Park Tool SR-12.2 Sprocket Remover/Chain Whip

The Park Tool SR-12.2 Sprocket Remover/Chain Whip is the updated version of Park Tool's workhorse cassette removal tool, now covering the full range of modern drivetrains from 7 through 13 speed. Whether you're working on a road bike running SRAM eTap AXS, a mountain bike with Shimano XTR, or a single-speed with a 3/32" cog, the SR-12.2 handles it without a second thought.

Construction is built for shop-level durability. The tool is heat-treated to resist bending and flexing under the considerable force cassette removal can require, and hardened pins keep the chain positively seated on the cog throughout the process. The long ergonomic molded handle — 14 inches total — gives you the leverage to break loose even a well-seized lockring without fighting the tool. An integrated 1" box-end wrench lets the SR-12.2 double as a driver for Park Tool's freewheel and cassette lockring tools, consolidating two functions into one handle.
