So I went to both WEB and DBC today and ended up just getting my two Peugeots serviced rather than having them converted to single-speed (was going to end up costing a fortune). Looks like I will probably end up just purchasing another bike, which is fine. These are some great bike shops! scattered73, I will probably end up checking out HBC sometime in the near future.
I was also impressed by the selection of single-speed bikes at DBC. Too bad I can't have the bikes back today. It's freakin' beautiful outside.
