So you have a MY1020 / KR5V (original 8/10 shaft) / EC4P motor and want to upgrade to a #35 chain setup to handle the power? Here's the first step: #35 motor sprocket in either 9T or 11T . . . or hell, get BOTH sizes!
Pair it with our Rebel Gears #35 54T or 62T and a #35 chain to complete the upgrade.
