CRT stands for colorado rapid tour, but it's hardly a touring bike as it barely accepts 700cx25 w/ fenders. We went to 650b and now I can get to 35mm tires if she wants to. She is running GB Cypres 32mm right now and love the tires (not any slower than when she rides her sporty Torelli Corsa Strada with 700x25c tires). The BB height is low. The BB drop for the CRT is 80mm, which makes for 247mm or so BB height with 650x32b tires on, a little hairy. We used 165mm Sugino cranks (with 110mm BB) and so far she hasn't stricken the pedals once. Using 35mm can raise the BB height maybe a hair more.

I bought a wheelset to tinker, without having a frame for them. I slapped them on my Surly KM with Fatty Rumpkins. The BB is way too low, but is only problematic when riding fixed. I'll be putting them on my really old Rockhopper as soon as I get some FMF brakes, but I doubt I'll room for knobbies at any point. Point is, they are totally worth it. The wheel size is perfect for commuting and after a loaded 130 mile day to my parent's place, it is pretty obvious that they are perfect for touring as well. Keep posting conversions. I think they are pretty fascinating. As is probably known, I’m a 650b newb. I bought a wheelset to tinker, without having a frame for them. I slapped them on my Surly KM with Fatty Rumpkins.
