Both of my Ultegra/600 shift levers (circa 1998, 8 speed) frequently won't shift down, particularly when it's cold outside. Both small inside levers move through their full range, but it's as if there isn't enough friction and nothing happens. Is there anything that can be done to increase the friction or otherwise fix the problem?

Thanks in advance. >
Just to exclude most obvious problems, check cables and housings, in particular under the bottom bracket. Then maybe try to flush the levers with WD40.

Move south OR flush out the cable housings, front and rear (or replace) with some WD-40. The Shimano cable lube that comes with the levers when they were new slowly turns into glue. Replace the cable at the same time unless it is reasonable new. Ten bucks and you should be good to go. Bill Brannon
