On the contrary, Eddie at ESR told me it is a USA made cylinder. He said everyone tinks by it being so cheap that its not. He said he is buying straight from the foundry. (I think I spelled that right) I just ordered mine, should be here in a few days. Can't wait to get it installed on my bike.........which will be around March.
