A: Yes, it is constructed from enhanced 7075-T6 aluminum that is 33% lighter than steel to minimize unsprung mass.

Q: How does the specialized tooth profile benefit drivetrain longevity?
A: The tooth layout is engineered to let the chain roll smoothly on and off the teeth, reducing friction, noise, and wear over time.

Expert Pro-Tip: Always inspect your drive chain and front sprocket when installing a new rear sprocket. Pairing a fresh aluminum rear sprocket with a worn, stretched chain will accelerate wear and significantly shorten component life.
