Product Description:
This Stone 96BCD asymmetric oval chainring is designed for Shimano 4-bolt MTB cranksets with asymmetric 96BCD mounting. Made from high-strength 7075-T651 aluminum alloy and precisely CNC-machined, it offers excellent stiffness, durability, and reliable chain retention for 1x drivetrain setups.
The oval shape helps improve pedaling efficiency by optimizing power output through the pedal stroke, making climbing and acceleration smoother. The narrow-wide tooth profile improves chain grip, reduces chain drop, enhances mud-shedding performance, and helps lower drivetrain noise during off-road riding.
