Chrome Moly is on to something with the 11 speed craze. I have my reservations about it as well and quite frankly would never run it as I see no need for it. Honestly what does it do that an 8, 9 or 10 speed set up doesn't do?

I must add my Campy components have easily out lasted by a decade and tens of thousands of miles any of the Suntour and Shimano stuff I have owned.
