My wife's bike has Ultegra 9 speed shifting. During a ride on Saturday the bike developed a problem where she couldn't get the rear derailluer to shift into harder gears. When she brought the bike home and I put it up on the stand I figured out I could get it to go in to the harder geas in the back but I had to pull on the larger brake lever while I pushed on the shifter lever. If I just pushed the shifter lever without applying pressure in the opposite direction to the brake lever then the shifter would not click into the next hardest gear. It seems some play has developed in the shifter/brake combo. How is this problem solved? Is there something that needs to be tightened? Thx.

the exact same problem. I took it to the shop and the mech flushed it out with tri-flow and then shot some grease into it. Rode away as good as new.

When I got my 9-speed shifters, the rear came out of the box exactly that way. I sent them back (no help to you I suppose).

Check the cable for fraying at the shifter side.

I had the same problem this morning. I think a screw or spring fell out as something hit me in the leg. Took it to LBS for a two week vacation. I think this problem is pretty common to the ultegra shifters. I'm pretty sure that this topic has been covered here before. My shifters are 2001 model with around 2000 miles on them.
