Ok fair enough. I think I've got it now. You guys are utter gents and have the patience of Job. If you're ever in Dublin I'll buy you all many pints

FYI

Just wanted to say thanks to you all, got my bar shifters installed and working great for my first race of the season last week. Just added a 4-way junction box and got my LBS to update the firmware on the existing components. Now for cable tidy up and some new wheels...
