Probably a bit of an extension to the mixing groupsets, but a bit more specific.
I'm aware the differences between componentry across the various speeds - 7,8,9 v 10 v 11... but what can be interchanged?
Reason for asking is that while I ordered a 10spd FD (5700), the one that arrived in the post is 11spd (5800)...
I know that you can't mix RDs, chains and cassettes, but what about the FD? Is there any real difference between front derraileurs between speed groups?
Can I successfully use an 11spd FD on a 10spd setup?
