PBR Standard Steel Sprocket 2311 - 520 (Manufacturer Ref: 2311 15 18NC)
Designed for off-road practices, this PBR steel sprocket offers a robust replacement part suitable for Cross applications. Its standard steel design ensures wear resistance adapted to the demands of a 520 chain, providing reliable transmission both on trails and in competition.
The choice of a 15-tooth sprocket directly affects the final transmission ratio; it replaces the original sprocket to restore engine behaviour consistent with Cross use. Its steel finish prioritises durability against the demands of muddy or stony terrain.
Before installation, check the condition of the chain and the crown to ensure optimal operation. PBR offers a simple and reliable solution to replace your original sprocket on Cross machines equipped with 520.
