I've been wondered for a while now how long my set of Velomax Circuits would last. Got the answer last week when doing some planned replacements at 30K miles: chain, cassette and new tires. When changing the rear tire, was shocked to find a substantial crack in the rear rim:
The only thing I noticed on the road was a slight knock on braking, maybe for a couple of weeks. I actually spun the rim while the bike was hanging in the garage and didn't notice anything other that a slight wobble in the rim.
In my experience, 30K miles on a rear wheel (with no truing or broken spokes) is excellent life. I've never gotten that kind of mileage out of my built-up 32 spoke wheels, but they were built with basic, low-end Mavic rims.
