If change is necessary the new reality probably won't totally suck if we lose the 11 cog and a few thousand pages could easily be written about it like, just last month I spun out doing 32.1 mph spinning a 50x11 at 90 RPM... what am I 'gonna do now, drop down to 29.4 MPH with my puny 12t cog? Increase my cadence to 100? Oh wait... if I increase my cadence to 99 I can still do 30 mph in 13t so, never mind.
