Crankar sprocket.

NOTE: The original crankarm assembly is NLA and we will not be getting anymore in once our existing stock is gone. You can use the crank arm (4003822) and sprocket (102000015) as a replacement.

Please note that 102000015 does not have a place for the magnet. You will either have to mount the magnet to the new sprocket or disregard the magnet entirely, which means your speed sensor will not work..
