"Benchmark stem for Trail / All Mountain / Enduro"

Dr. Duncan "Om" MacDougall was an american doctor from the early XX century who was determined to measure the weight of the soul, determining after several experiments it was 21 grams.

At AMS we were as obsessed as Mr "Om" with the weight of our state of the art stem, so decided to name it "Om". Coincidence or not, Om 45 stem weights 121 grams.
