Howard in reply to @Brommers
I'm not aware of a Shimano 9sp rear mech with a clutch

There isn't one.
- I think that came in with 10 speed - but my knowledge of Shimano derailleurs is far from exhaustive so I may be wrong.
They released ten speed as shadow - a lower profile, and shadow +, low profile with the clutch. As you say, neither are compatible with road shifters - they use the 'Dyna-Sys' pull ratio, whatever that means.

The only advantage I can think of for using a 9sp MTB mech is that they have a longer cage so you can run a bigger cassette.

As you know, only if you need the extra cage to pick up the chain slack. At Howard towers we ran 1x10 with 11-32 on short cage mechs - cage length does not dictate maximum tooth capacity. I think I run an 11-36 on a short cage Zee mech on the jokes long travel bike.

I'm really surprised by how shite the options are for running 1x10 shimano beyond MTBs.

Seems likely, I have a short cage X7 on my SRAM 1×10 (12-36). It's only 24T total capacity, well within the capability of a short cage. Shimano road RDs can usually be pushed to about 30T maximum sprocket, so you only actually need to contemplate MTB RDs if you're going bigger than that.

so you only actually need to contemplate MTB RDs if you're going bigger than that.
OR if you want clutch and high tension.
