Thanks!

I'm now wondering if the pistons in my mech boxes are plastic or what not. I would really prefer aluminum or the like as they should be much more resilient to the stresses put on them.

Another thing I've been wondering about is what they are lubed with, and how often they should have regular maintenance and what that maintenance is.
