it would be interesting to see if the new composite gears for the BMC are the same size. maybe there is some way to convince bafang to manufacture with the composite gears from the start.

If nylon can make it as far as it has been described here, then non anodized 6011-t6 can handle it with no problem. It would wear over time because it is softer than steel, but still last a while.

It will last for ever then.Running the motor under load with the gear naked on the post could chew up the post then even if you want to fit a bearing later it will be a bad fit on the chewed out post.
