Bars and Stems

[Ste T.]

I have recently changed my bars from flats to butterfly as I suffer with my back after prolonged periods on the bike. So far, for the most part, I am very happy with them. The only problem was when I first fitted them, the very nature of the bar shape meant that the grips and levers were now about 2 inches further back than they were with the flats. I all but solved this by moving back the saddle, but it still feels a tad too cramped.
Now to my question. Can you get an extra long stem ( how long ) and how are they measured? Is it literally from end to end or from the centre of the bars to the centre of the head?

Thanks
