Last year I put a pair of cable stops onto the bosses that had downtube shifters. Now I want to take them off but they have become stuck and try as I might they won't come off. I did smother the inside with grease before installing.
I've tried spraying into the edges with wd40 where they have come away a bit with all the pulling and also I unscrewed the bolt and sprayed wd40 into the hole. Other than grabbing them with a pair of pliers and damaging them, are there any suggestions for less drastic measures?
thanks for the responses so far. I'll definitely try out the liquid wrench (never heard of it before). As for the long bolt, wouldn't threading it mean the bolt will thread with the inside of the boss?
