I have a question for those "petite" women who ride a rode bike with 650 wheels. I have been given some many different opinions by the lbs people - mostly men, that I am unsure what to believe and what not to believe. My questions are 1)assuming you have ridden a 700 wheeled bike - is the ride on the 650's rougher? and 2) I understand the 650s are easier to get up to speed but is it also more difficult to maintain that speed? I ride with a group of "taller" cyclist who all ride 700 wheels and I don't want to struggle to keep up. I have a chane to by a Trek madone that has 650 wheels but thought I would seek out some expert advice/opinions from you ladies. Thanks for the input.
