I have an '07 Specialized S-Works Roubaix with an S-Works Carbon Crank that is based on the BB30 specification.

As I have 9,000 miles on the crank I have been planning to change out the 50/34 chainrings on the S-Works crank; but, I noticed the chainrings are out-of-stock at Specialized and the LBS doesn't stock them. The Specialized web site prices the chainrings at $200.

I see SRAM has a BB30 Red crank option. Does anyone know if I can make a direct change-out of the S-Works crank for the Red BB30 crank. For the differental in money I would like to tryout the SRAM Red crank.

I just installed new ceramic bearings in the BB from Enduro. I assume I can directly insert the SRAM Red BB30 directly in the new bearings.

All comments welcome.
