no other frame colors? This is a great bike, love the component package you have put together, very well thought out! Thanks

Kid Riemer | December 5th, 2014

Cindy - I’m sorry but we can’t make that switch on our end. You can always have a custom wheel built though and your dealer can help arrange that.

Brandi Ackerman | December 5th, 2014

What are the weights?  I am a little surprised that it isn’t listed in the specs :P

maros vrabel | December 6th, 2014

My Beargrease Carbon xxi 2015 arrived a week ago. Weight is 11.06kg, excellent ! Although I know fatbike isn’t all about weigh.
The plan is put Bluto on it (arrived too) and considering KS Lev 27.2mm dropper to install. I will use this buie as all-year trail bike with only few rides during wintertime (snow).

Brandi Ackerman | December 7th, 2014

I’m going back and forth between the Beargrease Carbon 1 and the Rocky Mountain Blizzard.  Love the carbon, but undecided on a few other things. The Blizzard comes spec with the Bluto, and I’ve ridden RMB for years so I’m used to the shorter top tube (M 590 vs 605)... but I’m loving my roommates Salsa, he swears by Salsa (and the white is extra sweet!)  I’m not buying til Jan/Feb, so I guess i have time to grind it out in my head.  One thing is certain, everyone loves their Salsa!
