Designed for Shimano XTR M9100, XT M8100, SLX M7100, and Deore M6100 cranksets, this direct-mount chainring is fully optimized for Shimano Hyperglide+ 12-speed chains (CN-M9100, 8100, 7100, 6100).
The patented oval profile enhances traction, climbing ability, and pedaling smoothness, while reducing knee strain. Each ring undergoes a PVD Rainbow Titanium coating process, delivering outstanding durability and a completely unique finish — no two chainrings look the same.
