I beg to differ. I currently have >17,000 miles on the cheapest ISIS BB in the world, a Nashbar unit I got for $19. That would carry you across the TransAm route 4 times!

You can (or eventually will) get duds on any of these cranks and BBs. You can get good ones too, if you're lucky or persistent.

I go with what works and is inexpensive, and sometimes this turns out to be gear that was misunderstood, misused, and eventually displaced by the next greatest thing. This doesn't preclude the older tech from still being useful, or even excellent, to certain users in certain applications. I've had generally good luck with ISIS, despite 3 dud bottom brackets from FSA, Race Face and SKF. I got 22,000 miles on a single Truvativ ISIS BB, sadly long since discontinued. And now similar performance from a BB that from all outward appearance should be a total piece of junk.

This whole argument is practically moot since no one is selling ISIS cranks anymore. You'd have to look long and hard to find a decent NOS ISIS triple crank.
