Thanks fkaCarel for your input. Didn't take as criticism. Just opening to everyone the reason of my choice, that's what this forum is all about. Half of the pulleys (Number of teeth >= 136) would have to be made to order whatever the standard. SDP/SI offers a GT2 5M aluminum pulley (28 grooves, 9mm width) for $13,70 USD (I just would like to dodge set screws and Fairloc collars). |
