    Slight cracked stem

    Long story short found a good deal on a stem that I wanted and that would fit me better than my Zipp sprint 110mm and 12deg drop.

    Problem is I noticed there was what seems like some stress cracking or something near the bolts. Seller said he didn’t know and said I could send it back for refund if I wanted. I bolted it on tq’d to spec and no issues jerked on it and put all my weight on the bars clipped in and seemed to hold up fine....I’m about 200lbs. Thoughts? Should I be fine?

    Send it back. There is no such thing as a "slight crack" in a high stress area of an alloy component that is critical for safety. IT shouldn't even be a question.

    Better yet, saw it in half before you send it back so that the clown who sold to you can't sell it again.

    OK, since you have 40 posts, I assume this isn't a troll post. Yes, the stem is garbage. If you like the idea of keeping your front teeth, do not use it!

    Ive contacted the seller and said I want to send it back to him. Guess I’ll fork out an additional 100 for a new one.

    I don't see any cracks, am I missing something?

    NM.... I see them now down inside the mating surfaces.

    I'm surprised you even need to ask this question. A crack is a crack.

    It may be a good deal for your dentist, not a good deal for you.

    Yeah, it's hard to see but definitely a problem. Don't ride it!

    Hard to see in the photo because of the carbon pattern. But it's irrelevant. If you think there is a crack, nothing else matters. Cracks, especially in stress areas get bigger and fail.
    The seller is even offering a refund. It's a no brainer.
