Details

At just 103 grams, Ritchey's C-260 is among the lightest stems in the world. This revolutionary design starts with a handlebar clamp that wraps a full 260 degrees around the bar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. The steerer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube. So you can run carbon bars and a carbon steerer no problem. Weight and stiffness were prime considerations; the C-260 is 3D forged from 7050 aluminum and machined, even the steel M4 bolts shave a few grams with no sacrifice in strength or rigidity.

Stem angle and length measurement

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.
