I'm looking at these in lieu of Campy Record BB which was not that highly rated in Roadbikereview. I did do a search of them on this forum, but that focused more on their carbon stuff. I'm considering the model with Ti spindles? Are they safe? I know that's an age old debate, but that was more for pedal spindles. I just want a reliable smooth BB. Thanks for any input. Ernie |

Ernie What's wrong with the 102mm Record BB? I have installed many, many, with no problem. Long lasting, smooth...MUST prep the frame tho-face/ chase..something I'll bet many of the RBR clones didn't do. As for a ti BB spindle...BAD idea. Plus, are 'Token' BBs ISO/102mm? Do they have decent bearings or crappy ones? |

I second Peter's comments; I have three Chorus BB's (which are record without the carbon) and the oldest of which is 7 years and tens of thousands of miles and continues to turn smoothly. Is that reliable and smooth enough for you? D'ohBoy |

Just good design and materials. Nothing exotic for a bike rag hack to wax elequent about. I have installed many, many, with no problem.

That frame prep stuff is for grunts with dirty hands, not the masters of the keyboards. As for a ti BB spindle...BAD idea. Plus, are 'Token' BBs ISO/102mm? Do they have decent bearings or crappy ones? Bearings? Who cares!?! It's TITANIUM, man!!!! |

Its sort of like that old J-in-the-B commercial, "You get rid of that bun and you got something..." |

I did an autopsy on a campy record bb that was trashed. Ti axle,
aluminum cups, carbon spacer. The bearings were, well totally inadequate for the appliation. 2 cartridges on 1 side that had way too small balls in them. Maybe 1/8". It was hard to tell since everything was ground to metal dust. Both the inside and outside races were busted up on all 3 cartridges. But hey, the ti axle had gouges and wear groves but it's the only part that wasn't totally destroyed. I'd say the probem was making the bb out of too many parts, undersized bearings, too many bearings. Hard to beat a standard shimano bb. Another problem with this campy and few other bb's is using more than 2 bearings. You will get some flex in the axle and trying to flex an axle thru multiple bearings puts loads on the bearings they were never designed for. A single bearing can handle the anglular changes just fine. Rick |

I've personally trashed two Campy BB's, one Record and one Chorus.
The outer bearing on the driveside ground to little, bitty shards of metals. Seemed to happen at about 10,000 miles. I'm a big guy and put out some watts and do lots of sprinting, but I would expect more from Campy. The last one disintegrated while I was in France with my family and I discovered just how unpopular Campy stuff is in southern France. That said, I shelled out the bucks and got another Chorus BB; I just couldn't see parting with my beautiful Record carbon CT cranks. They are works of art. I'll be ****ed again in about 6,800 miles... chris |

Yes, it does come apart and you have access to the bearings. That said, I also noticed a minimum amount of grease that was used. I went down to my LBS, they gave me a grease that was compatible with the Campagnolo grease (white grease) and I repacked the bearings. She doesn't ride very often, actually laid off the bike for about 3 months. When she did start riding again she complained about a clicking sound in the bb area. I checked if anything was lose, then put the bike on my stand. Sure enough a clicking sound, but as I turned the crank, the clicking sound slowly disappeared, thinking the grease had to circulate. After 3 years, I checked the bb again, about a 5000 mile check. Sure enough the bb needed grease again, and hopefully good for another 5000 miles, we'll see. -tom |

" wrote: I did an autopsy on a campy record bb that was trashed. Ti axle, aluminum cups, carbon spacer. The bearings were, well totally inadequate for the appliation. My 12,000+ km on a 2000 Record BB says otherwise. This was not on a "comfort" bike either, but a training/racing bike that led a hard life. It's still extremely smooth. But hey, the ti axle had gouges and wear groves but it's the only part that wasn't totally destroyed. I am not aware of any Campagnolo Record BB, that has the 3 cartridge bearings design, having a Ti axle. My understanding is that it's hollowed (hallowed? ) steel. Another problem with this campy and few other bb's is using more than 2 bearings. You will get some flex in the axle and trying to flex an axle thru multiple bearings puts loads on the bearings they were never designed for. A single bearing can handle the anglular changes just fine. Can you please explain why a two-row bearing arrangement is bad? How does the flex in the axle put unacceptable loads on the second bearing? |

Now we're wondering - since you apparently don't remember who was that maker of that BB that you diagnosed - why should we trust anything ELSE that you wrote in your message ?? - Don Gillies San Diego, CA |
