Principia carbon fork question, does anyone have one with an aluminium sleeve insert glued in the fork? Mine does and it reduces the size to an internal dimension that won’t take any other 1” size. Unfortunately the FRM headset it came with appears to be buggered, always coming loose, and I’m looking for a replacement. Problem is it appears to be a 1” aheadset / compression bung that is impossible to find/ replicated by any other manufacturer. Any advice appreciated?
