I posted this a while ago (don't remember where) but never really got to work on it since I've been busy with other projects. I finally got a Victory RD to replace the cheap one it has now. I thought since I was going to try to get a matching RD for the Crankset I might as well find out what it is. So what is guys? I hate not knowing what it is . It rides beautifully and it fits like a glove.
