It needs new wheels and is spec'd for 27"ers. I would like to go with 700c wheels if possible, but my only reasons are these: better rims choices availible, more tires(and types of tires, haven't seen many 27" folders) availble, and added fender clearance. Clearance may not be a big issue, but it would be an advantage. The problem is that I don't know if the brakes will line up. For any retro-tech specialists, the ones I have are mid 80s XT. Anyone try this conversion with the frame I have? Any predictions as to the fit? I know posts are brazed in different positions depending on manufacturer and modle, what should I expect? The frame is in the mail, so I have to wait a week at least before I can stick a wheel in the dropouts and test it.

Here's the next part of the question: If I am forced to go with 27s, what should I be prepared to deal with? Anyone know a great 27" rim? I can definitly find tires, the choices are just limited. I would like the equivilent of a 37-40mm if possible, know of anyone that makes folders?

Thanks in advance for the insight.
