Thank goodness for this thread! It (+ a little research and a lot of measuring) just answered a question I had. I'll be doing something similar to the OP, at least temporarily.I'll be using a Surly Instigator fork, which has a crown higher than most 700C forks, so I might not even have my frame lower than it was originally supposed to - or at least, it will be just a little bit lower, a few mm at most.

Excellent thread!
