Chromag Ranger starts at 40mm and comes in 1.25". But retails for $150. I am in this same boat with my 2014 Trance SX. Very frustrating. I have ordered a Transition Temple Lite 1.5 and am jack a machinist friend try to make me a custom aluminum shim. Look for a thread with my results in the next week or two.
link for the chromag stem? I have looked at them online but they dont specify the steerer diameter
