Been adjusting my stem/spacers today, I must of over tightened one of the stem bolts as its rounded off the thread inside the stem :(

Do I need a new stem now? Cheers.

    Part of me says yes as it could be dangerous and its a good excuse to get some haribo (it was wiggles fault, right?)

    But the sensible part of me thinks of one bolt can manage then its fine. Assuming its not a carbon steerer thst you are fixing to ?

    Not an issue if steerer is carbon or alloy.. the stem bolts just clamp the stem into position and light torque only needed to stop it moving... nothing structural with the headset etc.
    You could try just a cheap tap and die set to re thread or get lbs to do it... 4 or 5 mm ? A set is handy enough for the tool box anyways.

    Dont go one bolt though.

    Exactly. Deda stems require quite a high torque - about 8nm, but most stems only ask for 5-6nm. It's really tempting to do it up as tight as possible, but it's safer to do it to the correct torque; same with the bars.

    I have no idea what's going on here.

    Tighten it up till the thread strips, then back it off half a turn. :-)
