I have a SRAM PF30 pressed in my NeilPryde Bura SL and when I sprint or climb (i.e. any time I add a little power…) is squeaks to no end.

My wife's new Parlee has the HSC PF30 which is dead silent… Is there a way to quite down the SRAM, or should I just bit the bullet and pull it out and replace it with another HSC?

Loctite 609 and primer activator....do a search on this forum and you will find several threads outlining solutions to the same issue you mention.

would also like to know if 609 will cure on non-metallic surface. pf cups are made of derlin, and BB shell is carbon

Some are aluminum, like the ones that came in my EVO.

This product looks to be a definitive remedy your issue: https://www.kickstarter.com/projects/96526853/bbinfinite-the-worlds-fastest-bottom-brackets

Check that your pedal threads are lubed also......I spent quite a bit of time trying to remedy a squeaky bb only to find that I forgot to lube my pedals.

I'm yet to see what the (expensive) primer actually does. It seems to just flash off before you apply the 609. I tend to think a wipe with acetone would be just as effective.

The activator/primer contains micro particles of copper which accelerate the curing of the 609 when it's applied to an inert surface like plastic or carbon fiber.

I can't see any reason why that set up would cause noise as long as the bearings are relatively fresh. I would recommend you get the bike upside down and carefully inspect the underneath of the chainstays at the bb end to look for cracks.

^ Very true, but recent experience would lead me to carry out that check in this particular instance.......

Thanks all. It's definitely the BB. The threads on the pedals are lubed (always do that when I install them), the skewer is a Mavic Ti skewer that I've been using on other bikes with complete silence. And the bike only creaks when I stand or sprint, no other time, i.e. only at max side load.

The BB did press in extremely easy, so I'm thinking a combination of ever so slightly oversized BB shell and ever so slightly undersized BB cup. I'm going to replace it with an aluminum BB instead. HSC makes a great BB that I installed on my wife's Parlee Z5SLi.

There are so many claims of creaking bottom brackets that turn out to be creaky rear skewers that's it's not funny.


I'm guilty of tearing down a BB, searching for a creak (multiple times), when it was just a Zipp skewer.
