When will the push to add gears to bikes end. My Rans has 27 gears, and even that is probably too many. Now there are 10 and I think I have heard of someone having 11 speeds in the rear. This is over kill and makes no sense. Ever more gears call for thinner chains that are weaker and wear out faster. Also more cogs in the rear call for more dish making the rear wheel weaker.
