Well, compared to a lot of the people here on TE, I know nothing. I am a mechanical dunce, from the actual "doing the job" perspective, but the difference is I *know* what questions to ask and I can talk about components, etc. with a reasonable amount of intelligence. And even that has made a world of difference. Even though DH does all of our mechanics, I feel I can walk into any shop and they are not going to give me the "stupid woman" treatment, which has occurred in the past.
Most of the people at today's event had hybrids or entry level road bikes. I was glad we had my Jamis Coda there, to show that I ride different bikes for different purposes. I could compare and contrast it with my road bike and the mountain bike we had on display.
