PBR C45T Steel Sprocket 4320M - 520, 39 Teeth

Designed for demanding roadsters and sports bikes, this PBR sprocket made of C45T steel combines CNC machining and high-quality heat treatment. The tooth area undergoes hardening followed by induction tempering, an industrial process that strengthens the wear surface and preserves durability over time. The result: a sleek and robust monobloc piece, designed to withstand the stresses of chain/sprocket transmission over long distances.
