Pedro's Cog Wrench

If you're tired of dealing with the frustration and bruised knuckles from slipped chain whips, Pedro's Cog Wrench is the answer. It securely holds 11 or 12 tooth cogs while a cassette tool fits in the center of the wrench. This system provides good purchase and leverage for loosening cassettes. A tubular handle with a rubber grip ensures comfort and security when using leverage, while heat treated construction guarantees strength.
