Anyone know if in theory or with personal experience 9+10s Ceramic Speed jockey wheel (11-tooth) will run on a shim da 11s drivetrain? Thanks

Should be OK as the 10 speed and 11 speed have the same internal measurement inside the chain. That assumes you can make it fit nicely in your mech cage, of course :)
Updated: Racing again! Thought this was unlikely! Eventually, I may even have a decent race!
Edit: 2015: darn near won the best South Island series (got second in age

I'm running an unmodified 10s Red rear derailleur in an 11s system, no issues with the pullies.

I've been using 10 sp Shimano pulleys from F1 Ceramic. When I switched to 11 sp they sent me new dustcovers as the spacing of the cage is narrower on 11sp. Something like 7mm vs 8mm. Without the change, the pulleys worked but the chain dropped on occasion due to the spacing. The new narrower dustcaps solved this. Not sure if ceramci speed is the same, but f1 ceramic worked this way. Hope this helps!
