Quality components. I'd have to tell you that again from my experience, going up one level of component doesn't get you a huge improvement in anything. It might be a bit lighter, but on a hybrid you aren't looking for an ultralight, and a few grams won't mean much (except on the wheels). The more you pay, the lighter you get, it may shift a fraction faster but again, tough to notice. I don't think anyone ever won a race because they ran DURA ACE versus Ultegra.
