|What options do I have to save some weight? Can I go with a higher end Campy BB or do I have to go aftermarket?|

|Daytona (centaur) / chorus / record are interchangeable throughout the set. The material used in the construction is different.
Save weight? Realize the difference between Centaur and record bottom brackets is 3.45 ounces. Just needed to put it into perspective.
Differences: (assuming all doubles, not triple)
Centaur: 288g;hollow axle, light alloy cups
Chorus: 220g; light alloy cartridge and cups
Record: 190g; oversize hollow axle; composite/light alloy cartridge; light alloy cups
NOTE: Daytona and Centaur are the same. Daytona Beach, FL forced Campy to change the name as the town had registered the trademark. I guess it would have looked bad for NASCAR andthe town if a Daytona equipted bike passed Bobby Allison on the back stretch.

|The Daytona(Centaur) BB cannot necessarily be upgraded to Chorus or Record. If you have Daytona cranks they require a 111mm BB spindle. Chorus and up use a 102mm bracket. You could upgrade cranks too but that's getting a bit expensive. I doubt saving 68grams of BB weight is going to turn you into Lance|

|It's true that centaur and chorus/record aren't interchangeable. The best replacement is phil wood. Steel/alum. is about 40 gms. lighter than ac-h centaur; and titanium is a little lighter than record, including the mounting rings.|

|I was taking it from memory from when I compared and ultimately decided on chorus groupo. I looked it up and you're right, the Centuar does have the larger 111mm spindle where the chorus and record have the 102mm.|| |
