I was looking for a cassette ratio that would help maintain cadence on extended climbs and this Ultegra 11-30 was just enough of an improvement over 11-38 to help. Also, as used with me DA Di2 drive train, it required no modification to rear derailleur cage or chain length in order to work immediately.
