For anyone considering chainrings from XM Carbon — I’ve had two sets arrive: a 52/36T and a 53/39T.
I didn’t buy both — XM accidentally sent the 52/36T in error. But to be fair, they responded quickly and sorted it out. The correct 53/39T set arrived today, and the 52/36T was delivered on Monday.
Side by side comparison to the Cybrei rings will post pics when I fit to my DFS Carbon crank with complete weight
