Bontrager quality and innovation come together in the Race Road Stem. Precision cold-forged 6061-T6 aluminum makes it light and stiff, and the opposing two-bolt steerer clamp keeps it secure. Plus, the CNC-machined 2-bolt faceplate offers a great grip, displays the classic Bontrager logo and makes installation a snap.

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.
