Does anoyone have any information in regards to converting an S750 rear hub to freewheel? It is the same hub used on models from the s180 to the s750. All of these run on a chain drive, atleast up to the 2005 models. My question is about the hub itself, as the sprocket appears to be pressed into the hub. I have another rear hub from a boreem that is freewheel, but the sprocket bolts on to the hub. Since I have multiple s750's and s600's (and other models for parts yaay craigslist!) I wanted to convert the existing hubs rather than replace them. Any thoughts?
