This is a thread posted by a person who says gearing "is all a foreign language to me".

The odds that such a person is going to buy a gearing system that costs maybe $1,500 more than the most expensive derailleur set-up (and weighs a couple pounds more than that derailleur set-up), and then is also going to buy a new super-expensive bike with the special frame that this extremely esoteric gearing system requires (almost no examples of which are sold in the US), and then, in order to maintain this system, is also going to learn advanced bike mechanic skills or else move to one of the maybe two or three US cities where there is a mechanic that has ever worked on Pinion gears, are so close to zero that your posting twice in this thread about the virtues of Pinion gearing is a complete waste of everyone's time.
