They are for pro racers, who can put between 500 and 900 watts of power through a drivetrain. Mere mortals like us typically can't create the sort of twisting/torqueing stress on gear that separates the expensive, high-end stuff from the rest.the differences between x7 and xx arnt that drastic
Having said that, even I can tell the performance difference between XTR and XT shifters...
Pro riders don't ride the best gear because it's expensive. They ride expensive gear because it's the best.
I have a suspicion that Zoom's actually right - if it moved less cable, it would be relatively less tolerant (0.1mm is 10% of 1mm, but it's only 5% of 2mm), so what you're saying doesn't mathematically make sense.AngoXC said:Close but the other way round. SRAM operate off a 1:1 ratio so for every one "unit" of cable that gets released or pulled, your derailleur moves the same amount (so less cable movement than Shimano).
