Yeah, That's what I was going to do. It isn't going to be a fixie.. just for riding around my town, to the supermarket etc. And if the chain does get too loose I'll bolt on a tensioner until maybe it eventually gets loose enough to fit another half-link. I'd really rather not have a tensioner though. It sucks to finally remove that clunky dérailleur just put something on that looks just like a dérailleur again.

Also, Thanks AEO,
I read about Sheldon's skewer method, but to be honest I would still be nervous about that. I'm afraid I would end up on that "MS paint your mishaps" thread..

And, wroomroomopps, Of course magic gears work. It's bloody magic, mate.
