Specialized's Aerostem is designed to be used with the Specialized Carbon Aerobar (sold separately). It's adjustable for 80mm or 110mm reach.
Stem angle is one of the factors that determines handlebar height. A listed angle of 0 degrees actually provides a rise of 16-20 degrees, depending on the bike's head-tube angle. Flexible, athletic riders prefer lower-rise stems, while recreational riders usually favor higher-rise stems.
