Heh, it's fine. My comment was a little tongue in cheek as well.
I'd argue that a lot of bike racers are good mechanics because they can't justify paying someone to do all their work given the costs. Depends on their commitment to racing. There's no way in hell I'd let someone else I didn't know touch my bike before a race. There's only one mechanic who ever looks at my bike, and even after that, I take it home and tweak it.
I need to trust my equipment, and I can only do that if I've done everything and know that it has all been checked and double checked.
