    Custom SRAM S-1250, 7050 alloy arms, 10-speed XC double, PF30 spindle, 15.5": 170mm, Others: 175mm
    CHAINRINGS

    I'm doing the same thing with my Stumpjumper. Your crank was 2x10, correct? Did you need single speed bolts or bolt spacers? Or, did the original bolts suffice?

    I have the same crankset. Just take out the the 2 original chainrings and put the new one in place of the 38t chainring. No different bolts needed. You won't even need to shorten the chain if you're using 11-36 cassete and a x9 10s medium cage deraileur (im my case)...
