Jon,

Could I suggest returning the crankset and simply buying new chain rings for the crankset you had originally? While chain rings are not always cheap, in the end it is the easiest way to go because you keep the same FD and BB. There are many places to order them but I like Loose Screws. It is truly a "Mom and Pop" online shop and I've had great customer service with Jean.

I'd guess that you have 130 BCD chain rings but they could be 110 BCD. If you can measure the distance in mm between two of the five bolts holding the chain ring to the crankset arm, and post that measurement, we'll calculate the BCD for you and help you with what to buy.

Here is a list of the 130s: http://www.loosescrews.com/index.cgi...d=399475416012

And here are the 110s: http://www.loosescrews.com/index.cgi...d=399475416012

Great looking bike! Welcome to C&V. Do you have a closeup picture of the existing crankset?
