I have a new bike on order and already have upgrade syndrom. The bike is well speced 1x11 except the shifter and derailleur are Sram NX. The cassette is GX driver 10-42. I have ridden NX and it works great for it's price range but doesn't compare to the crisp but firm feel of the X9 on my fatbike. How far up the Sram 1x11 chain would I have to move up to get the feel of my X9? I know my current X9 features ball bearings in the shifter, what level 11 speed would have ball bearings in the shifter? I was thinking X1 or X01. I figure GX wouldn't be enough of a step up and X01 is at the top of my budget. Any feedback would be appreciated!
