Ritchey's WCS C260 stem starts with a bar clamp that wraps a full 260 degrees around the handlebar to distribute clamping stress more evenly through the handlebar, faceplate, hardware, and stem body. The steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube. The body is 3D-forged from an advanced 7050 aluminum and internally machined for further weight reduction. Premium quality chromoly steel bolts are used throughout, but in a smaller T-20 Torx size that shaves a few more grams with no sacrifice in strength or rigidity.
- Stack Height: 42mm

Stem angle is one of the factors that determines handlebar height. A listed angle of 0 degrees actually provides a rise that is dependent on your bike’s head angle (see image).
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 135mm, it actually extends 108mm parallel to the ground.
