Beargrease Carbon 1 features the same premium high-modulus carbon frameset as its more expensive sibling, and delivers the same incredible ride quality, drivetrain efficiency, and front and rear thru-axle inspired tracking. The SRAM X1 drivetrain keeps you moving forward, while SRAM DB5 hydraulic brakes provide sure stopping power. Going fast requires good wheels, in this case Salsa Fat Conversion hubs paired with Surly Marge Lite rims, and clad with premium 120 tpi 45North Dillinger 26 x 3.8" folding tires. We love the shape and contact patch this rim/tire combination produces, and you'll see why as soon as you lean into a corner.

Beargrease - Endure Geometry
Designed as a racing fatbike with race agility. Features new geometry with a compact rear end that meets the demands of even the most aggressive racer, while still maintaining the proper weight distribution and stability required for navigating varied and difficult surface conditions. Maximized standover clearance aids dabbing, stopping, and restarting in tough trail conditions
Full Carbon Layup
Fatbike appropriate tube sizing and shaping. Large cross-sections for aesthetic but also frame stiffness and efficiency; results in precise handing, and efficient power transfer. Excellent corrosion resistance
Versatile Fork Compatibility
Designed around Salsa's 51mm-offset Makwa and Bearpaw fork models. Beargrease is also fully compatible with RockShox Bluto suspension fork set at 100mm travel
177 x 12mm Symmetrical Thru-Axle Rear Spacing
Equivalent to 170mm rear spacing, but thru-axle design adds convenient hub catches that make wheel removal/installation easier and tool-free; results in a stiffer wheel-frame connection optimizing power transfer; maintains proper chainline with the crankset. DT Swiss axle included
Tapered Headtube
Allows use of tapered and standard 1-1/8" forks
PressFit 41 121mm Bottom Bracket
The PressFit equivalent of a 100mm bottom bracket shell. This size is compatible with all 66mm chainline fatbike cranks (example: SRAM XX1, X9, X5, RaceFace Next SL, Turbine...). Paired with the 170/177mm spaced rear end this results in a drivetrain with proper alignment and performance
Shaped Chainstays & Seatstays
Double bend design provides maximum heel clearance in winter boots
Extra Wide Downtube
Large downtube acts as fender and helps keep the crud off your body
Direct Mount Front Derailleur Adaptor
Salsa Offset Direct Mount Adaptor adds flexibility to drivetrain setup, and allows clean 1x build
27.2mm Seatpost
For rider comfort
Full Length Cable Routing
Improved performance in poor conditions
Rear Tire Clearance
Designed for 26 x 4.0" tires on 82mm rims with full drivetrain. Compatible with 29+ tires on 50mm rims with full drivetrain. Compatible with 26 x 4.0" tires on 90/100mm rims. Tires measuring an actual 4.3 - 4.6" (regardless of rim width) will fit but will require drivetrain modification. Not compatible with tires larger than 26 x 4.6"
Waterbottle Bosses
Frame accepts 2 bottle cages (1 on SM)
Salsa Makwa Carbon Fork Included
Ultra light Carbon monocoque fork. Full-carbon tapered steerer tube. Oversized fatbike-appropriate blades. 15mm thru-axle. 74mm post mount
142 x 15mm Thru-Axle Fork Spacing
Equivalent to 135mm front spacing, but with convenient hub catches that make wheel removal/installation and tool-free; Improved front end stiffness, precise handling
Fork Tire Clearance
26 x 4.8" on 100mm rims. Compatible with all 26 x 4.0 - 5.0" tires and 29+ tires.

Measurements based on:

  • a Salsa Makwa fork which is equivalent to an a RockShox Bluto at 25% sag.
  • a 26 x 4.0" tire measuring 742mm in diameter.
  • 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).
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.
What should I do for a minor scuff on my carbon fiber frame?
First, check carefully that the scuff does not abrade completely through the layer of carbon. If it does not, we recommend coating the area with a thin, very light layer of clear finger nail polish.
"Most fatbikes are built for one thing—getting riders across snow or sand. In that regard, they're effective. But not many are fun to ride. They're heavy and slow turning. The Beargrease is different."

Traktion pur

"The Beargrease raises the fatbike bar for pure trail riding and racing."
-BIKE Magazine - March 2013
"...the Beargrease added a level of traction in super loose, steep switchbacks that is not found on standard mountain bikes. Eventually I rode to a high alpine area with large chunky rocks and loose conditions that the big tires added plenty of confidence, even where there was no trail.""
-BikeRumor - July 2013
"I got a chance to ride it a bit on singletrack, and really appreciated its weight savings over other fat bikes -- between that and its improved handling, it felt kind of like it was filled with helium."
-Bicycle Times - July 2013
"A fat bike isn't a guarantee that you'll be able to ride through all snow, and make it up every climb. Some snow is just too deep to pedal through. But a bike like the Beargrease is a guarantee that you'll at least be out riding in the winter through snow and having an awesome time doing it."
-Dirt Rag - January 2013
"Salsa's "lightest and fastest fatbike" is winning major snow-bike races this season." - March 2013
