Hope you do not blow your knees out BigChief.
I have two 23s now. One complete bike and one very nice frame and parts. I am planning to build one of them for my brother who is a little over 6 foot tall and has a rails to trails right behind his house and plenty of cycling opportunities near his house. Me, I am not quite 5-11 (my aviation medical say 5-11) but I think I have shrunk. Anyways, when I get on a 23 inch frame if I dismount that top tube is too close for comfort if you ask me. I used to look for 23s and now I look for 21s and want a 19 step through. But the 23 inch bikes I have rescued will find useful homes in due time.
I have my MB3, the Dunelt and my Guerciotto all apart in the basement shop, hope the parts do not get mixed up! Could make for a Johnny Cash song---- and then the steering of my Jeep need to be replaced, so I am kinda underwater on mechanical projects. Could end up looking like this.
