Wait, what? A plastic knurled edge flush with the arm is a hazard? GMAFB. Just look at the pic above of that after-market cap, and I wouldn't even have it protrude that much, nor would I make it 7075 Al, just plastic. And even further, the pinch bolts are what hold it on, the cap is just to adjust the preload. Get rid of it altogether. Make the cap a tool to adjust the preload that comes off and stays off and just include it with the crank. And this brings me back to my first point, why not just include the plastic tool? It is a cheap piece of plastic.
It may be a 20 year old design, but it is a pretty poor one.
