Details
Pro's Vibe Carbon Road Stem is stiff for maximum power transfer and control and light enough for any gram-counter. Its triangular shape and carbon/aluminum composite construction mean awesome steering control and power to the ground. And, it has a safe and secure 4-bolt clamp with titanium bolts for even more weight savings.
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.
Rise: +/- 10 degrees
Clamp diameter: 31.8mm
Steerer size: 1 1/8 inch (shim included for 1-inch steerers).
Weight: 115 grams
