Easton EA70 OS Aluminum MTB Stem (Plus/Minus 6-degree reversible-rise)
Details
Easton's EA70 Aluminum MTB Stem is a great upgrade. Easton Taperwall-aluminum technology and a shot-peened finish provide a great balance of light weight, high strength and stiffness for excellent steering control in all conditions, and outstanding durability. Plus, the carbon-handlebar-compatible 2-bolt clamp has replaceable hardware so stripped bolts will never be a problem again.
Stem angle is one of the factors that determines handlebar height. A listed angle of 0 degrees actually provides a rise of 16-20 degrees, depending on the bike's head-tube angle. Flexible, athletic riders prefer lower-rise stems, while recreational riders usually favor higher-rise stems.
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.
Steerer Size: 1 1/8 inch
