New Phased teeth pattern, better chain retain.
Phased machined teeth guide the chain more consistently.
Long lasting hard-anodizing: all rings are firstly cnc'ed from Ergal 7075T6 billet sheet then black hard-anodized.
The chainline of the OctaPhase2 offers 1mm more internal line than the outer ring of usual 2x setups.
Additionally it can be mounted reversed on the inner side of the spider to reduce the chainline by 7mm.
Lightweight performance chainrings for 1x12/13 (and 1x10/11 setups too).
Unmatched weight to performance ratio!
