One other question. I see that there was one hub that was 126 spacing but had a freehub, the Shimano 1055. It was limited to 7sp, but is it really? Couldn't I put 8 or 9 of a 10 or 11 cassette on it and then use the matching brifter and just set the limit screws? I would do this because the later brifters work better than the early ones. I rented an 11sp 105 equipped bike and was impressed by how well it worked, better than my Chorus 10 on my main ride. Anyway, is it possible? I'm not necessarily going to do it. This bike is for my adult daughter who saw it in our basement and wondered why nobody ever used it, and thinks it's cute. She didn't like the feel of the brake hoods though and if I were to replace that, well that just is the start of that slippery slope,
