Sweet . Looks like you also swapped to shimano levers somewhere along the way? I just put 200mm rotors on my Sturgis. Worth the weight.
Yeah, got a sweet deal on set of XT, there are so many take offs around these days. All my bikes now run XT so I like that they all feel same and bleed is always perfect and takes 5 min. Put 180mm rotor up front cuz that is minimum Mastodon requires, other then that I've never felt like 160mm wasn't enough... there is usually not enough traction to justify bigger brakes.
One thing to be aware of, Shimano's "Wondering Bike Point" issue is actually amplified by cold weather. Not really sure if that changes anything for me, but cheap Sram Level I had stock on this bike never had any performance issues even at -25C. Again I still will take XT over any SRAM just due to easier bleed and perfect result every time, but this is something to know.
P.S. Just realized that I can now finally have only 2 different set of brake pads!!! This is huge, tired of having 5 different spare pads in my tool box
