Thanks for the offer saddlesores, but I'm also after the 700C's. My touring bike has 48 spoke maxicar hubs with alesa rims. I rode them on an around the world trip, and later again in South America. Carried lots of weigth (water!), never broke a spoke, only needed them trued once halfway on my 25,000 mile rtw trip. So I'm sold on 48 spokes. I just bought new Phil Wood hubs, now am trying to find some nice rims. Heard good stuf about Mavic, not sure about the Sun's.
Thanks again,
