My Severn Valley frame has Cyclo rear drop-outs. All well and good as that is a nice Birmingham maker and all that. I am about to start building it up and have got to the "discovering all the irritating little bits you don't have stage."
On the list is a pair of those long screws that thread through the rear drop-outs and set the rear axle position. I know that the 3mm Campag ones are available, but is the Cyclo likely to be the same thread?
I told you it was esoteric!
