The first part of many has arrived, I've sourced some almost original spec Forks from this very forum, these are two years too modern (Rock Shox 2002 SID SL), but pretty close. I've read that some of them suffered from excessive flex, but we shall see! They are in pretty good shape.
I've opted for a Cane Creek Forty as the headset. I'd have liked to get something a bit fancier, at £30, I think they are a pretty good choice for the money, and I dont need to worry about the crown race seat diameter if i swap forks with another in my collection. I should now at least be able to do a loose assembly to get an idea of how it's going to look.
