Seven Aluminum Stem

Our high-strength 7075-T6 aluminum stems feature a 4-bolt removable faceplate with a reverse bolt design. The steerer end employs a bias-cut and opposed clamp bolts to reduce clamping loads. Just 131g for an 11.0cm, these lightweight stems are available with a 31.8mm clamp diameter in 84° or 96° angle. Choosing the Ti bolt upgrade lightens the stem to an incredible 116g.
