Choose your seal/Lube options. Heavy weather or pure race seal and light lube. Bearings and housings are the same but lube and seal is optional. If you want more life from your road bearing choose the AC option.

R= Road

AC= ATB & Cross or wet road riding.

C-Bear clarifies different OSBBs:
Road Carbon Virgin = 61x46 mm (non-standard PF30)
Road Carbon Virgin + expoxied aluminium insert = BB30 = 68x42 mm
Road Aluminium = BB30 = 68x42 mm
MTB = PF30 = 73x46 mm
Therefore, first determine whether your Specialized road bike is carbon or aluminium frame?
Then, is it with a virgin carbon bb shell OR with an aluminium insert already expoxied by the manufacturer in the virgin carbon shell.
Best is to measure the length and the inside diameter of the bottom bracket shell of your Specialized bike. Or check with Specialized or with the bikeshop you purchased your bike from.

Owners of Specialized road frame with a virgin carbon shell, just remove the Specialized delrin cups and install C-Bear OSBB 61 bottom bracket, depending on the crank of your choice.
If you have a Specialized with the insert already expoxied, you can elect C-Bear BB30 bottom bracket, depending on the crank of your choice.

C-Bear is the first in 2012/3 that came out with the silencing OSBB61 for Campagnolo cranks. Some even tried to custom make a solution and still did not get the results matching C-Bear durable no creak bottom brackets. Watch installation video C-Bear OSBB61 - Campa
