A neighbor gave me a 11/36 cassette and a “SRAM XO” long cage RD. I’m thinking to put on my CX as I usually ride that like touring.

Current on my CX I have a compact rival 50/34. So what chainring would I need up front so I can use this cassette and RD?

I tried it and in 50T was way too short even though already lengthen the chain.


Edit: neighbor wanted to keep the deore and instead gave me a SRAM XO 10sp RD. I don’t mind since it’s free..

Depends which model, latest one has a capacity of 43t so with 11/36 and 34/50 you are well within spec on every count. ... 0-SGS.html

Not directly related to your question but just note that shimano road shifters dont play too well with shimano mtb rear derailleurs

Correction... now it’s a SRAM XO... he’s keeping the deore.

So how come can’t shift up when in 50t in front? I left a lot of links but looks like the legs will be overly stretched?
