Thanks to the adjustable shim that sits between the stem and fork, Felt's VA Alloy Adjustable Stem is adjustable from +/- 5 degrees to +/- 15 degrees for a perfect fit on your road or mountain bike and optimum ergonomics. Forged and CNC'd from 6061 aluminum for excellent lightness and strength, the VA also boasts a 4-bolt clamp that's compatible with carbon and aluminum handlebars.
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.
