Cable nub broke off and now shifter won't shift...
So while downshifting (pulling the cable) from the 11th to 12th sprocket, my cable frayed and the nub holding the cable in the shifter (Shimano Ultegra) is now somewhere inside the shifter. Right now, the shifter won't downshift and I'm afraid the shifter is broken. Does anyone know if it's possible to get the cable nub out of the shifter? Is there any way of taking this thing apart? I really don't want to have to spring for a new shifter.
