SUNSTAR 5-130840 Works Triplestar 40T Aluminum Rear Sprocket 520 Pitch 

• Aerospace-Grade Construction: Made from the highest quality 7075 T-6 aluminum, which is an aerospace-grade material known for its high strength-to-weight ratio.
• Lightweight Design: Features computer-designed weight reduction holes to minimize unsprung weight and enhance stability without compromising strength.
• Superior Power Transfer: The exclusive tooth-valley design provides up to 24% more chain contact area compared to other sprockets, ensuring better power transfer to the rear wheel and distributing impact stress more effectively.
