hey guys,
So I got a mid-80s daccordi frame that I figured my campy record (1990) bottom bracket would work with, but that's not the case. Before bringing it to the shop, I just tried to thread it into the shell so I could just carry it in like that, however the bb diameter is too small-- it basically just falls into the shell.

I don't know much about bottom brackets and I'm having a little bit of trouble learning. The dimensions on the bb are 1.37 x 24t, which is english correct? And this would also make the diameter smaller than my italian bb shell?


And if this is the case, any new bb recommendations would be appreciated (I have the whole 1990 record titanium group, so the new bb would have to be compatible with the same cranks as this one).

Again, thanks.

It certainly sounds like you have an English bottom bracket and a frame with an Italian bb shell. You may be able to find Campy Italian threaded cups for your current bb. Otherwise any ISO square taper Italian bb of the correct spindle width should work.

actually I think while the overall lenght of the spindle would be the same, the spacing between the bearing races is different between english and italian. if you are in a hurry you may have to replace it. you can't buy it direct but you bike shop might be able to get you a C Record BB from a company called EuroAsia imports. I used to deal with them alot for Campi parts.

Thanks guys!

Bianchi Girl: Do you really think I need to go with c-record? I was just hoping not to need to spend that kind of money. You don't suppose this or this would work? Also, Phil Wood has the 68/70mm with the 102mm spindle as well.

I was surprised to find that the spindle length on my bb was only 102 (101.9)-- that seems unusually short for a 10speed no?

Thanks again for your help with this guys!

Also, I thought the rear spacing on this frame was 126.2, but I just had it measured at the local shop and they tell me it 125! ! Any idea where I can find a 10spd compatible rear hub with a 125mm spacing? Does that even exist? Wouldn't that make a 7spd fw the max?

what kind of BB and crank do you have? you said '90 Record and that is C Record right? one blind chainring bolt? any BB witht he right length and taper will work

is this a steel frame? if so you can get it 'set' to 10spd spacing. if 126.5 / 125 is not a big difference to begin with. but a 10spd wheel will fit in your frame with a bit of elbo grease

1990 Record Ti? do you have pics?

The difference between 125 and 126 is well with in many frame builders tolerances and is meaningless.

Yes, 126 is 6/7-speed spacing and, no, no one makes an 8/9/10-speed hub to fit 126 mm dropout spacing. You can put a 130 mm hub (8/9/10-speed spacing) into 126 mm dropouts one of two ways:

1. Force. The width difference isn't that much and most 126 mm frames will accept a 130 mm hub with only a minor struggle.

2. If the frame is steel, you could have the frame "cold set" (read bent) to 130 mm spacing and then it will accept a new hub with no effort. You shouldn't do that with an aluminum frame and it's absolutely not to be done with carbon.
