"I've been hearing people say more gears are for fools ever since Dura-Ace went from 6 to 7 speeds. They were wrong then and you are wrong now. More gears mean more ranges to choose from and less jumps between ranges. So it's hardly imperative but it's not for fools either. That's just an ignorant thing to say."
It isn't ignorant, it is my opinion which the last I checked was still ok for me to have and one that other cyclists also have. I have test ridden 11 speed and didn't notice gaining anything. Maybe jumping from 6 to 9 speed would be a difference rather than going from 10 to 11 speed. But how many of us even use all 20 or 22 gears on our bikes? I use ~6-8 gears of the 10 I have on my current bike. Going from 10 speed to 11 speed, that is just marketing and road bikers out of any group is more than willing to throw away perfectly good 10 speed groupsets and pay for that extra gear. Along with the tighter tolerances and thinner chains. Plus the issue of 11 speed complicating wheel dishing and potentially getting a structurally weaker rear wheel.
You would see a bigger jump in performance and enjoyment going with electronic groupset than jumping from 10 speed to 11 speed. Has been my opinion and will continue to be so. It is a 'forced' upgrade. Enhancing 10 speed wasn't going to make Shimano/SRAM/Campy any more money. Campy's move to 11 speed was unique and got them sales. S&S followed along.
I can see 11 speed use for MTB where you could run a 1x11 and get great use from that. But for road, really? We need to start petitioning S/S/C for 12 speeds. They are holding out on us. At least Tiso is giving us 12 gears. Good for them.
