Shimano SLX 165mm arm length crankset. M7100. 52mm chainline. 172mm q factor. Bought the wrong size, never ridden, or had pedals fitted. I have just inserted the axle through the bottom bracket. See pictures for more detail on fitment. Includes what is shown in pictures. No spacers or chainring. Original box but I can't figure out how to reformat the internal packaging !!
