Sora RD compatibility

Postby Red Rider » Thu Jul 12, 2018 2:40 pm

Is this RD able to take an 11-30t cassette (9sp)? It looks to be a medium cage...
Also, are the Sora HG50 and HG400 cassettes interchangeable?

No and yes.....

That 3400-series model is limited to 28T by its upper body geometry. The longer cage allows it the chain length to run with a triple-ring crank.

All 9-sp. cassettes, within relevant derailleur limitations are interchangeable.
I had a thought, but it got run over as it crossed my mind.
