dodgy back wheel on sharp turns?

    I have Alex DA22 25mm wheels on a road-leaning hybrid.
    I judge how good they are on the back wheel, as it's the one that suffers the most.
    I have a back carrier but haven't really put any load on it, eg. no panniers.

    I'd like to thiink that this back wheel could take panners, but I've had trouble with it, twice the spokes have sprung loose (without snapping) and I've tightened. Over all I'm lacking confidence in it and am looking to buy a higher end back wheel.

    The latest thing which tells me it might be close to failure is turning sharply. I like to do this on the left turns, but what's been happening is that there's a buckling effect, where the wheel seems to give at the sharpest point, as if it's about to cave in.

    But is that natural? After all 25mm is quite thin, and the turning angle is fairly acute. May be it's a natural effect of having all the weight on the very outer edge of tyre.

    On the other hand, maybe I need to pump up the wheels a bit more.

    And on the other hand, it's not natural, and the wheel is a bunch of crap.

    Any thoughts for those who've reached this far without falling asleep?

    Sounds like the spokes are under tensioned. Spokes should not come loose if they are tight enough. Find a wheel builder that specialises in wheel building and get them to retension your wheel. I used to own a bike shop and found bought in wheels were very spongey and prone to loose spokes. My mechanic was an excellent wheel builder (and mechanic) and had a strong following of racing cyclists.
