Salsa Beargrease Carbon Fat Bike Frameset

The Beargrease is Salsa’s racing fat bike. After five successful years, the first production carbon fat bike has been redesigned to be better than ever. Increased tire capacity now allows the Beargrease to accommodate up to 4.6" tires on 100mm rims, and most 27.5 x 4" tires. The Beargrease’s influential ride and handling characteristics are preserved, while the chainstay length (440mm) remains unchanged.

• Rear spacing moves to 197mm, BUT strategic shaping of the stays create compatibility with "narrow" Q-factor fat bike cranks with offset rings. Heel clearance remains unchanged
• Expanded size range includes an XS option (14.5" seat tube) for smaller riders, and a slightly increased reach to all sizes to center around shorter 50–70mm length stems
• New Salsa Kingpin carbon fork features four sets of Three-Pack mounts plus lowrider mounts
• Full-length internal cable and housing tunnels ease builds and maintenance
• Rear rack-compatible with Alternator rack and Rack-Lock seat collar
