This summer I plan on doing a little state-wide tour called Ragbrai. With my only bike being a hardtail mountain bike, I will likely pull a BOB and add some aerobars for hand positions. My question...what should I look for in aerobars. My wife won't let me go to France, so I won't be on the Tour any time soon, thus I really only need these areobars for very occasional use. I would assume that you get what you pay for, but since I don't need great longivity, would a cheaper set do the trick?
