`GG oem shifters have cheap tips but the rest is well made. They don't bend that easily but can be bent back into shape if they get twicked. I've even seen 2 get bent back into shape while they were still on the bike. I've had one aftermarket shifter and it was one of the cheap ones that are sold under various brand names. It might have been the same one I saw recently on ebay (see link below). Anyway the one I had looked great but loosened easily and often on the shaft but worst of all it was way too easy to bend. I like the stock shifter better.
