Its clever, clean design also guarantees stable, efficient and effortless gear changes, and can handle a cassette range of 11 to 34 teeth.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFurthermore, this derailleur benefits from \u003cstrong\u003eSynchronized Shift\u003c\/strong\u003e technology, which improves shifting efficiency while you ride.
