Why are chain drops so common on the road, but not in pro XC or MTB events?
Because almost all MTB racers use an upper chain guide. Look at world cup bikes and you'll see a small plastic guide at the top of the chainring. My enduro and DH bikes have both upper and lower guides because I'll sometimes end a section of bumpy coasting with a 1/4 back pedal. I have 1 bike that I don't race without a guide (still with narrow/wide ring and clutch) that drops the chain sometimes.

PG is definitely an egotistical guy. I've never ridden with him, (Ted King I have) but I've been around him a few times at the TOC before he retired, and lets just say he believes being a Pro Cyclist is one of the highest callings a person can have. Not to say he isn't nice and friendly cause he is. Just a bit too much into self-promotion.

Why don’t they use anti chain drop stuff ? Simple solution to a simple problem...

Like what?... clutches and upper chain guides and lower chain guides, etc etc.? That’s more faff than a nice, simple perfectly functioning front derailleur that would allow the use of two chain rings and proper road gearing. The whole 1x thing for road racing is on its deathbed before it even got up for breakfast.

^+1, The marketing talk about road 1x always goes on about it being simple and 'clean' and light weight, which it is if you keep the same cassette as normal and just lose the chainring and FD. But just doing that has several flaws, which are fixed using heavy wide range cassettes, overly bulky (looking at you SRAM) narrow-wide rings, and chain guides that don't weigh much less than a high end FD. Also, nobody has won the Tour de France on a bike with only one chainring since around about the time of WWII...
Rant over :D.

I don't know that the 3T frame has a way to mount one. There isn't a FD hanger to use and the tube shape doesn't look like it would make it at all easy to clamp something on that would hold an anti chain drop device.

Indeed. The 3T Strada frame is designed without any way to mount a FD.

Even if it did... why? If it did I’m sure they’d all have front derailleurs and double chainrings back on.

Ok I'll bite :) 1x obviously has kinks to be worked out for road racing. Having said that, I think there is a lot to be said for going in that direction. Even at the pro level...how many pros are spending time in a 36/39 front ring and 11-15ish in the rear? My guess is not much. As the 1x system evolves, and we get to 14 speeds, it's not inconceivable.

Improve:
1. Chain drop w/ better narrow-wide chainring and better clutch RD
2. 14-15 speed RD
3. Lighter cassette (even at 14/15 speeds, look at an old 7 spd cassette)
4. Possible breakthrough in RD design to allow for smoother shifting across to a "climbing block"

Personally I think the 1x haters are thinking a bit inside the box rather than seeing how the racing bicycle could evolve without the need for a FD. And in the mean time, I agree it sucks for AquaBlue because the tech isn't quite there yet.

I dislike 1x because of the stupid big cogs at the back. You can't help that with any of that 4 points.
I'd much prefer if they invented a gear system which gets rid of the array of cogs instead.

Another slight disadvantage to one-by, (and I do have it on my mtb and I like it a lot), is that narrow-wide chainrings wear out SUPER fast.......the cross guys on this board that use it should be able to confirm.

Most MTB riders get plenty of mileage out of them. Which sees nastier conditions than someone will ever face on the road. Got 6+ months on the current ring, at 12-15hrs a week.

Yes, they look absolutely ridiculous. UCI needs to step up and ensure pro bikes look pro. Rear mech limited to 28 max and nothing less than 53 big ring. I don’t want to see old man ratios in the pro peloton!
