constantly dealing with customers in our bike workshop having "issues" with BB30, PF30, OSBB and all the other crappy press fit standards
most issues relating to re-occuring creaking, rough running bearings, or failed bearings often in a short period of time after purchase
I've gone through 7 pairs of bearings in my Stumpjumper's PF30 BB in the past 2 years and I only ride 1-2 times a week and never jet wash my bike! Thankfully my SRAM cranks with their 30mm axle have finally worn out...
..tomorrow I'm installing a Praxis Works BB convertor and Shimano XT HT2 crankset in an effort to banish this ongoing press fit nonsense
thank god my road bike uses an english / BSA threaded bottom bracket shell, as that bikes sees some serious mileage
the best advice I can give being constantly at the "blunt end" of this nonsense is to install all the components with loctite, anti-seize and re-pack the new bearings with quality waterproof grease before installation
