I built myself a bike (well, it's probably more accurate to say that I assembled a bike) a couple of years ago.
I found some Mavic Cosmic Elite wheels in eBay, and fitted them.
All was OK until earlier this year, when a front spoke nipple broke going over a bump. Since then I have had a rear nipple fail, and yesterday another front one popped, this time on smooth ground just as I was setting off.
I have a sneaking suspicion that Mavic didn't actually build these wheels. As far as I can see they don't offer a through-axle version of the Cosmic Elite, and it seems that the spokes should be bladed too.

Also oddly, the barcode and part numbers draw a blank on the Mavic site.
So, I am wondering if the wheels have been built up from parts of other wheels (Maybe real Mavic parts, maybe not?) and maybe with too-high a spoke tension? I am no lightweight (85kg) but haven't really done that many miles (7 mile commute, about half the time)
Is it a daft idea to replace the broken nipple and then give each spoke a half-turn to reduce the tension?
