White walls or black walls, old fashioned bike wheels are getting hard to find. Everything has gone over to metric and the 27 inch and 26 inch tyres of yesteryear are hard to find now. That’s a problem for people like me with little legs. I had 26 inch wheels and when I had my bike rebuilt they put in 700c’s which are ever so slightly larger. That resulted in my saddle being slightly too high. I always used to lay my bike on the floor to get over the frame, but once I stand it up I can’t get on the saddle. I want to lower that, but the bolt had seized… Might try finding a shopper bike!
