PBR Twin Color Aluminium Ultra-Light Self-Cleaning Hard Anodized 702 - 520 SprocketRef : PBR01031A / 1096612002

PBR Twin Color 702 Sprocket - 49 Teeth (520) — a machined cross sprocket for demanding riders seeking lightweight and reliability. Made from 7075 T6 aluminum, it combines strength and low inertia to keep the rear end responsive during starts and accelerations.

• Material: 7075 T6 aluminum, high-precision machined.
• Number of teeth: 49 (520 pitch), standard type.
• Optimized tooth profile to facilitate mud evacuation and limit efficiency loss due to chain/sprocket friction.
• Hard anodized Twin Color — blue finish, enhances surface durability while maintaining aesthetics.
• Strategic cutouts to lighten the part without sacrificing structural strength.

In muddy MX, SX, or enduro terrains, this sprocket performs cleaner thanks to its anti-mud profile. Its lightweight design reduces rear inertia, helping the chain transmit power more efficiently and making the bike more responsive during acceleration. The hard anodization protects the surface against superficial wear and contributes to the longevity of the part.

Suitable for 520 setups and compatible with many cross/enduro machines — examples: SHERCO 450 SEF‑R FACTORY (2022), BETA RR 390 4T (2020), GAS GAS EC 250 F (2015).
