Still waiting for my LBS to get some M520's in stock, so naturally, I find things to worry about.

Here's what worries me. . .

Falling -- not when practicing, not on the grass in the park, none of that. I don't care about that too much. It's part of the learning curve and I can accept that.

But I ride city streets almost exclusively. I worry about falling in a month or two or three when pulling up to a light, long after I've gottn used to clipless, but for some reason, when I'm distracted and fail to clip out. Falling in traffic, I guess to be more specific. I can live with a bruised ego, an embarrassing moment, no problemo.

But I'm worried I'll fall to the left, INTO traffic approaching a light, and the car won't have time to stop, and my head will be crushed like a ripe melon, leaving my DNA all over the street.

That's what I worry about.
