Need help with campy lockring

Hey, this is my first time posting here-

I'm building up a bike with various campy parts - i am mostly using the now defunct campy dayona but i am looking to get a 10 speed campy veloce cassette. I am planning on getting the 13-29t cassette.

My problem is that I do not know which lockring to get. I am looking at jensonusa.com and they sell several different sizes for campy lockrings.

I don't know what the "mm O.D" means. This is what they are selling:

Steel, For 12-16T, 26mm O.D.
Steel, For 12-16T, 27mm O.D.
Steel, For 12-16T, 29mm O.D.

It's for a Cramerotti frame. I don't have any specs for the frame. I just know that it was previously built with 10 speed campy dayona.

I would appreciate any help!

Go to www.Branfordbike.com and look up cassettes and lockrings for a very clear explaination. Centaur(Daytona) are the same. If you have a Daytona it would be 2001 or 2002. The Daytona is not "defunct" but, the name had to be changed to Centaur because of the name brand Daytona was owned by someone. There are 2 lock rings one for the small cog 11t and the other for 12t and 13t. They are 27mm but the outside diameter for the 12t or greater is 38.5mm and the 11t is 35mm. For the 13t you need a 27mm 9/10 spd with a 38.5mm lockring. The other diameters are for the older 8 or 9 spd cassettes. Branfordbike has a very good discussion of this.
The Miche lockring that is on Jensonusa is an equivalent lockring. Good luck.
