so to Steve's (CC) approval, i've committed to installing the RF Turbine IB. i've put in the RF taperlock 122mm axle BB, as well i swapped over what i believe to be very early RF chainrings from the Cirrus that don't have 8/9 speed markings. the rings have a different cut than any of the other rings i've had. the cut aways are larger areas and the a pattern line is more curved, instead of the typical harder straight edges. also the ramping is different. the rings have a much nicer flow away from the clover spyder that matches quite nicely.
as i ran out of full sets of Syncros COM, i went with a Shimano "one-key-release" with a set of Ti bolts from a COM. this in combination with a set of Shimano chainring bolts i happen to have.
