Here's an exchange I had with a "knowledgeable" seller.

Questions from other buyers for this listing *

Q: *Hi, I'm the guy who answered your question regarding the BCD. Can you provide for me the name and number of the bike shop that gave you the incorrect information? Thanks!
Answered on Feb-23-05

** A: *Sorry for not providing the information about the BCD sooner. Thanks for your patience, the correct BCD is 130. Please email with any more questions, again, thanks for your patience.

Q: *BCD : bolt circle diameter, measurement (metric) between opposing bolts that fasten the sprocket to the drive crank arm...I hope this helps.
Answered on Feb-23-05

** A: *I talked to a bike shop and they explained to me that the BCD on this crank is called a square taper. E-mail if this does not answer your question.

Q: *Do you the BCD? Is it for a double or triple?
Answered on Feb-22-05

** A: *I know it is for a double but am not sure if it is compatible with a triple. I don't know what BCD means, sorry.
