Here's a typical scenario: "Cool, [insert big company name here] released a new off-road bike! Looks pretty good, nice geometry. Wait. What the heck spacing is that? Proprietary? New standard? There are no existing wheels that will work with that bike except for [big company]'s. Guess I'm not buying that or suggesting it to anyone."
Don't get me started on bottom brackets. Did you know the solution for creaky, poorly fitting, press-fit bottom brackets is a threaded system? Guess we're ahead of the curve on that one!
While not applicable for touring or rando bikes, electronic shifting is super nifty. You really need to try it to appreciate how ridiculously fast and easy it is to switch gears. Also, you can mix and match road and mountain drivetrains to fine tune a rider's needs.
I'm a big believer in 1x systems. They're dead simple, lightweight, with very reasonable gear ranges. They're perfect for a large audience from 'crossers, commuters, MTB'ers, and even credit card tourers.
