Here´s one for you : Ultegra shifter , when on the 7th cog most of the time it works but .. sometimes it does nothing until you get to the third "click " then it engages and shifts , shift down again and it´s working fine . Just had all the cables and covers changed but that was a few weeks ago . Bike is stored hanging from the front wheel ( vertical ) and did not get a lot of use due to familly crisis . any ideas ********************???
