WTB

"WTB was founded in Marin County, California in 1982, fueled by the need to create durable and reliable mountain bike-specific equipment. Back then mountain biking was a new and burgeoning sport, and mountain bikes weren't much more than cobbled-together oddities. The original WTB crew was captivated by the experience of riding bikes on dirt trails, and they started creating more durable and functional components for their own bikes. Soon, local frame builders sought to outfit their bikes with WTB's high-end components. WTB was able to turn our passion for bikes into a successful business."

Stem length is measured from the center of one clamp to the center of the other clamp. This measurement is sometimes known as the reach or extension.

S.H.I.S clamp diameter is the steerer tube diameter.

Stem angles are measured perpendicular to the clamp. For example, a 90 degree stem is straight. Sometimes, this may also be refered to as a 0 degree stem. If two measurements are listed, the stem can be flipped for angling up or down.
