help with PF30BB adapters/BB options

[Dave B]

I have a normal sized spindle SRAM red crankset typical not a BB30 diameter. I want to put it into a pf30bb size in my cross bike and understand there are a variety of adaptors that would work just fine.

I already do not enjoy the pf30 creaking, so need a bit of advice/guidance.

Have any of you had any luck with either adapters to fit a normal spindle on a sram crankset into a pf30bb shell or a pf30 bb that has a smaller inner diameter to take a traditional sram spindle? I would gladly get another bb and press it in with a bit of lock-tight to help with the creaks, but any success stories as to which one is decent?

Thanks all

What do you mean by "normal sized SRAM spindle"? Are you talking about GXP? Is it designed for a threaded BB? If so, I've used them in BB30, not PF30 BB's with no creaks. I used the Wheels adapters. I suggest that you try the Wheels or Praxis conversion BB's. Installed correctly, they are silent.

Another vote for Praxis or Wheels if you're talking GXP spindle cranks.

I have a new Wheels with ceramic bearings I'm not going to use if you want a nice one (PM me if you're interested).

yes everything you said, GXP spindle not anything larger. Need to fit it into a PF30BB shell/BB.

Wouldn't mind putting in a new BB as well.

This looks like the ticket.

Threads in to help reduce creaking and set up for GXP spindles. Anyone tried one of these with success?

I have the Shimano version on two bikes. Works like a charm.

excellent thanks!

If installing yourself just keep in mind that you will need the bottom bracket tool with the larger diameter/16 notches (FSA style). I use Park Tool BBT-29.

Also, for what it is worth, I use the version with the angular contact bearings, which I believe costs $25 more than the version you linked to. I am sure they both work fine, but I have found mine to be the smoothest BB I have ever used.

this. ran Praxis one for a couple years and it was perfect.

but now I'll only buy a BB/PF30 frame if you put a gun to my head.

Another vote for Praxis/Wheels Mfg.

I've had them on two different bikes now.

If I recall correctly you'll want a second BB wrench for installation right? (Hold one side while tightening the other?). Maybe that's just for the Praxis and not the Wheels Mfg.

Technically, yes, but I have gotten by with one with no issues.

[Dave B]

So you need two of the BBT-29 tools or just one of them to tighten?

I have a specific tool for XTR 980 (which should work) and the BBT-9 so I might be good.

[fa63]

Ideally, you should have two BB tools so that when you are tightening the non-drive side cup, you hold the drive side cup in place so that the BB doesn't spin in the BB shell. That said, I have never had that issue using just one BB tool.

Your BBT-9 tool won't work; it has 16 notches for Shimano Hollowtech but it is too small in diameter to fit the Wheels Manufacturing BB (which is 48.5 mm OD). You will need the BBT-29 or similar; you can also buy it directly from Wheels Manufacturing:

I just grabbed the park one on the cheap. Not too bad. Thanks for the helps gents

just as a note: if you're going from the C-dale BB30A to Shimano/SRAM cranks the ONLY BB I've found to do that in one step is Kogel.

BB30A being a different shell width than standard BB30
