Yeah, I kinda covered that in my previous posts. It's not for me either, however there was a time when folks thought it was ludicrous to purchase plain bottled water, ride a bike using tubes inside tires, or cables inside a frame, place additional (areo) tubes on drop handlebars, wear beer cooler material on their head, wax their legs as well as their chains, upgrade to n+1 gear, etc.

My touring bike has had a Rohloff hub on it for almost 20 years. I run it with a 38t chainring and 17t cog, which gives me a top gear of 90" and a low of 17" - I can't see why you'd want to complicate things with multiple rear cogs plus derailleur. I've been up lots of substantial climbs in the Alps and Pyrenees on that bike, and not felt that I wanted a lower gear. The hardest climb I can recall on it was Mt Rigi in Switzerland, which averaged 11% for about a dozen kilometres, with sections over 25% and the final three kilometres averaging just over 14%. My gearing was adequate but I had problems with the front wheel coming off the ground on the steepest sections.

True words indeed

It's all good. I don't mind being a heretic. Not everything has to make sense (see original thread title), nor do I personally disagree with needing more than 14 unique speeds/gears. Just wait, in ten years I will write here I told you so, while I wax on about my single speed bike.

When did multiple gear first appear?

The first generation of bikes are single speed...

It happened pretty early on, in the 1920's, IIRC. Bikes were made with dual-sided hubs with different cogs on each side. To change gears, you had to get off the bike, remove the rear wheel, flip it around and reinstall it. Needless to say, riders didn't change gears very often.

A framebuilding friend in Perth who built our touring tandem for us used to tour with his brother on this sort of setup - double-sided fixed wheel with track dropouts on the frames, and two chainrings about three tooth different up front. In the 1980s they rode the Gunbarrel Hwy thus equipped. I accompanied them from Perth for the first couple of days of the trip. They would get up in the morning, look at the sky and the wind direction, and decide what gear they were going to put the bike in for that day.

A bit of blurb on the Gunbarrel Hwy here - it's about 1000 miles of rutted corrugated desert track, with not a single town along its length: https://en.wikipedia.org/wiki/Gunbarrel_Highway

Edit: I just found this short bit of YT video of tackling the corrugations on the road by bicycle - https://www.youtube.com/watch?v=OtHj7a4MFNk

That looks like absolutely miserable riding! It seems like a perfect place for a full-suspension fat bike, with a suspension stem and seatpost. ;-)

Is there a continuous non washboard along the edges, or does that soften up and present those challenges.

I'm sure Backroad or some other posh tour companies run tours out there...

C'mon Sparky, just think of it as a 1000 mile "bike massage"! ;-)

Nick's Bicycle Retailer helmet article led to this:

SRAM NX Eagle brings 1x12 to lower price point

CHICAGO (BRAIN) SRAM's new NX Eagle offers a 1x12 speed offroad drivetrain for about $375 for the group. The group shares many features with SRAM's XX1, X01 and GX drivetrains. Notably, its 11-50 tooth cassette works with Shimano-type cassette bodies. SRAM is targeting the group at entry level mountain bike and e-MTB use.
