I think the best deal in bibs are the Voler bibs from Hammer Nutrition at around $45 (
www.hammernutrition.com ). I've got a pair of Aerotechs, a pair of Zoot Sports, and just returned a pair of Canaris to Sierra Trading Post because I wore a hole in them in less than 200 miles. The Zoots and the Aerotechs are both pretty good, but the Volers just feel a bit nicer to me. I'm also a big fan of Hammer's vitamins.
