I don't know about everyone else but if I never have to explain chain twist or cross chaining that will be just fine. I'm sick of telling noobs that a bike does not shift like a car. Especially with the new 30 and 33 speeds people seem to have a hard time getting it through their heads that some gears are redundant and unusable.Even 21 speeds have some gear combos that are ill advised to use like 7th gear or 15th gear. The concept is easy enough to explain and even demonstrate but I think they feel cheated if they can't ride in every gear the bike has. I agree that the derailleur system of shifting has it's limitations but until they come up with something better (IGH) I guess I will have to repeat myself again and again why this is a problem with the design not the bike itself. Shift in groups I say, but the concept is tough for some to process. Anyway I feel better getting off my chest.
