Ultra durable and no dropped chains

CNC'd from a sheet 7075T6 with meticulous detailing and ultimate weight reduction. Compatible with 11, 10 and 9speed chains the OctaOne has a specially machined tooth profile that keeps the chain on and for even smoother mating to the chain with the thick-thin profile. 8mm and 6mm billet construction improves stiffness and optimises chainline. Each tooth has been angled to allow solid engagement when in the 42t or 11t position and will equally handle a 11-36t range found on the 10speed cassettes.

4 chainring bolts have been cut into the chainring themselves allow for further weight reduction and a stiffer interface with the crankset. Chainring is finished with a special hard coat anodising for long term durability and all graphics are laser etched. It will fit cranksets with a 4-bolt 104BCD spider or crank arms.
