Jonathan Hoffnaglewrote a review of FSA OS-99 Stem on July 15, 2018
I purchased this stem a few months ago. I like the mat flat finish, however, when properly torqueing the pinch bolts, the ears of the stem are touching. This despite under torqueing to only 4nm not the 6 recommended that I have never torqued to. Before you tell me to look more closely I actually put a piece of paper between the ears and couldn't remove it after tightening the pinch bolt. Expensive and certainly not thoughtfully engineered.
