95% comes down to the rider
the remaining 5% will get you 10w efficiency boost at best (which maybe over a 200km course, might make a difference, not on your average ride or commute though)
chaincases seem like a good idea though, city bikes with internal gear hubs generally have them
not sure how it would look with a derailleur and cassette
>>1803361looks interesting, a lot of riders do like disc brake levers because they are longer (horizontally), giving you this sort of effect and ability to rest your forearms
also fuck UCI
also forgot to mention that most of the 'innovation' comes from triathlon tt bikes these days
