New to me CB11, high mileage, so let's go through it and sort everything out. How hard could that be? Well, harder than it should when it comes to finding the right parts.
The Isa alloy sprocket it arrived with was pretty shot, much as expected, so not wanting to mess around I ordered a full chain and sprocket set from a UK source which included a Renthal hard anodised alloy rear socket. In a nutshell, it doesn't fit.
The Renthal sprocket has the correct 112mm bore with 6x M8 bolt mounting on a 160mm PCD, whereas the worn out Isa sprocket has 6 M10 bolts on a 156mm PCD.
Photos show the cush drive hub, adapter ring and Isa sprocket fitted.
Anyone have any clues to what I should order and where from?
The wheel has an Excel rim & stainless steel spokes which I'm not sure is standard either?
