PBR Steel C45 Standard Sprocket 4431 - 420 (Manufacturer Ref: 4431 44 F)
Designed by PBR, a brand born from competition, this rear sprocket made of C45 steel is aimed at urban riders looking for a robust and reliable part for their transmission. Black and crafted for a 420 chain pitch, it features 44 teeth and a standard profile suitable for original replacements.
The manufacturing processes used by PBR and the selection of quality raw materials aim to provide good resistance to corrosion and abrasion while minimizing friction at the chain. Ideal for daily urban use, this sprocket is particularly suitable for mopeds and small displacement bikes equipped with a 420 setup.
Examples of compatible models: RIEJU RRX SPIKE 50 (2009), RIEJU RRX 50 (2008), RIEJU RS1 50 (2002). Before installation, check the chain pitch, number of teeth, and the hub spacing to ensure proper fit.
