I'm going to wait on 1X until they get to 17 and I can have my usual gaps. Only 4 more cogs to go.
Isn't there a law, like the computer memory doubling very so many years that applies to cogs?
Just for fun, does anyone have the dates of the start of the next cog? I just make a graph of year-cog number from 1900 to present. When as the 1st 2-speed derailleur, 3-speed FW? Etc. I'll toss them in the graph and see if I can derive the law.

There’s math.
No one said there’d be math.
13 is unsafe for so many reasons.
You have to look down twice as long to guess your gear.
The fingers go to ten, the extra one is a risk now with 11.
I’m already skipping cogs.
The whole 13 thing...
Just another waypoint en route to all 1x all the time.
I love mine but a Cat 4 climb last Saturday, 21% at 98 miles in: a double bailed me out or I’d have fallen over.
While a compact crank with 11-32 is getting me by across the board, a 52/36 with 12-36, a Roadlink and a clutched RD. may be my huckleberry.
That’s just the gearing thing. I still can’t wrap my head around brake fluid on a bike.

I still have my doubts over contemporary cycling. I'm still getting used to the idea of having a carbon fork. Time will tell.

A Poisson count model works ok, though the relationship is nearly linear. I get:
G = number of gears
Y = year
G = exp(-22.6028+0.0124Y)
Sorry fellas, but science don't expect a 14-cog cassette before 2033.

I still have the frame. In fact, it was my ride at the first Eroica CA and the last they held in Paso Robles.

Not so fast there. Back in 1973 or 1974, a friend and I made a barn find - literally - of what I eventually found out was a c.1961 Bianchi Competizione. As found, it had a triple crankset with a five-speed freewheel mounted on a 3sp IGH. 5x3x3=45 distinct gears. Beats 3x13=39. They may both be equally ridiculous, though.

As an aside, I really don't understand (nor want to understand) half-step plus granny gearing like on the Miyata 610 I just refurb'd. Half-step seems so bizarre to me. "No sir. I don't like it."

My 1x11 jumps an avg of 3/cog. You and I have discussed that.
Having Campy, Shimano, and SRAM is a bit of a shifting transition issue when riding different bikes. It’s only seconds of time to worry about, but it’s there.
Add in the 3-cog jump with my 1x SRAM, the need to use the FD with my Shimano, and the limited range of my Campagnolo? There are moments of doubt and panic while I flail around the cogs and rings, trying to remember what gear I’m in, what system I’m using, and what’s available. All that on top of “who am I; what am I doing here?”
Comic relief for fellow riders, perhaps. I tend to consider simply riding a 2012 Sportster often during these moments, but the tools and riding gear cost a lot more.

Get a hold of @nlerner. He needs some math help. But in case you're not 100% sure about past participles, he's your guy.

Arguing for future classic & vintage status in 2045. Besides, it's raining today, so I'll be damned if I'm taking one of my vintage bikes out.

I've got Shimano GRX 800 on my Stigmata.
I run a compact double.
I switched back to Shimano/SRAM on most of my "new" bikes.
I haven't been a fan of Campy off road/gravel for years.
However, I love the look of Ekar and this might convince me to give Campy another chance.
This looks like a complete "package" from Campy and I would love to give it a shot.
Keep in mind, I ride almost 90% off road at this point.

Not cheap but I would consider this if I got a new bike.
-i prefer Ergo above all other options. I have barend shifters on my current gravel bike but this is awesome.
-i ride 40 x 11-42. Sometimes a not low enough and sometimes not high enough. Sometimes big jumps with 10 speed. So to run 36 x 9-42 between 13 would be amazing. This would mean a non Campy crank.
- gravel bikes are heavy, this is a little lighter than any other gravel/hydro groups.
At $1800 for the group, and the frame I want is $2200, plus wheels and cockpit, I don't know if I'll ever get it. I like it though

As cog size decreases, the rate of wear increases. If you spend a lot of time on a small cog, it wears out very fast. Also, below 12T or so, the power transfer becomes wavy as the chain engages the teeth one by one. The trend is for smaller and smaller cogs and chainrings. I wish it went the other way, even though that would increase cost and weight.

Some people have a rainy day bike in their quiver. I have a sunny day bike, the rest are all weather. Here's Bob Freeman not afraid to take a show quality Jack Taylor Tour of Britain bike on a 3 day winter tour. He has over 100 vintage bikes in his collection, all in impeccable order. Outside of the ones with wood rims, he'll ride most of them anytime, rain or shine.
Besides, this thread needed more purdy pics of purdy bikes.

I want to update pinky with a new pinky. I don't care for a pink/black color combination, I find it garish. So I was hoping this groupset would be silver, so I could try something new. I'm fine with 1x11 Potenza or Athena.

Here in the PNW, that would limit our vintage bike riding to 3 months. Fenders are where it's at.
