Universal RD Hangers?

How about Giants?

I'm not just trying to be contrarian here, but am considering what gravel bike I might get and and really wondering if I need a UDH.. I can't really remember having that many issues with hangers in the past.. even when racing cross.. I certainly wouldn't care if a bike had a UDH, but not sure I care if it doesn't..

on a slightly different topic- anyone have a word on if Specialized is looking to put UDH on a new Diverge anytime soon?

My point was that the non-UDH market is so fragmented that finding a particular non-UDH hanger is actually quite difficult. Often times brands use some common hangers between their models, but historically, Specialized has used a totally different hanger than Giant, who both use a different hanger than Cannondale, etc.

And given that the trend seems to be more towards UDH than otherwise, getting a replacement UDH hanger will only get easier, while getting a non-UDH replacement hanger will get harder.

As for actual bike-buying decisions, I personally wouldn't put the ease of sourcing a replacement derailleur hanger anywhere near the top of the list of features I'm looking for in a new bike. BUT, if you do value that (which the OP to this thread apparently does), that should make a person more likely to want a UDH, not less.

100%. It aggregated me to no end when I’ve snapped a hanger. Especially if the bike was an older model and the manufacturer didn’t have any on-hand.

It’s pretty amazing when used with Transmission. Shifts are crisp. Even mashing uphill, mid-pedal stroke. It’s here to stay.

I keep hearing this, but my bikes with 12sp Shimano XT, 12sp GRX 820, and 11sp Dura-Ace all do the same. I've never ridden Transmission so I won't say it doesn't do it better, but it's so weird that this is such a big talking point when all my Shimano stuff (all of which is mechanical) seems to do the same thing at a fraction of the cost and without any need to keep batteries charged. RD shifts have been smooth every time whether putting down power or not.
