Hi, my old 8 speed shifters are intermittently faulty. When they are pressed there is sometimes no engagement click and the gears don't shift. The bikeshop says that these Shimano shifters are not repairable.
So, I would like some shifters, or even a whole groupset of more modern type (9 or 10 speed) Shimano ultegra or 105 (even dura ace hehe).
cheers
Adrian
