    DA 7900/9000 crank arm pinch bolts

    Is there an alternative to use? The seem to be soft and easily rounded out. Yes, that means I spent an hour yesterday drilling one out.

    'brifter' is a lame word.

    Make sure your wrench is in good shape and fully engaged in the head of the bolt. I'm not aware of any easily acquired bolt that has a head small enough to fit. Just be careful. You can easily order replacements.

    Thanks. I got in a hurry and the wrench slipped when switching my power meter arm to another bike. I had replacements ready to go and usually replace the bolts after a couple of installs to avoid the problem.

    You can replace them with the Tiagra/105 bolts, which are *slightly* better.
