Thanks for the responses guys, and the nice pic Fred. Yes, should have mentioned it's 110 BCD. I kept thinking it was 130 from measuring it a good while ago, but just checked and it's 110. Harris Cyclery has a Origin8 BMX chainring that fits both 110 & 130. Guess that would be good if you screwed up the measurement. They also have a Sugino 110mm no ramps ring. I did come across the Surly and was considering it as an option. The Harris site is nice with all the articles. I will at some point replace the cantilever brakes also. Any ideas on that?............. Thanks again for the input.
