i have a m752 crank with worn out, broken tooth chain rings. i want to replace the rings with larger ones but finding a set is a problem. enter fsa pro rings 104/64 48/36/26t, i can call them and order the set. will they fit?
well fsa has a web store and i did not see any mention about being a dealer. i did not see the pro rings listed on their web store so i sent them an email, stating i has interested to purchase a set, the reply was to give them a call and order them. that's the story.
i have a new alivio crank that has the same bolt pattern and i dissembled it to see if i could use the rings on the xt crank. the holes lined up but the lip the ring drops on did not. the bolt circle is not the sole consideration.
