Can I fit a compact cassette with a long cage derailleur? my bike currently has a combination of 50X34 crankset and an 11x32 cassette and it looks like my rear derailleur is a long cage. I'm buying new wheels and I want to take the opportunity to try and buy a more compact cassette, maybe an 11x30 or 11x28. My question is, will I have problems with my current derailleur? Do I need to make some modifications?
Thanks in advance
Unlikely to cause any problems. A long cage R7000 (Shadow type) is rated for 28-34t cassettes. The short cage is rated for 25-30t, so going from 32t to 30t or 28t would be fine.
Expect to need to make normal adjustments for the new cassette, but it should work fine.
Of course it depends which precise RD you have, and since you didn't say I can't be 100% certain.
