Im trying to locate an all black FSA 54T chaingring for my TT bike... the Metron ring just looks out of place , and its designed to be used with the crank to make the logos match..

Anyways, I think I have found a 54/42 combo all black, but they are listed as N10

Is N10 compatible with 11s Di2

I have used N10 50/34t with Force22 without issues for thousands of miles. I also plan to use N10 52/36t with a new Force22 build. In the past, I used Campy 10-speed crank with 11-speed without issues.

I ended up going a different route, but this is the email I got from FSA Europe :

Sorry but no the N10 ring is not upwards compatible with 11spd drive trains. Only the N10/11 or N11 chain rings will work on both 11spd and 10spd drive trains.

Yours works fine.. :noidea:

Yup, mine worked fine, which is why I am building up a new bike with Force22 and FSA SL-K 52/36t N10 rings.

My RED exogram 10-speed worked just fine with RED22 too. Also, I successfully used Chorus 10-speed with SR 11-speed.

Yep, will be good. I ran FSA N10 crank/rings with DA9000 for quite some time and I did not have any front shift issues. My youngest son is now riding the same bike with the same setup. Zero issues, all good. :thumbup:

Once again, I dare anyone to take both 11 and 10 speed rings and measure and show any dimensional difference. I can't find any. I've used both types of many manufacturers interchangeably with no issue. There are no published dimensional differences that I have found.
