Details

Bontrager's Race Lite Stem is a reliable race-ready tiller worthy of the finest road and mountain machines. Thanks to its one-piece, cold-forged 6061-T6 aluminum construction, it's strong, light and stiff. The 4-bolt faceplate is ultra tough and evenly distributes clamping forces your bars. And, the angled, opposing-bolt steerer clamp is safe, secure and compatible with carbon steerers.

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.

    I got this stem on a new '13 mamba. The stem is very weak and will not hold the headset stack in place. After an initial ride of 12 miles there was a significant amount of play in the headset. After the LBS tightened a second ride produced the same results. I am looking now to replace this instead of going back and forth with the LBS.
