Well, to refresh your memory, this is what I recommend. I've turned 3 friends onto them, now, too. They're 55 bucks, I've never had them come off, and they don't hit my foot (and I've used them a classic road bike, a mountain bike and my Atlantis). A grocery bag fits in each one, as long as you don't over fill it width-wise. I've had them for about a year and a half, and I use them constantly. I use them almost every time I ride.

I don't use them in KS, because the wind would take me to TX. They will slow you down in the wind like parachutes, but they snap closed right on the bike when you're not using them. They also have a thing that connects them to each other if you need.

So easy to get off and on that you don't even think about avoiding it.
