Just checking before I buy these rings... compatible with 10-speed chains, correct? Close-up photos of the product online show "11-Speed" stamped on the rings. But I've always read that road double chainrings are always cross-compatible for 10-sp and 11-sp. No such thing as an 11-speed specific road double... correct?
Thanks. Had a shop install the new rings/cranks yesterday, seems to work fine. Takes a bit longer for the chain to move into the big ring, perhaps just need to adjust front der.
Easton rep said via email that the rings are designed for 11-sp chains, stopped short of saying that 10-speed would work fine.
There may be a slight difference in chainline between your old and new setups. It doesn't take much to affect the front shifting.
With a 10 speed chain, it's possible that you'll get more chain rub on the inside of the big ring when you're in the small/small combination, but you shouldn't be using that anyway.
By reasoning, the 10 speed chain should indeed not really give an issue. It's only the outer width that is different and, unlike on a cassette, the outside width should not affect how it shifts/roles on the chain rings (especially since your front mech was already using the 10 speed chain).
If in practice you do have an issue (like bnystrom mentioned where the width causes rubbing) then you can always consider running a 11 speed chain and see if that runs better!
