PF30 bottom bracket on Titanium Frame Help
Who has actually installed a good quality bottom bracket onto a titanium frame with PF30?
Trying to do my homework using a campy ultra torque setup but heard horrible stories of metal on metal surfaces, which will eventually creak. What’s a good bottom bracket and your experience would be greatly appreciated. I’ve heard good things on bottom brackets by SRAM and FSA with the plastic cups but I’ll have to use a different non Campagnolo crank. |

I know you and I discussed by PM regarding this but I wasn't aware that you intended to run Campy. Eventually creak may be a year or two down the road. If you get a year or two out of a metal on metal interface and have to redo it with new Campy cups (they're like $30, aren't they?), is that a big deal?
I'd just get some Loctite 609, use the activator stuff and press the cups in and forget about metal on metal contact until that day comes where it does creak, if ever. Hell, if you want to stop by and the cups are ready to go, I'll do that for you (not going to assemble the bike further but I'll get the cups in), just bring me a six pack

Nice offer Ryan!
When the day comes to replacing the cups? Will it be difficult to knock out the old cups with loctite? Last edited by corkycalvin; 12-09-2021 at 12:02 PM. |

I've got a King PF30 on my Form Ti mountain bike. No issues at all, I flush it out with the King grease injector tool occasionally but it's been in there for 8ish years without a sound.

Or 222 Purple and 'Maybe' if ever, consider it a service to remove/clean/222, re-install if/when the creak surface. The UT/PF30 cups sure have a lot of surface area I noted on my install on steel PF30 frame.

Check out the PF30 adaptors for Campy cranksets at wheels manufacturing:
https://wheelsmfg.com/products/bb-cr...-adapters.html Currently out of stock though. I’m using a set on a PF30 frame with Sram GXP cranks and the interface and operational quality are superior thus far. Only unknown is durability as the adaptors are made from some sort of ultra high density nylon. |

Wheels MFG thread-together bottom brackets are great, if you want to run Shimano/Sram/FSA/anything but Campy.

Regarding the Chris King BB and the Wheels MFG, I've had both of those creak eventually on different frames. On my T3, I checked the PF30 spec and measured my shell the best I could with calipers and my shell was on the tight side of the specs. I checked the Wheels MFG BB and it was undersized (outside of spec).

A correctly installed pressfit Campy UT BB will likely not creak unless there's a serious tolerance issue. Clean shell with alcohol and install with wicking loctite. +1 on the Wheels MFG thread together BBs too - have a couple on my bikes and never an issue, installed raw no less.

Can you get your PF30 shell tapped to accept a T47 threaded bottom bracket?
That might prevent a lot of potential issues.

I think it worth mentioning, Press fit BB shell in material that is welded more likely than molded [carbon] to be distorted from heat of the process???
Tapping/facing etc seems a good last process before installing a BB in a welded shell...
