i am looking at geting a barfly mount for my bike. and i noticed they have some integrated ones, but i have a cannondale c3 stem and was wondering if anyone knew if they could work for them. as id think if the bolt spread was the same the fizik one could work heres the mounts i have seen there may be lots more. or if anyone knows if fizik makes a -12 degree r1 or r3 stem as i cant seem to find them
