Can I use Sram XO shifters with XTR front and rear derailers? Curious.

I am assuming that the 9 speed XO shifters are lighter than the 9 speed Shimano....

XTR front derailleurs will work

rear absolutely not

There is a spaniard that sells an ad-on to convert your XTR rear to 1:1 pull and use it with your gripshifts contact him.
