Fortunately there’s a very simple and inexpensive solution: Finish Line Fiber grip can be applied to carbon components to add that bit of friction that’s required to prevent slipping without over-tightening, all without corroding or otherwise damaging your expensive carbon bits. It’s $12 well spent and we’ve got plenty in stock.
Do you have trouble with carbon fiber components slipping? You’re not the only one. Carbon fiber components are inherently smooth and stiff and are difficult to tighten sufficiently without the risk of crushing the fibers and seriously compromising structural integrity (especially when dealing with components like the stem or seat post clamps).
