Lets take that discussion over to the
Performance Exhaust thread
I admit I didn't get much info on it as I was more interested in information about the progressive shock but I've emailed Ryan for details and will post in that thread once I get more info.
Re Progressive Shock: inseam challenged folk would be looking at about a 1" increase installing the progressive shock without also installing a lowering link. So....looks like no progressive shock for me.
