I am talking to a manufacturer about possibly making a 415 or 428 chain/sprocket kit for the RC 390. He said that we would need to get at least 20 people to buy in to justify the work and that the 415 kit could take a few months to produce. They could possibly get a 428 kit made up sooner. I told him I would post here and gauge interest.
If you guys dont have experience with these kits, it offers a pretty massive weight saving on rotating mass over the stock setup. Pretty much anyone that races a lightweight bike uses a kit like this on their bike as long as they are available.
