Rear Derailleur Recommendation

[temporider]

Great phots! And I think your choice to install a dogfang mitigates the 'long' chain dropping risk. Please would you indulge me(us) by sharing images from the side of the chain on 1) large/large and 2) small/small.

Small/small and big/big.

Looks like you've JUST got away with the chain wrap issue 👍

About these dog-fangs ... I've always guessed there has to be a drawback (TANSTAFL!). Otherwise why not just put the derailleur mount hole lower? Or make frames with 2 holes?? The above photo possibly illustrates one:
It's clear that your upper jockey ends up miiiiiiles from the smaller sprockets. Does this impact shifting much?

Think you have to add one more link (1") into that chain. And put up with the noisiness if you stray into small chainring & smallest few sprockets - take as an immediate indicator to shift into the middle ring.
Is @matticus mixing up his lupus and canis dentistry?

What problems arise when the QR lever is on the drive side?

The gear cable outer gets in the way of operating/turning the QR lever before 'closing': having it on the left side avoids this inconvenience (and it's normal).

No problems with shifting - I still use the down tube friction shifters. The dog fang is doing a good job of keeping the chain on the small ring. It would drop off intermittently in the past but I’m getting positive engagement now.

Back in the earliest days of the QR, the lever was on the RHS. It took a decade or so to swap the lever to the LHS.

Yes!!! I have no idea what the hanger-extender thingies are called, so just grabbed some random jargon in a random post. Might edit my post ...

The Dog Fang is the the thing on the front to stop the chain coming off inwards Matticus.

I refer the honourable member to Post #10 above which (excellently) has pictures to illustrate what's what.

Yes yes ... this Horrible Member gets it now, thankyou. (and Post #10 was indeed excellent).

I even have home-made Dog Fangs on some of my bikes! 🤦‍♀️ (zip-ties cut to shape, as you asked. There's nowt much you can't fix with the right zip-tie ... )

I prefer the Foxmolar. A far superior product.

But surely not as good as a Dogtrouser?
