pic as requested. its a bit embarrassing to share, since you can see the wear that resulted from a lazy attempt at chain alignment using spacers. im guessing thats why it cracked. not looking for critiques on that, but more advice on whether to replace the crank. mind you, im cheap, and its been fine for the last while. the other bolt mounts are fine.
crank is a truvativ elita, was on a fixed gear but now single-speed, id say its about 3.5 years old.
