Chain Ring 

Hi Ron, thanks for creating the Chain Ring article. We already have chain rings covered at Crankset#Chainring, though, with some of the information (e.g. actuation ratio) covered in other articles such as derailleur gears. Thanks for pitching in though; I hope you stick around! Since your article duplicates the current one on chain rings, I've nominated it for speedy deletion - but please don't take this as a snub.
