asked by: a guest Is this compatible with 105 fc5800 crankarm? I have a powermeter on there and would love to keep it on.
anwered by: canteau The Shimano FC-5800 crankarm should physically fit onto the spindle of the RS500 crankset because all of the Shimano HollowTech II cranks use the same interface. There might be some differences in the shape of the 2 arms, but without having both of them in front of me, it would be difficult to confirm.
