Bontrager Race Lite OS Stem (+/-7-degree rise)
Details
Bontrager's Race Lite OS 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 CNC-machined 2-bolt faceplate is ultra tough and makes handlebar changes a breeze, too.
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.
The Race Lite OS can be used as a -7-degree-rise stem or flipped to yield a +7-degree rise.
This stem has a 31.8mm handlebar clamp and a 1 1/8-inch steerer clamp.
