Couple of of quick ?'s regarding the new XX cranks. If I am installing on a hardtail 29er (Felt Nine Team) what Q Factor crank would I need the 156mm or the 166mm? Any way to quick check? FYI have the '10 Noir crank and it seems like there is pretty good clearance.
Question #2 - do I have to use the XX front der and shifter? Bike currently has the X9 Front der and XO triggers - can't I just set the limit screws up to block out the 3rd shift? Rather not spend even more money if I dont really need to - really just want the XX 2x crankset...
Thanks for the help
