I agree- but can't help to think that is argument sounds so short sighted. What if they said the same thing at three speed cassettes? Innovation is good, and it will be done in small incremental steps. You don't have to keep up personally (wait for several generations when there is a substantial change to what you have), but as an industry goes, I am glad they are adding a cog.superflychief said:No! you can only make old tech lighter and fancier till you have to introduce something new to the market to make more money. Does 1 extra ring with 1-2 extra teeth in your range make much of a difference? NO! it's so marginal that it's really not necessary. I am on 9 speed as well and definitely have no plans of moving to 10 for that same reason.
