The smallest standard rings for a 110BCD crankset is 34T. That is it. To get a lower crankset granny gear requires different crankarms.


Note 1) PraxisWorks has a 48/32 crankset based on 110BCD...that they make work by doing some fancy engineering of bolt placement inside the the ring.

Note 2) There are several 46/30 (or lower) cranksets to pick from-however almost all are square taper BB. And will cost $250USD-$400USD new retail. In no particular order...IRD Defiant 46/30 ($250), White Industries VBC cranks and rings ($200 for crank arms plus $200 for rings), Sugino OX901D 46/30 ($399).
