Cross top levers do rather fall into the 'crude but effective' category, but there are good reasons for having them. I wasn't deriding the cross tops, just pointing out that you don't get the full benefit of drop bars if you don't have normal drop bar levers, either instead of or in addition to, cross tops. It is the case that the cross tops are 'supplementary' levers, having arrived on drop bars after the normal levers and, by design, in addition to them.
