This product is an awfully complicated and heavy solution to a problem that drop bars already solve quite nicely. A drop bar set at seat height or higher offers more positions for less weight. Another poster said some people are "intimidated" by drop bars. Huh? Drop bars are scary?

The first time this mechanism fails(and law of averages says it will fail on someone) and a rider ends up doing a faceplant it's going to cost you a lot of money. Having people monkeying around with their bar height while moving is a recipe for disaster.
