BioCentric 30 – Black
The BioCentric 30 has a similar design and function as the BioCentric II but is designed for use in most PF30 shells. The sealed bottom bracket is integrated into the cups of the BioCentric 30 and is compatible with most 24mm spindle cranks. And if you run GXP cranks, a reducer is provided to ensure compatibility.
