    I don't typically notice anymore either. Heck, I run 1x on my road bike.

    Road Bike:
    2x setup, 36t/52t, 11-28. Gear inches = 34-124
    1x setup, 50t, 11-40. Gear inches = 33-120
    (I'm too slow to need to pedal faster than 36mph, so 50:11 works fine for me.)

    Commute/Gravel bike:
    Hypothetical 2x setup, 34/50t, 11-32. Gear inches = 28-120
    Actual 1x setup, 46t, 10-42. Gear inches = 29-121

    I don't need 1:1 on the gravel bike. But I will likely drop to a 44t ring, since I also don't need more than a 50:11 on that bike! (Especially with the big tires - that's pedaling at 37mph w/ 38mm tires)

    There are a few cases where I notice the gaps. For example, at Devils Backbone Monster Cross there is a several-mile climb on the Blue Ridge Parkway. It's not super steep but it is a steady grade and it is in those circumstances that I sometimes look for a middle gear.

    Note enough to wish for multiple rings up front, but enough to appreciate there's some value in more gears / tighter clusters. (I don't think Campy is pushing 12sp for 1x, though.)

    The only annoying part about these “upgrades” is if you get the new groupset with more gears, you probably have to get new wheels too. If you’ve got a nice set of 11spd wheels, but then for whatever reason need to replace your groupset, you either have to buy an old groupset to match your old wheels, or buy new wheels to match your new groupset.

    What I hear is an excuse to build more wheels!

    At least for SRAM (XD) the 10-, 11-, and 12-speed cassettes all fit on the same driver. There's also XDR for the yet-to-exist "SRAM 12-speed road cassettes" (you can maybe order a 3T 12sp road cassette now?), which is wider, though may still fit on some hubs, since it is designed to be the same width as the 11sp [non-XD] SRAM/Shimano freehub body.

    I was a little surprised that the SRAM 900 boost rear hub I just bought has an XDR freehub body (with the 1.8mm spacer, so I can run a regular XD cassette). Maybe someone expects road bikes to need BOOST spacing ?? -- Or, maybe more likely, SRAM envisions using that extra 1.8mm to fit a 13th cog? I would like to see an Eagle cassette that maxes out around 40/42t. 50t is ridiculous for any non-MTB application.

    I'm guessing that 13 is where it ends, since thats where you literally can't add another step on a typical 11-23 roadie cassette. Although I guess they could just start adding larger gears to the back. We can look forward to an 11-32 being the smallest cassette you can buy in 20 years, I suppose.

    The article states that for this Campy upgrade at least, the 12 speed works with 11-speed wheels.

    Simple fix. Move the cassette to the middle of the hub. Lots of room there.....

    If you put all the spokes on a single flange, I think it would have to be at the center of the hub, so that would leave you with something less than half the hub width for cogs allowing you to get maybe 18 or 20 on there. Such a wheel might have less than optimal lateral stiffness, however.
