Hi everyone,

I have 2010 chorus and it shifts fine gear by gear, but if I am low on the cassette and shift all the way up to a larger cog with one big swing of the shifter, it goes up and then drops back down one cog. If I hold the shifter all the way over it stays in the proper gear, when I let go it drops back down one cog. I tried to adjust the cable, but haven't had any luck. Anyone have any suggestions?

Thanks
