Ritchey 96- deg 70 mm Bicycle Stems
About Ritchey - "Ritchey bicycle components have been raced to victory in some of the biggest cycling competitions in the world including the UCI World Championships, the Tour de France and the Olympics and it all began in a simple garage in Menlo Park, California with Tom Ritchey.'
Stem angles are measured perpendicular to the clamp. For example, a 90 degree stem is straight. Sometimes, this may also be refered to as a 0 degree stem. If two measurements are listed, the stem can be flipped for angling up or down.
Stem length is measured from the center of one clamp to the center of the other clamp. This measurement is sometimes known as the reach or extension.
