Pros and cons

What is the advantage/disadvantage of using 650c wheels on TT and tri bikes?
Probably a little slower on a TT bike due to higher rolling resistance. They were all the rage at one point, but then fell out of favor. They probably got popular due to their lighter weight, and people got all geeked out about that, but the reality of higher rolling resistance caught up with the fantasy of weight savings, and that was that. Not a huge issue either way, but unless you need the smaller wheels to make the frame fit, they net out a negative.
