Gotcha...thank you.

So, in principle:
- the material used should be sturdy enough to take the repeated forces of pressing against/riding the BBs
- the material should be "sticky" enough to be able to grip the BB
- the material or combinations of the layers of the roller should be such that it does not rotate on the bar

Is the "roller" (that shouldn't roll) chemically fixed to the bar (i.e. glued)? Or is it solely a friction/mechanical fit (super tight fit)?

Edit...likewise re. the cushions that are used between the cage and the barrel...the stiffer the material the more force it'll apply and the softer/squidgyer the material the "easier" the force it'll apply to the BB, right?

Thanks again,

Tys
