Maybe the transmission has to work in a little and will get somewhat smoother in a little time? I know my bike felt clunky up shifting when it was brand new compared to the C14. But it smoothed out nicely in short order. I still don't think it is as smooth as my C14 was, but it got much better after running a little bit that I have no complaints what so ever!
Beside you don't need a new bike. You just bought this one to replace the last brand new C14!
By the way, it was great meeting y'all last weekend. Maybe we'll see y'all again real soon!
