A couple of years ago I purchased the Turbine stem because of its lightweight, clean looks, and advertised "AM strength." What I discovered was that 2 out of 3 held true. I cracked the faceplate on this stem. I always use a torque wrench when installing the bolts, and always apply grease, applying torque in a cross pattern. In addition to the plate cracking, it seemed like the stem as a whole is a bit under built for all-mountain riding. The good news is, it has a lifetime warrantee. I didn't want to go back to the Turbine but was allowed to get the heavier-duty Atlas stem. In my experience, for about 40 grams in additional weight, it's worth the added security to have the Atlas.

A Great DH Stem Atlas - Apr 23, 2014

This is not your typical DH stem guys, and here's why: 1. Ridiculously small and light for the application. 2. Corrosion protection on the hardware is super nice. 3. The tolerance on the stem threads is perfect-torquing hardware is even and balanced. 4. The bolts are small, but are of higher quality material thus achieving a lighter weight. 5. The laser etching is phenomenal.
