I love this tool.Aside from having to do something drastic this tool really is all that you would need for regular rides on your Fixie or Single speed.I have a short piece of chain pinned on as a small cog whip, the lockring part works great, the lug nut tool fits my track nuts perfectly and the alan key and bolt step down fit my chain tensioners.I think that bottle openers on every bike related tool is stupid as hell but this has one too.One note:If you attach the chain to use as a whip in the provided pin hole you wont be able to use your badly needed bottle opener.So Sorry.....It also comes with wing nuts to secure it nicely to a water bottle mount.Nice little Multi tool for the money.
