We define color as the main color of the item. It may have accents or highlights in other colors.

These models are available for online purchasing and can be shipped directly to you.

Bar clamp diameter is the diamater of the handlebar.

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.
