"In the case of its new Matrix carbonalloy construction, high-modulus carbon fiber is said to play an actual structural, not just cosmetic, role to the underlying 3D-forged aluminum base. Ritchey claims this process produces a stem that is both lighter and stronger than one that uses either material exclusively since the two are fused together.
"True to its billing, our 110mm long test sample is light, weighing just 121g with titanium hardware... Ritchey also graces the stem with its signature paired-four-bolt faceplate and bias cut steerer clamp to reduce the risk of damage due to overtightening. Lengths ranging from 90-130mm are available, all with a flip-flop 6° angle."
