Blackborow 1’s flotation-maximizing components are all selected to provide best-in-class performance in this “wider” category of fatbike. Salsas 6066 aluminium 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 Salsas Three-Pack mounting system allowing you to carry additional water or gear. Their component choices and frame design create correct MTB chainlines for both optimal performance and longer drivetrain component life. If you want the best in geared floatation, Blackborow 1 is your bike.
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.
ZS44 Semi-Integrated Headset Standard
Compatible with tapered or straight 1-1/8" steerer forks.
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.
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.
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
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)
