Dura-Ace Chainring Sizes

[rockdude]

Trying to convert my Standard 130mm DA cranks into a cyclocross crankset.
I know I can't get to compact size like 44/34 but how low can I go. Is there a way to get 46/36?

I think 38t is the smallest you can go on 130 bcd. You're going to need 110 bcd cranks.

If you have 7800 you need this http://www.amazon.com/Shimano-FC-7800-10-Speed-Cyclocross-Chainring/dp/B0039V028M

Awesome.

So it looks like 46/38 is the smallest I can go for a DA 130mm. I better stock up in the 13-29 cassettes...
