I bought an Origin 8 threaded to threadless adapter, as seen here: http://www.amazon.com/gp/product/B0037N6PEC
The stem I have is: http://www.orbeaproshop.com/products...=18&product=63
I'm having issues with the stem rotating on the adapter.
Since the stem is carbon, I don't want to just crank down and over-tighten, so was wondering if any anyone had advice on how to roughen up the aluminum (just sandpaper?) or any other advice on how to give these components some traction. Thanks!
