Seems like I should really be using it because I’m already running tbatt’s no-slip kit (on the 8lb pulley—like an idiot) and am guessing that’s better designed for the 9lb setup.
And using this 2.85” pulley for scale on the idler below (guessing maybe 2 3/8 sound about right?) that is the idler I need to change out to the gates 36225 which I think is a 3”?
