eddieb makes sense....however if you decide to stick with 27inch wheels, go with the sun rims if you plan on using the wheels for awhile. I have a pair of 27" CR18s built with surly hubs. Its a tough wheelset that has brought me nothing but satisfaction. Since then, I've built up other bikes with 700c wheels, but I keep an old conversion around with my 27" wheels for riding in the rain and what not.
