Okay, buying a compact double crank 50-34. What rear cassette would give best climbing gear options...........a 12-23, 12-25, 12-27, 11-21, you get the picture.
It will be for a 10 spd. setup.
11-21 with 54/42 rings!
My wife is getting a 50/34 compact and we went with a 12-27 cassette. The gearing loss over her 30x25 triple is negligible, though you might not need anything as steep as a 34x27.
