Good point LGF... If bar end shifters won't work properly, it should be possible to grind down the TakeOff plate and either fit a newer thumbshifter version or adapt a plastic Magura type clamp adapter for the old Thumbies - longer bolt needed too I guess) Now that would be cool. Just trying to find a fast 'cheaper' solution for the desperate group all hunting WTB adapters

Pics of what I'm talking about
First pics shows connector base of Paul Component suitable for new style thumbshifter.
Second pic shows Magura plastic old style thumbshifter clamps which should be adaptable with a drill and Dremmel to fit over the TakeOff to allow fitting of XT M730 7speed thumbies.
Third pics shows TakeOff connector base which would need to be ground down and adapted. Maybe it's possible to 'thread' the cable holder piece so you can fit the adjustable barrel adjuster on it...
Just sold my Salsa roller P10/ WTB Spesh bar/stem combo, so will never know. Just thinking aloud
