The page describes this as an aluminium alloy, copper, and finally, in the description, brass. Which is it?

Looks like a mix to me. It's well built and easy to use and puts out a good ring

Should this be mounted on the left or right on a mountain bike?

I believe the best answer to the question whether the bell should be mounted on the left or the right on a mountain bike …is “yes”.
