rear sprocket

Do the CA77 and CB77 rear sprockets have the same bolt pattern? I have found the 520 aluminum rear sprocket I have been looking for on sprocket specialists web site, but it listed for a CA77. They also have rears in 530 in an incredible number of sizes for CB77s. Thanks in advance!

I don't know if the bolt pattern is the same, but you should call those folks and ask, they are very helpful. I have sent them an original sprocket to copy in a different size, and the price was not much higher than for a stock pattern. --Randall
