currently on some old 105 cranks with 172.5 arms and a 130BCD. looking for a crankset with a straight 24mm spindle (not SRAM) and 170mm with something that will allow for smaller chainrings—110BCD, Shimano asymmetrical, direct mount, etc. I think Rotor, Easton, and Shimano cranks will fit the bill if they have the right spindle.
