BB for Campy Pista Cranks

Getting my fixie bike ready for some track riding and just bought Campy Pista cranks. Now I need some compatible BB for my English thread frame.

Any suggestions?

I believe 68x111 square taper is the right size so would something like this be compatible since it is listed as MTB bb? http://www.ebay.com/itm/Token-Bottom...ht_2432wt_1140

Even though this is a track bike, I'm moving this to mechanics (from Track) to get some good answers.

Yes they do. so the OP should be looking for a Campi Pista BB, which depending on the crank may be a bit obscure.


Jancouver can you post some pics of the crank? any idea what model it is? I believe the had SR/NR Pista cranks, then C-Record, and then just Record. and they would all have their own type of BB. the cranks up until about '93ish(?) may need a asymetrical spindle. I am not certain but I am no9t sure Campi ever made cartridge style Pista BBs.

Its brand new Campy Record Pista. Same as here: http://www.probikekit.com/us/compone...-chainset.html

My problem is the original Campy BB is sold out pretty much everywhere and if available they are asking some crazy amounts for it.

Campy uses a slightly different square taper (ISO) than Shimano and most other cranks (JIS). An ISO crank will not slide all the way up a JIS taper and will not be in the proper position or secure enough. You are right that the proper bb is expensive. Licktons in Chicago want $125 for it.

http://www.lickbike.com/productpage....B='0204-13'

Lickton's also has a 111 mm Centaur square taper bb for much less ($80) and the taper will be correct but I don't know if it will produce the correct chainline.

http://www.lickbike.com/productpage....B='0205-13'

You might try calling them and see if they know.

Campagnolo uses standard 2deg ISO taper on their spindles, but they have been made with a bewildering profusion of different designs. Cranks manufactured before the mid 80s typically will use an asymetrical spindle; newer models use a symetrical spindle. Record-level road spindles from the 70s through the 80s are designed to be used with the "thick" cups that have rifling to eject debris. Lower models and Pista models use more typical "thin" cups. And they were made for either 68mm or 70mm shells. Then throw in a few odd-balls like the "Con Sfere da 3/16" bottom brackets from the early 60s and the similar C-Record bottom brackets from the mid 80s and the CPSC changes from the mid 70s and you've got a real mess.

If your Pista crank is relatively modern, you might find that a modern Pista cartridge is the easiest solution. If it's an older model, look for a matching Pista bottom bracket or be prepared to experiment with different cup and spindle combinations (and you don't have to limit yourself to Campagnolo parts) to find something that works.

campy shows that the pista bb is asymmetric, like the chorus triple 111mm.

This is tough one because I would normally recomend a Phil but they only have a 110.5 and I am not sure that will be long enough

If the phill is asymmetric then it should work just fine.

Phil axles can be moved sideways in the bearings to make them Symmetrical.
their press fit is just that..

'In stock' means they have to be guessing, in advance, your needs ..
and have millions of dollars tied up in inventory..

more realistic is to say, what you want
and then they order it from their Wholesalers.. it should only take a week.

True both JIS and ISO use the same 2 taper per side (4 included angle) but the taper lengths and width across the flats at the spindle ends are enough different to often cause interchange problems. Here is Sheldon Brown's description of the differences:

"ISO square taper spindles run longer, and taper down to a smaller end than J.I.S. spindles do.....J.I.S. spindles are shorter and blunter, they don't taper down to quite as small a square.....
If you install an ISO crank on a J.I.S. spindle, it will sit about 4.5 mm farther out than it would on an ISO spindle of the same length. Confersely, if you install a J.I.S. crank on an ISO spindle, it will wind up about 4.5 mm farther in than it would on a J.I.S spindle of the same length. Theoretically, ISO cranks should only be used on ISO spindles, and J.I.S. cranks only on J.I.S. spindles.In practice, you can very often get away with mixing these sizes, as long as you select a spindle length that gives the desired chainline."

In the OP's case, the chainline is important and the right spindle length and taper is necessary.

To answer your question, I would say yes, this BB will work. It's Campy/ISO taper and the right size spindle 111. I have not idea why they are saying it's for a MTB triple, Campy MTB components (that were fazed out in the 90's) had spindles @ 124mm and 132mm Further, since it is for a road triple, it's going to be asymmetrical. Otherwise, either of the current Veloce or Centaur 111mm square taper BB will work.

That's not strictly true. Record and Chorus square taper road bottom brackets were indeed asymetrical. Centaur and below were symetrical.
