Just wanted to pass on what a big help Chris Baker at Z1 Enterprises was regarding my 630 to 530 chain/sprocket conversion. For less than a decent 630 chain I have ordered a new front/rear sprockets, and a very nice RK X style 530 chain. They don't carry the 47t rear I needed (according to the formula), but with Chris' recommendation I am staying very, very close to my factory 2.6:1 ratio. Good people at Z1.
