With the bb30 and pf30 being infamous for it's creaking, I sought out internet reviews for a pf30 bottom bracket that didn't creak. This was the only one that had consistent reviews of it not creaking. There's something to be said when you don't have to worry about your bike and you can just focus on your ride. This bottom bracket it does that for me. A bit pricey, but you end up getting the quality you pay for in my opinion.
