PBR Standard Steel Sprocket 2142 - 525 (Manufacturer's Ref: 2142 14 18NC)
Designed by PBR, drawing on its competitive heritage, this 14-tooth sprocket is machined from high-quality 18NCD5 steel alloy. Its "standard" design caters to riders who prioritize reliability and longevity for their machine's secondary transmission.
The choice of 18NCD5 steel offers excellent resistance to corrosion and abrasion while reducing friction between the chain and the sprocket. Ideal for sustained road use, it easily integrates during a wear replacement or a gearing change. Precise mounting and alignment are recommended to preserve the lifespan of the chain and the crown.
