Hi all I'm having a problem with replacing a spoke on dura ace front wheels. basically I can't get the spoke taut, I've screwed on the spoke nipple with first a flat headed screwdriver then with the spoke key. However even though the nipple can't seem to go any further, the new spoke is still loose in the spoke holes. This is even after I've tried holding the spoke with pliers and continuing to tighten with the spoke key. The spoke is in fact becoming twisted by doing this. Is there a step I've missed on?
