Well, I guess I must appear to be new... sigh, ten years later.
I don't think I'm squirrelly, but I can barely drink from a water bottle, my (right turn) cornering sucks, and I am a downhill weenie. I know how to do the quick release, though, but I don't want to have to do it. That, or any other mechanical thing. I *know* what to do, but have never been tested on the road. I have serious mechanical anxiety when I ride, although nothing bad has ever happened. Yes, I have taken more than one class and nothing changes. I am fine in the class, but when I practice at home, I end up with my bike in pieces on the ground and a lot of tears. So, then I stop practicing.
I generally hide this very well when I ride. I ride with one group who actually think I am a "strong" rider or a couple of close friends who know they have to wait for me on the downhills.
But, I can climb.
