Is there any difference between diff pulleys made of delrin and graphite?
I believe weight and lasting are approx the same. But what about friction? Is it more about finish, than material?
Reason for asking, is that I already got graphite versions on my Pro2, but I've found some delrin versions, I would like to try.
