Thanks for the offer Ed
I'm not keeping the Kastan to any sort of spec, just era correct mate with some nice parts from that year.
The CPR Rocket is a chainwheel
Very nice but, as I am using a spider, I need a chainring.
I was looking in a '94 mag with Pistol Pete doing a test and he was running the cranks I have using a Sugino ring, I think it is, so I may just opt for one of those or grab a Pro Neck as they were still around then too, like you say mate
I just thought there may have been some different, nice, rings about apart from chainwheels
