Odd thing today. When I shifted down to the small ring, the chain (new Campy ultra-narrow) somehow managed to sit between the two rings and just slip while I pedaled! Now, this isn't supposed to be a clutch, so I'm not thrilled about it. Yes, my FD is adjusted properly.
Is this a known problem -- that maybe the new Campy 10z chain is too narrow?
