Triple Crank Replacement Help
I have a Shimano rx100 52/42/30 crank. Many of the teeth in the middle ring are worn down and some even gone. I'd like to replace it. Finding that specific crank is a bit challenging. The crank is on an old Cannondale r500 3x7. What size cranks can go on it? Would a 48/38/28 crank work? Thank you.
