Hi all, thank you so much for the replies. To answer some questions and provide additional info:
Joe you are correct: 55 Cheviot, 54.5 Homer. I had thought about getting a purple Apaloosa when they went on sale last year, but after talking to Rivendell, realized that the Homer was a better fit for my use case. Once I saw they were offering the butternut/mustard/classic Datsun color, I was in.
It's tough picking a size without getting a chance to try the bikes first, so I utilized the PBH sizing Riv recommends--but I do think the frame is a bit large, all things considered. Standover does work for me, so I'm hopeful I can get it to work. I already have the seat forward on the rails, btw. I will swap the stem this weekend and see how that goes. Next would be handlebars, going shorter reach and also narrower. (sounds like I shouldn't be afraid of going even shorter.) I'm currently running a 46cm Noodle, which feels wide in addition to long. When I swapped bars on the Breezer, I went with shorter AND narrower, going from 44-42, and both of those changes helped a lot. . Oh, and Chris, thanks for reminding me about handlebar diameter. I forgot about the different standards. I think between bar and stem, I can make it work for me. This bike is beautiful (way more than my pic), and I put a lot of thought into the build. In retrospect, I would have gotten the bike fit first, with the Breezer, to get all the #s I need.
Also, thank you Liz for the detailed fit info and the suggestion regarding quill/threadless adapters for the bike fit. I was wondering how that would work.
