Hi,
I've recently bought an unused rear derailleur from ebay (Shimano M430 Alivio). When I received it, I noticed the 2 pulley wheels aren't parallel with each other. It seems odd to me, is this right? Also, the bottom of the cage splays out, but it might be supposed to be like this to allow the chain to run out from the largest sprocket to the largest chainring. Photos attached.
