Posted on 24th, September 2011 about Zephir Stem
Bit too much material cut away in the shaft clamp area, if you ask me. When torqued to just 4Nm, the bolts bend (plastic deformation), even though they are pretty short. Not a good sign. I don't really trust that stem now for real AM usage. But could hold up fine. Who knows. And neat looking, that's true.
