STONE 96BCD Asymmetric Oval Narrow-Wide Chainring for Shimano Deore, SLX, XT & XTR 1x MTB Cranksets (32T–48T)
Product Description
This Stone 96BCD asymmetric oval chainring is designed for Shimano 4-bolt MTB cranksets with asymmetric 96BCD mounting. Precision CNC-machined from high-strength 7075-T651 aluminum alloy, it combines stiffness, durability, and dependable chain retention for 1x drivetrain setups.
The oval shape optimizes power delivery through the pedal stroke, improving pedaling efficiency so climbing and acceleration feel smoother. A narrow-wide tooth profile grips the chain more securely, reduces chain drop, sheds mud effectively, and helps keep drivetrain noise down on off-road rides.
