Campy BB Question

[msl819]

I need a square taper bottom bracket for a Campy Chorus crankset. It’ll be going on a Serotta CRL. First question - do I need a 102mm? Second question - should I just stick with a Campy BB or look for the likes of a Phil? It’s been a long time since I bought a square taper BB. I’d like to just this on and not have to think or worry about it.

Crankset from the last 25 years? Campagnolo Chorus bottom bracket 102mm. A lot of online places have them pretty reasonably priced. Phil Wood it's kind of pricey I think for not a whole lot more functionality.

Yeah but the Phil wood is the closest thing to 𝐒𝐞𝐱 in a bb. It’s worth it.

If youve got money to burn get Phil otherwise just get a Record or chorus 102mm bb

[msl819]

68X102mm, right? Any good online sources?

Which Chorus crank? If it says 'Campagnolo' on it, not a shield stamped in there, it's 1995 and later and uses a 102mm ISO, symmetrical BB..

If 1994 and older..111mm, JIS, symmetrical.

Yup, Campag or Phil..

Last Chorus using a 111mm, 1994..25 years...1995 is 24 years..:eek::cool::):p

If you stick with the Campagnolo BB, you have avoided opening the can of worms of matching the taper dimensions. This is one of the reasons that I try to match the the BB to the crank with the same brand, time period, compatible range, etc......

The Chorus/Record 102 BB lasts a long time. I don't ride in rain, and I've never worn one out from riding.

Agreed, I have two Chorus BBs that have been in use for over 10 years and they are still perfect. Again, I only ride in the rain when I get stuck. The UK vendors like Chain Reaction or Wiggle have them for a nice price.

Stick with Campy bb, great price, product. The Phil is great but pricey, save money for other stuff.

Campagnolo Centaur square taper will also work on the older cranks that need 111mm.

The only thing wrong with the Campy ST BB is the cheap plastic retaining ring that is prone to stripping out. Both Phil Woods and Campy internals are great but the steel ring of the PW BB is far better. I vote for PW.

IIRIC correctly, current Pista BB is 111.

PW have poor seals and I have had bad experiences with 4 of them before I switched. Not to mention the proprietary tool (or two of them) that you may need to bring with you on travel as few places have them.

Stock ST campy or shimano for the win.

Plastic retaining ring? Don't recall such a thing - threaded interface between tool and BB is aluminum on mine.

The pista bb is asymmetrical. I don't think it will work.

No such animal on Record/Chorus(or Centaur) BB cups..plastic cup, thems aluminum.

[oldpotatoe]

No..it is a 111mm version of the road, 102mm, BB and is symmetrical, like the cup and ball, CRecord SPc...’strada’, ‘pista’ Costa.
The Record and Chorus TRIPLE BB was 111mm and asymmetric. You can use the Centaur BB on pista cranks, no problem.
102mm, ISO(NOT shimano anything-JIS)..symmetric. Only 2 are Campag and Phil these days, afaik.

[summilux]

Of course you are right about the retainer being aluminum. But it's really soft with shallow teeth and and contact depth that seems to shallow to me. I stripped one and that was a major PIA to get out. No such issue with PW. Yah I got the special tool. In fact I got two different ones. The loose one and the one integrated into the handle. I really like using them.

If you ever strip out a Campy BB here is the trick that the shop told me they used. This assumes you got one retainer off and the BB out. Take a quill stem and insert into the stripped retainer. Tighten the stem expander bolt so that the expanding stem snugs into the retainer. Turn.

I'll take your word for it. Wiggle.com listed a 111mm asymmetrical length in their specs.

Just checked Sutherlands, pages 3-39, 3-30, 3-31 and the 'track' BBs, 111mm, C-Record track cranks, is indeed symmetrical..Even the older BB for SuperRecord pista cranks were 109mm, but symmetrical.

[Ralph]

And I know a Record Triple I owned one time used the 111 asymmetrical BB. it's good to know I can use the superior Record 111 track BB in place of a Centaur 111. The Chorus/Record BB don't bind up with tq like the Centaur ones.....if the BB faces not perfectly parallel. Token's don't bind up either. The Record/Chorus BB's look like made by Token.

If you only ride dry go campagnolo

If any wet go PW

Too many square campagnolo toast once it rains

DO NOT use a Shimano compatible BB with a Campy crank.It ruins the tapers.
Phil seals are perfectly fine. I have never seen a Phil with bad seals.
Also, as mentioned elsewhere, the Stainless steel rings of a Phil BB are far superior to the soft aluminum cups Campy uses. Every shop I ever worked in has Phil tools. But since a Phil BB will likely last a lifetime, you won't need the tool.

Just to support this, folks on LFGSS have the Campy Pista cranks + Centaur 111mm BB pairing listed in their transmission database (https://www.lfgss.com/conversations/130300/).

And I've personally been running the same setup for 8 commuting years in SF.
