Picture says it all.
The threads on my carbon fiber crank are completely messed up.
Instead of finding and reading a manual to remove the left crank of an FSA SL-K crank, I read a blog post instead that was wrong. I hung up the screwed up crank where I can see it whenever I do work on my trikes and bikes.
Dana at Bent Up Cycles ordered me a new left crank for $130. Better then buying a whole new crank set for $500.
