I don't have my gen 1 anymore, it even did it when the chain was baggy as a whores knicker elastic, but I found that quite endearing once I'd got used to it, the snatch on early gen 2's are a thing of online review legend I've never actually ridden one, the gen 2 I have now is as smooth as James bond after a vodka martini, but all in all a good bike plenty fast enough for me
