Standard size stems are designed to fit bars with a clamp diameter of 25.4mm for MTB's and 25.8/26.0mm for Road Bikes. Oversized stems are designed to fit bars with an oversize 31.8mm clamp diameter.
The OS-99 CSI stem combines the strengths of both aluminium and carbon fibre resulting in a stiffer stem that has improved vibration damping properties. Performing as a composite material in its own right the OS-99 CSI stem benefits from a dramaitic reduction of typical fatigue phenomenon such as Stress Corrosion Cracking and Creep Propagation Cracking giving the stem unpresidented longevity.
Features:
3D forged, CNC machined from AL7050 and crabon wrapped
