    Considering All City Nature Boy ACE: do eccentric bottom brackets suck?

    The new Nature Boy looks right up my alley, but I have one major concern: it has an eccentric bottom bracket as a chain tensioning device. The Nature Boy's EBB is a PF30 shell with an EBB mounted within. I can't seem to get a clear consensus on this type of setup: some say it's impossible to set up and that it will creak immediately. Others say that it it set-it-and-forget-it simple and reliable. Also, it seems like some manufacturers' EBBs are good while others are terrible.

    Has anyone here ever had a bike with an EBB? What did you think?

    On single speed bikes I thought all you needed was to pull the wheel back to tension the chain. Is that EBB floating on springs or what?
