The "Overlap" horse has been pounded to jelly .....

As for number of gears---have any of you been either carrying a load, climbing a hill, or fighting a fierce wind--or any two or three of those at once---and wished for a gear a tiny bit lower than the one you were using after having tired the next step down---not in order but in ratio---and found it too big by the tiniest of margins?

I remember a day coming out of Colorado into Kansas where we had nonstop hills and a 20-25 mph headwind ... I would have loved a CVT or a 3x33 on that day -- quarter-tooth margins?

Anyway ... at some point this approaches the Rydabent Theorem--"if I don't need it it doesn't need to exist." Indyfabz likes that set-up, and that is all the justification he needs, and the rest of us are just audience members talking during the performance.

So a 3x11 is 44 times better than a 2x11?

I kind of agree if hunting across chainrings to find a specific half gear within the overlap is your thing. I've learnt something new here as I never realised people even did that! I use the overlap on double chainrings all the time to save shifting the front more often, but I can't ever remember shifting the front to find a slightly different overlap gear on the other ring. But then it's been a long time since I had less than 11 gears on the cassette and I'm not overly fussy about cadence.

But I was just responding to the claim that there was very little overlap. Not suggesting overlap is a bad thing, just that it exists.

To get to Rydabent's level I would need to state that something I don't use or properly understand is useless and some sort of sales/marketing scam.

Yes.

From Dubois, Wyoming all the way to Canon City, Co, I fought a 30-50 mph headwind. When I am TT at 30 mph. When I am touring heavily loaded and there is a headwind, my full loaded touring bike still has half step gearing in the 40-80 inch range for just that reason.

39x42 chainrings and a 9 speed 12-36 cassette. This works out to 29.7 to 95.8 GI and 18 unduplicated gears using 35mm 700c wheels and tires.

I don't know how many is "too many" but I have determined that two is the minimum required for mountain biking, if, as you say, I want to ride both up and down the hills.

I did not read all 7 pages of this thread, so I am likely repeating someone by pointing out that we do not have more gears now than we did 20 years ago.

More cogs, fewer rings, fewer gear combos.

btw, I am not aware of any tests that indicate that chain life has on the whole decreased with more gears in the back. But they have gotten more expensive.

That’s a three speed.

1- Sit
2- Stand
