We know you can utilize your chain to take off your fixed gear cog, only once you take off your lockring. With the Union Foundry T0001 tool, you can use this tool over your lockring and utilize your chain (just as you do with your cog) to take off the lockring. No longer are you carrying around that lockring tool or busting your knuckles.
