Salsa's Pro Moto Stem securely holds your bars while offering great control. Stiff forged and welded aluminum construction with a wide clamping area cut down on flex. Plus, for extra security, Salsa's Stiff Upper Lip technology utilizes an interlocking groove to remove torsional loads from the clamp bolts.
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.
