Shimano TL-SR22 Rear Sprocket Removal Tool

The TL-SR21 is probably the best track chain whip on the market; it does everything you would expect from a chain whip, it just does it a little better. It’s got a long handle, great for getting leverage on stubborn cogs tightened by repeated standing starts, with an ergonomic handle. A durable 1/8″ (Izumi made) chain in combination with a built in lock ring tool make this both long lasting and convenient to use.
