These vids were taken this morning to provide examples of my mysterious shifting problem. Please view them....and maybe I can get to the bottom of this issue once and for all!
The problem: Delayed shifting, or no shift at all, or a double shift. Can set cable tension to shift either UP or DOWN, but not both. Video #1 details the struggle I go through to make a simple shift:

The temporary solution: If I route the cable under the rear axle and secure it with zip-ties...everything works. Video #2 is a good example:

The LBS tried twice to repair the problem....all cables and housings are new.....Ultegra group is fairly new and was removed from my LeMond in perfect working condition.
