Is campy daytona crank compatible w/Chorus bb?Dang

Hi folks,

is campy daytona 9spd cranks compatible with Chorus or Record bottom bracket?

This is my problem: I am moving from a bike that has English-threaded bottom bracket to a bike that has Italian threaded bb. I am moving all my old components to the new bike . My current bb isn't compatible so I am planning on ordering Italian threaded bb but don't know wether it would be compatible with my existing Daytona crankset.

thanks for your input.

Order an AC-H bottom bracket. You need to specify the proper spindle length as this bb comes in 111mm and 115mm spindle lengths. 111mm is appropriate for bikes with a 28.6mm diameter seat tube -- i.e.: steel frames. Use the 115mm spindle length on bikes with 32mm or 35mm seat tubes. The QBP catalog says to use the 115mm spindle with triple cranks, but I'm using a 111mm with my racing triple and it works well. Colorado Cyclist has this part in Italian threading in both spindle lengths: $20.

Daytona is a 111mm, Chorus is 102mm. Campag website is actually quite helpful on this. I have a Daytona chainset and didn't like the BB as it looks cheap and weighs 300g. It appears however that you can use any of the ubiquitous Shimano compatible 110mm ones without any problem. I picked up an FSA Titanium very cheaply which weighs 175g and works perfectly

The angle of the taper is the same, but Shimano's taper is slightly larger than Campy's. You will not be able to draw the Campy cranks far enough onto the spindle, and you could damage the crank arm by trying to force the crank on the spindle.
