Can the SRAM Rival 1 rear derailleur be used with an 11-46T cassette?
Having fitted a few of these, it works on some bikes better than others. I think this is to do with derailleur bolt drop distance. The derailleur can struggle shifting in and out of the 46.
I have had more success using these derailleurs on 11-46t 10sp cassettes with 10sp shifters where the margin for error is better.
The size of the front ring doesn't matter as long as the chain is the right length.
