First generation (silver) Rival, but first built up this summer and only about 1000 miles on it. Middle of a ride, shifting fine, dropped to the small ring to ride up a hill, get to the top, try to go back to the big and it clicks but no shift. The cable still has what seems to be full tension, but there is less resistance to the lever. It still clicks, but no trim or shift or perceivable pull on the cable.

I have only peeled the hood back and tried to look around but I couldn't see much and I don't know much about the double taps. Any suggestions on where to start?

Thanks in advance, Steven.
