Something that would make a huge difference would be if we could buy a lever that worked with drops for what a moderate priced MTB lever cost. For touring a lot of guys are using bar ends, or Rohloff, and don't need a hydro brifter, or some kind of electronic integrated system. A Hydro drops levers would be a huge game changer. But working throught what the market is going to consider the winner in 10 years for road and XC is a huge task for the makers.

There are patches that allow a regular lever to activate a hydro system, but that is just so awful. The hylex system is pretty nicely priced, at 160 a wheel, by the time you get BB7 and some levers and good cables it is in the ballpark.
