Ever break a chain whip trying to get your cog off, or bash your knuckles into the spokes when the chain slipped?  Well that happened to us a lot and we got tired of it.  So we talked to the J. A. Stein Company about it and they came up with the Un-Fixie wrench.  This tool will remove 15t through 20t track cogs.  It can be locked on to the hub for really tough cogs.  Its long enough to give you plenty of leverage, but it will still fit in a Craftsman tool box.  We've been using one of these in the shop for quite a while and have been very happy with it.  We are excited to be able to offer them to everyone else.

 

Never fight with a broken chain whip or smash your knuckles again.
