I’ve been riding a pair of wheels built around Mavic 719 rims for about 7 years, so they’ve done a lot of miles (although they’ve never needed truing and I’m still running the original set of hub bearings, so they’ve not been abused).
I’ve just noticed a rather alarming crack propagating for around one of the spoke holes on the rear wheel. The one in the image below is by far the worst; roughly 50% of the spoke holes have no damage, the remainder have hairline cracks of about 1/2 cm either side of the spoke hole (the front rim is unaffected).
So I guess I should be looking at a new set of wheels fairly soon (I’m not sure that these could be safely ridden much longer).
Is this an acceptable wear and tear failure, considering the age of the rims or should I be looking at something different to replace them (recommendations please)?
For reference they run with discs but do have V-brake surfaces.
