sram derailleur question for 2020 s40

[Howard Goldstein]

Hi. I mangled my derailleur last week on my 2020 s40 with (i believe) stock parts. Two bike shops told me that this is not an easy part to come by these days. I am wondering if anyone knows the specific part to search for (is it just sram apex? is there cage sizes consideration or something?). is there some other part that is interchangeable?

Thanks..

Looks like a SRAM Apex 1 Long cage derailleur for 11 speed system, max 42T cassette compatible with Sram shifters. Google search seems to show they are available at various places.

On the SRAM page you should be able to find the max cassette size for your Apex. My SRAM FORCE AXS RD allows up to a 33t big gear and I am running a Shimano Ultegra 11-30 on it now, but I believe the Ultegra 11-34 would fit on it as well. 1 thing you should do other than that is to make sure your derailleur hangar wasn't bent. If it was then you will have very frustrating issues with shifting.
