I read on this forum or somewhere similar that the SRAM mountain bike shifters and RDs (pre-XX) use a different amount of cable pull in different parts of the range. The pull ratio may however stay at 1:1 throughout. I never understood it fully, and have not had the need to try mixing the MTB and road SRAM stuff to see if it really makes a noticeable difference, but I would be interested to know if anyone has tried it.
Of course, the question is now whether XX will remain different from all the other MTB groups in this regard or whether the other levels of SRAM MTB components will start to adopt the road and XX standard over time. The reason for making them different in the first place eludes me; as does not offering a triple road shifter and derailleur - Truvativ (one of SRAM's brands) already make the crankset for it, the Rouleur triple, but you can't buy any SRAM products to shift it with (sorry, off topic rant now over).
