PBR Standard Steel Sprocket 600M - 420 (Manufacturer part number: 600M 14 18NC): a transmission sprocket designed from the experience gained in competition by PBR. Designed for urban riders and lightweight roadsters, it integrates into drivetrains equipped with a 420 pitch chain and features 14 teeth for standard gearing.

• Material: 18NCD5 alloy steel, treated for mechanical performance suited to transmission stresses.
• Number of teeth: 14 — 600M sprocket version, standard mounting.
• Compatibility: 420 chain, intended for urban applications and roadster/small displacement riders.
• Manufacturing quality: strict process ensuring consistent tooth finish and reduced friction at the chain/sprocket contact.

This sprocket is aimed at riders looking for a robust OEM replacement part to limit premature wear of the transmission. The 18NCD5 alloy provides good resistance to corrosion and abrasion while maintaining the geometry necessary for smooth chain engagement. By changing the sprocket, you restore a gearing behavior that complies with manufacturer specifications and facilitate the maintenance of your rear end.
