Anyone else heard anything like this?
Yes. In 1997 somebody said Octalink was the new BB standard. Then in 2000 somebody said ISIS was the new standard. A few years later, BB30 was the new standard. This year, T47 is the new standard.
Oddly, the thing which has never claimed to be a standard is 30×86, which has been independently invented by Rotor, FSA, Zipp and Campagnolo under different names at different times. It doesn't look like 30×86 is going away any time soon, and it doesn't matter whether your frame manufacturer builds around BB30, BBRight, PF30, OSBB, 1.37×68, 36×70, 386Evo or T47 since 30×86 spindles can be accommodated in any of them with the right cups. The only shell standard which needs to be taken out and shot is BB86/PF24.
A pal was telling he'd heard that PF30 standard was being phased out by the industry. Anyone else heard anything like this?
