The part of the axle which comes out of your motor need to be only 12mm. If your is not longer all is good. If no than you need to cut it. I speak about the motor axle all time…
You do need to cut the motor shaft 12mm off in order to fit the motor drug, sorry motor gear
Not in California…no one ive know has ever used the words gears to mean drugs… and unfortunately i know a lot of people that use drugs.
In gym culture, “gear” is slang for steroids
