Is the standard SRAM Red Etap AXS rear derailleur compatible with a 10-36 cassette?
Can’t find what my rear derailleur is compatible with.
I find info that there is also a long cage which is compatible with 10-36 but I don’t know if I have this kind of cage.
It is as long as the cassette has an XD Drive Body. If you go any bigger (say to a 42 tooth on the top end), the standard RD length is too short - you’ll need a longer cage.
I have an XDR body.
And I have now an 10-26 cassette (12-speed).
And I like to know if I can place a 10-36 cassette (12-speed).
How do I know if I have a 10-36 compatible rear-derailler. Cause there are 2 types of rear-derailleurs.
One with max 10-33, and one newer model which can have 10-36 cassettes.
I had the same issue. Did a 5-day race last year on a 10-33 (same AXS Red but 11-sp). Wanted more range so switched out to a 10-36. Wanted even more range and tried to swap a 10-42 in but it wouldn’t work due to RD length.
I’ve not researched a longer RD to make it happen but figure it exists since I have a dinner plate on my MTB and run 11-sp AXS Red on it as well.
If it came stock with the 10-26 cassette it’s probably not compatible with the 10-36. The only way I know to tell the RED AXS rear derailleurs apart is with a label next to the mounting bolt. Unbolt the rear derailleur and look for this.
