Blackborow 1's flotation-maximizing components are all selected to provide best-in-class performance in this "wider" category of fatbike. Our 6066 aluminum Blackborow frame features Alternator Dropouts for setup versatility and emergency bailout gear options when things go wrong in the backcountry. The frame and fork use thru-axles for rock-solid wheel attachment and to boost tracking in rough terrain. Up front, the Bearpaw 150 fork features our Three-Pack mounting system allowing you to carry additional water or gear. Our component choices and frame design create correct MTB chainlines for both optimal performance and longer drivetrain component life. Important to note in this regard is our choice of the Surly OD crankset, which features the most outboard-positioned bearing design available, thereby distributing crankarm forces better and maximizing bearing life. Also worth noting is our choice of 100mm-wide Surly Clown Shoe rims clad with premium 26 x 4.8" folding bead Surly Lou tires. If you want the best in geared floatation, Blackborow 1 is your bike.

Blackborow Geometry
Blackborow's geometry is maximized for riding on tough, unpredictable surfaces and features incredible standover clearance. Designed specifically around massive 5"-width tires on 100mm rims, Blackborow provides extreme floatation in soft conditions like snow and sand, and also offers incredible traction and stability on any surface. Blackborow also features Alternator dropouts, which increase the bike's versatility and setup options, and allows for an adjustable wheelbase
6066-T6 Aluminum Tubeset
Top-shelf, double and triple-butted, heat-treated 6066 Aluminum tubing. Formed and shaped for optimized and appropriate stiffness, strength, and weight. Also offers excellent corrosion resistance
Dropped Toptube Layout
Seat tube lengths are increased one inch per size to facilitate a dropped toptube placement at the seat tube with a jump brace. Combined with a slightly higher bottom bracket (than Mukluk and Beargrease) this creates a bike with improved ground clearance and reduced pedal strikes when riding off-trail. This layout also results in extremely low standover heights
Versatile Fork Compatibility
Designed around Salsa's 51mm-offset Bearpaw and Makwa fork models. Blackborow is also fully compatible with RockShox Bluto suspension fork set at 100mm travel. This versatility covers everything from singletrack riding to multi-day snow races and beach expeditions
197 X 12mm Thru-Axle Rear Spacing
Equivalent to 190mm rear quick-release spacing, the 197 x 12 thru-axle design adds convenient hub catches that make wheel removal/installation easier & tool free; creates an appropriately secure and stiff wheel connection to the frame at this extreme hub width
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
Set-It-And-Forget-It Singlespeed Setup
The Alternator dropouts swinging design and set screws offer quick setup and tensioning. Vertical wheel entry means no re-tensioning or brake adjustments are necessary after a wheel change. Slip-free and creak-free performance
Replaceable/Serviceable Hardware
Alternator swing plates are all replaceable, and all the bolt hardware is standard-size metric socket head cap screws (also available in a replacement kit)
Shaped Chainstays & Seatstays
Provide maximum heel clearance in winter boots
PressFit 41 132mm Offset Bottom Bracket
Designed specifically for the Surly OD Moonlander crankset, which is the only production ~76mm chainline crankset to feature widest bearing placement, thereby increasing bottom bracket durability, optimized spindle strength, and bearing life
Direct Mount Front Derailleur Adaptor
Problem Solvers Direct Mount Adaptor adds flexibility to drivetrain setup and clean 1x builds
31.6mm Seatpost

Measurements based on:

  • a Salsa Bearpaw fork which is equivalent to RockShox Bluto 100mm at 25% sag.
  • a 26 x 4.8" tire measuring 760mm in diameter.
  • standover (P) measured vertically from the top of the toptube/brace intersection
Can I run 29-plus rims and tires on this frameset?
Yes, you can, 29+ and 26 x 5.0" tires have very similar diameters.
Can I run 4.0" tires on this bike?
The frame geometry is optimized around the diameter of a 5.0" tire, but can easily accept smaller tires. Keep in mind the difference in diameter of the smaller tire will lower the bottom bracket and decrease mechanical trail slightly, effectively quickening the steering feel.
Can I use a suspension fork on this frame?
Yes, this frame was designed and tested for use with a suspension fork with a static axle-to-crown length up to 511mm (typically 100mm of travel). Check the fork manufacturer's specifications to ensure the model and 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.
"On the short loop we were riding I liked how it handled through the twisties and it was confidence inspiring enough on the fast stuff that I came away from the ride thinking this was my favorite bike of the day." - July 2014
