Planet X Model B wheels - a mysterious problem

I know all about the cheap/light/strong bike component conundrum so I was never expecting these to be bombproof, but I'm wondering if anyone else has had the same problem – spoke nipples repeatedly coming off the rear wheel.

It happened for a third time today. I was setting off from lights, standing in the pedals but not really pushing with loads of power, when – 'Ping! Rattle! – another spoke comes loose as the nipple detaches and starts rolling round the middle of the rim.

My very reputable bike shop has re-attached spokes twice and tried to tighten everything up, but to no avail.

I'm using the bike for commuting but it's not being thrashed and I'm a pretty light (67kg) rider who never breaks wheels. let alone frames.

What do I do? Give up and get a new back wheel? If so any tips for a similar/less weight (950g) wheel which might be a bit more robust and won't cost vast sums?

In the interim I'm going to email Planet X to ask what's going on....

    How long have you had them? Alloy spokes corrode so when you replace one, another one will become the weak link and break.

    I've only had the wheels a year and they're used more or less entirely in the dry (I've got another bike I commute on when it rains). Wheels are completely untarnished.

    All three nipples have come loose within the space of a few months.

    Have you done a search on here? I was looking for a new set of wheels around the model B price range recently and I read a thread where someone else had a very similar problem.

    I'm a big fan of the Model Bs so it pains me a little bit to say that I had my latest back wheel last no more than 1000 miles over last winter - several cracks in the rim around random spokes, with most nipples also corroded. I don't know if the two things were related. It had to put up with some rough roads but I don't remember subjecting it to (several) rim-cracking pothole impacts. Planet X replaced the wheelset under warranty so no complaints there.

    Got some Open Pros now.
