Extralite OctaOne Narrow-Wide Chainring

With the OctaOne Extralite takes their CNC skills and experience with lightweight chainrings to the 1 x 12 & 1 x 11 (or 1 x 10, 1 x 9) market. With every other tooth being thicker the chain is promised to stay tight through the roughest of terrain. This shape is achieved by starting with a 7075-T6 sheet and machining the chainring with chainring threads to keep weight down. Once machined the chainring is hard anodized to increase durability and lifespan.
