• Does anyone have experience of CODA quill stems failing/being known as death traps? Found this example here, pic below: https://www.lfgss.com/comments/15180272/

    Today I removed the ally handlebars from a CAAD 3 I bought and the edge of the stem clamp has cut a little groove in them - Cinelli Eubios with a reinforced/thick clamp area. I was going to file the edges of the stem a little and carry on. Or should I consign both to a shelf and replace? Both parts are pretty ugly, but they're original and the right fit so I'm loathe to get shot

  • bit late, but in case it helps. looks like the blue bike has a slightly different model stem than yours, which I have here, i'll attach a photo. the clamping area does not have parallel edges like on yours, dunno which came first or which one is more prone to failure, but i suspect they will behave quite differently.

  • Ah nice one, thanks for taking the time to post. Definitely seems like my stem nicked the handlebars because the clamp loosened.

    What I've done to be sure is run a fine file across the clamping edges then covered with gloss black Tamiya model paint.
