+1 a mate of mine had a new bike from Halfords and the FD was so high it wouldn't shift onto the small ring at all. It was about 10mm rather than the 2-3 recommended. Moving it down fixed it.Brucey wrote:is it my imagination or is the FD well above the big ring? If so, that won't help downshifts.

Of course it is. Even over the pond? I got "rat tail" in my mind, and couldn't get past it.

No - must be a trick of the light. I've since taken both middle and big ring off, had a good look and found no swarf of any kind. Nevertheless, while they were off, I filed anything that was slightly rough to my bare fingertip. One thing I do think is significant. The finish on the middle ring is not smooth. See below. I don't know what to call it but it's a bit like a rough sand casting and the side faces of the teeth have not been lathe machined on either side. Could this be grabbing a little, intermittently?
