as it turns out, couldn't find nos at a reasonable price ($200+ for a brake/lever set isn't too bad, but isn't very good when you just want one brake), HOWEVER a guy at my lbs is-- get this-- selling me a white caliper off of HIS OWN BIKE to help me out!! I have to call him tomorrow for a price, but i've gotta say that's incredibly awesome. he said it's in good condition, which is totally icing on the cake.
Srsly, from this point on, if anyone in any part of philadelphia needs a part or work done, i'm sending them straight to chaz and them at
bicycle stable.
