I have Grip Shift twist-grip shifter and I need to replace the cable. When I pulled the old cable out, I noticed that it went in the side of the shifter and then curved sharply down to the where the cable housing attaches. Now I can not get the new cable in. A couple of times I was able to push the cable into the shifter, but it never came out where it should. I can't see any way to disassemble the shifter. I can look into the hole and there is a tiny place for a cable to go but I can't get it to bend that way. Does anyone have any idea how to put the cable into these shifters?
