10 speed vs 11 speed chain rings

[Bianchi Boy]

I an considering a new chain set for my 11 speed bike and have always got on with TA rings. There is an 11 speed specific called Syrius and the 8, 9 and 10 speed zepher. There is a tiny difference in the chain dimensions for 10 and 11 speed. So could I use Zepher rings with 11 speed. Struggling to thing that the tiny width difference will make a difference.

So will Zepher TA rings work with 11 speed?

at some point there will be a problem for sure.  11s chains are a little bit narrower than 10s ones.

 One failure mode is that the chain skates on top of the small chainring rather than sits on it; whether you get that will depend on lots of things including whether the chainset has spider arms that are slightly thicker than the norm (for 10s/11s ones) or not.

it'll probably work OK, but there is only one way to find out...

11s chains are a little bit narrower than 10s ones.

Externally, yes.

But internally 10 and 11 (and 9) speed are the same width.
