Shimano (manual) road shifters and clutch mechs

Especially for light weight issues concerning cyclocross / touring bikes & parts.

Can someone confirm that there are no clutch rear mechs that will work with Shimano road shifters? I want to go 1x10 this season and have an Absolute Black narrow/wide front chainring. I don't want to use a chain catcher so thought a clutch mech would provide added security but it seems the cable pull for all the Shadow Plus mechs are incompatible.

So what are my options? Switch to SRAM?

There is a thread about di2 in the MTB forum where someone successfully swapped shadow plus cage onto a di2 rear mech.

An XTR Di2 derailleur maybe?

I meant mechanical shifters, not electric.

Looks like I have to switch to SRAM.

Seems like that swap would work for a mechanical DA 9000 rear derailleur seeing as the cages are the same as on Di2.

If you have most of the parts (STIs in particular, they are the most expensive), you could try to get a cheap 9 speed SLX RD (non clutch) and see how far you get with some tuning. Never opened up a MTB RD, but the Shimano road ones have 3 notches for the spring, if you take off the cage. Maybe the MTB ones have something similar, and you can go for the highest tension one. Also get a short cage and maybe lighter pulley wheels (less weight pulling down when hitting a bump, less chance for ghost shifts). Some amount of B screw might help the tension too.

Personally I have never had any problems running a Praxis SS front (old style, not narrow wide) with a 9 speed SLX RD and 10 speed STI. Only used it on gravel roads though, not really any offroad duty.
