Details
Profile’s Aris OS stem is a no-nonsense stem made from 6061-aluminum that’s been shot peened and anodized for strength and durability. The 4-bolt faceplate is stiff, ultra tough and makes handlebar changes a breeze. And, the opposing-bolt steerer clamp is safe and secure.
See how stem angle and length are measured.
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.
Stem length is measured along the side of the stem from the center of the steerer to the center of the handlebar clamp (see diagram). Keep in mind that as a stem provides more rise, its effective length decreases. In the example above, if the +17-degree stem measures 135 mm, it actually extends 108 mm parallel to the ground.
