I'm replacing the front mech gear cable and I've got SRAM X.0 shifters. Getting the cable end into the shifter was easy enough but I can't get the darned thing out! Is there a trick to this. It's well and truly stuck in the shifter housing and any amount of wiggling the cable to and fro, just does not seem to release it. Is there a trick to extracting gear cables. I've tried the twist grip in all positions 1-2-3 and I can see the cable end but it's buried too deep in the guts of the shifter to try and winkle it out.
