Ultegra shifter problem

Hi all

My rear shifters are sticking so when I try to change to a smaller chain ring the derailer does not move but if I hold the top lever while I move the other I get a change.

If anyone has had the same problem maybe they could share a remedy with me.

check for a loose or missing screw at the upperbackside of the levers that hold them together. Check cables and casing for defects. You said rear,then said chainnrings.The rear is cogs.

I had a similar problem with my Ultegra shifters earlier this year. The inner lever would not always catch to perform the shift. If I pressed forward as I deflected the lever inward, it would shift. Since the problem was worse in cold weather, I figured it was due to gunk/grease. I remedied by cleaning out the levers with a degreasing spray and they have been working great ever since.
