I'm about to begin my first fixed gear conversion, and I'm hoping someone can tell me if what I'm considering is a bad or good idea.

I've got an old steel frame and fork... but the "problem" is that the bike originally had 27" wheels. Yes, I'm aware that I can still buy 27" wheels, BUT the selection is limited and tire selection is even more limited.

Here's my thought... I want to put on 700c wheels, and replace the fork with a 700c fork. With wheels on the bike, the top tube is slightly sloping, about 15mm higher at the head tube than at the seat tube, so the shorter fork will "flatten" it out a bit. AND... this will allow me to run a short reach front brake.

The head tube angle is pretty relaxed, I don't THINK it will affect handling too much.

Any thoughts/comments/suggestions?
