This offering is for a new-old-stock Campagnolo cartridge (sealed) bottom bracket (Model AC-S). Some of it's specifications include the following:
Cup type/size: English threaded...1.37" cups x 24 threads per inch (tpi)
Shell width: 68 mm
Spindle/axle type: ISO square-tapered
Spindle/axle length: 115.5 mm (generally considered for select triple chainring cranksets...refer to the discussion that follows for more details)
Production locale: Made in Italy
This is a good quality Campagnolo bottom bracket that includes alloy cups and a solid spindle. Catalog research indicates a production window from 2000 to 2005 and the intended factory match was primarily the Veloce crankset...although our Campagnolo catalogs also identify the Daytona crankset (from 2000 to 2001) and the Centaur crankset, which succeeded the Daytona crankset (from 2002 to 2005), as alternative factory crankset matches. We should also note the right crankarm profile for the Mirage crankset from this same era was similar, so this bottom bracket will also promote a good chainline with this lower-end Campagnolo crankset offering from the same era. There may be other compatibility options as well, but we would have to research those on an individual basis.
We should make a few additional observations regarding the spindle length of this particular bottom bracket and the impact it will have on a functional chainline. More specifically, there may be some circumstances where the 115.5 mm spindle length is too long for any of the triple cranksets noted above. This circumstance comes about when a front derailleur is mounted on the old standard (28.6 mm) seat tube. This scenario results in a front derailleur cage positioned closer to the frame relative to an oversized (31.8 mm and 34.9 mm) seat tube. As a result, a frame with an old standard seat tube requires a shorter bottom bracket spindle length to bring the chainrings closer to the frame to better match the position of the front derailleur cage.
For this reason, if mounting one of the above triple cranksets on a frame with an old standard seat tube, then a better Campagnolo bottom bracket option is our equivalent offering with the slightly shorter spindle length of 111 mm. A final comment here is that regardless of the seat tube diameter measurement, one of the above Campagnolo cranksets in a double chainring model will always require the shorter (111 mm) spindle length to ensure a functional chainline.
As for condition, our small lot of these bottom brackets are new and still retail boxed (with all related Campy reference materials on specs., installation, etc.), as pictured to the left (although some of the boxes are shopworn).

Note to international customers regarding shipping...
We apologize to those that feel some of our international shipping charges are too high. We only charge actual shipping rates, but once an order exceeds a certain amount, we hesitate to use the least expensive US Postal Services First Class International service. We feel this way, because this service is not trackable or insurable...so more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at USPS.com and insurable...so less risk of loss. Unfortunately, this service is more expensive, especially for smaller/lighter packages, relative to the First Class International service. We are sorry about these higher shipping costs, but hopefully our notes help to explain why this is the case.
Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we apologize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
