When stiffness and weight are the top on your list, you want Ritchey's SuperLogic C-260 Carbon Stem. This revolutionary design starts with a bar clamp that wraps a full 260-degrees around the handlebar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. Ritchey's first full-carbon stem, the C-260 features high-modulus carbon for stellar strength-to-weight ratio that translates into a solid but forgiving ride. And, the steer 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 with no problem.
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.
