I haven't done much with the hybrids yet, but the other guy I work with was working on one and the wheel was bad when it came in, so he trued it and went for a test ride and had to do it again. And then said something about how he hated hybrids, I guess after he put some weight on a turn that it came out of true, I guess that type its common, as far as the term , I will find out when I go back in Wednesday.
