On new Shimanos like Spheros, Gosa, Twin P and Stellas, are the drag washers pregreased carbon fiber? If not would they benefit from some Cal's?
As far as I know, they all come with greased carbon fibre. I know the Gosa, TP and Stellas do. Spheros, at least the larger ones have carbon drags.
I would leave them alone until they need a service.
Thanks!
