The Extralite RoadStem OC is the same as the Extralite RoadStem UL except that it is designed for over-sized 31.8mm bars. It is the lightest "non-vaporware" aluminum stem we know about. The body is CNCd from 7075 Txx aluminum, the bolts are titanium, and the clamping mechanism is intelligently positioned so as to not put stress on the back of the steerer. This is particularly important when using a light-weight carbon fork. The Extralite RoadStem OC has a reversible +/- 8° rise and is designed to fit a 1 1/8" steerer tube and standard 31.8mm bars. If you're looking for a stem for standard 26.0mm bars, check out the Extralite RoadStem UL.
