Re: Since when is 26" now 25"
See if you can find any markings on the rims that say EA-1. Regular 26x1 3/8 usually have an EA-3 rim if my memory is correct. The odd ones are the British EA-1. If you can't find any tires to fit them, I might be able to help you. In addition to working on new bicycles the past 28 years, I also do quite a bit of restoration work on the older ones for my customers. Good luck.
