Thomson Black 90 deg 28.6 Bicycle Stems

About Thomson - Thomson is leading with innovative design for two primary markets - aerospace and cycling.

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

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.

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