I have just completed an R20 rebuild(link to photos below). I am dissatisfied with the handling of the RST Capa fork that I used and am thinking of replacing it with a fork from a Sun EZ Sport recumbent. I no longer have the stock fork so I cannot measure the length of the steerer tube.
Does anyone have a stock fork that they could measure for me? Or does someone know the the size of the steerer tube?
