The chainring on my Shimano Alfine 39T crankset (FC-S501) is severely worn and needs to be replaced.
Can I replace it with any chain ring that has the same BCD, bolt count and teeth?
I am looking in particular at replacing it with a chainwheel from the 105 range (Y1M339000). Will it fit?
I am concerned mostly about the shape of the tabs not meshing properly with the spider, or does it not matter? Do all Shimano chainrings have the same cutout?
