Add Ritchey's Pro Road Stem to your road rocket for superior control and handling. It's made of forged aluminum for light weight and excellent durability and stiffness. And, it features Ritchey's Bias Clamp and a 4-bolt faceplate, which make it super safe and secure.
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.
