• 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.
