The Stein Hyperhandle eliminates the need for ungainly chain whips that are used to secure the cassette freehub from turning while removing the lockring.

• Much faster than using a chain whip
• Can be used with the lockring driver in a bench vise using the flats 
• New model works with SRAM 10 tooth smallest cogs. The opposite side works with any 11 tooth smallest cog which is most common.
• The latest version accommodates 10 through 12 tooth cogs.  One side has the 11 and the other can be used with the 10 or the 12.
