I'm in desperate need of help figuring out what size chainring I need to buy, and I've found some good candidates, but I don't know how to find out if they'll match up with the one I have. Where do I measure to find out if I need the 110mm or the 130mm, or maybe I need the 64mm! I just really am clueless. If you can help, let me know asap because the ring I have's already lost 3 teeth from wear... If it helps, the crank I have is a Sugino RD...
Need crank/chainring sizing help!!!

Here is an easy way to find the BCD -- http://www.sheldonbrown.com/gloss_bo-z.html#bcd
A quick intarweb search turns up 130 BCD.
