While my current crankset’s Q-Factor is 175mm and the chainline is 48.8mm, the Shimano XT 1×12 has a Q-Factor of 172mm and the chainline is 52mm. What, if any, affect will this have on my bike? I’m primarily riding slow tech trails. February 14, 2021 at 15:07 #580781 EastonUltraLiteSimp The best advantages (in my opinion) since you’re riding tech trails would have to be maneuverability. Now you will have a much better lower range to creep through those corners if need be. February 14, 2021 at 18:37 #580927 TechtoFlow Manueuvarability – yes, absolutely. I can certainly see that as an advantage. Is it possible to update to a 1×12 drivetrain and retain a 49mm chainline?
