I got a set for 50$(tires/tubes/cog lockring included) , and put them on my main boo, they survived getting hit by a car(after some serious smashing/truing), and 9 months of abuse afterwards, eventually the rear hub fully siezed while i was riding it(that's what i get for not repacking or even adjusting 10$ hubs), it had those same cheap formula loose balls, the whole drive side of the hub sheered off when i tried to take the cog after it siezed up. All in all 50$ well spent. You can't ask more than that from a chode wheelset off a chode bike. those hubs suck a lot of ass, ****ty, hairy ass. i'm sure you could make the hubs last a few seasons if you repacked them once a month, but who can be bothered with 10$ hubs it aint worth your time.
