North Shore Billet 104 BCD Narrow Wide Chainring
By utilising a standard chainring profile and varying the tooth thickness, these rings help retain the chain through rough terrain and high speed pedalling.The combination of the narrow / wide teeth virtually eliminate dropped chains and the thicker tooth also helps with better chain engagement and provides increased forward drive through improved chain contact.
All North Shore Billet chainrings are machined from aerospace grade alloy. This superior grade of alloy ensures the rings are light, strong and durable.
In addition North Shore Billet use a hard anodising process. This provides a tough and durable finish that further improves chainring life.
The 104BCD rings will fit any brand crank with a standard 64/104 BCD.
Compatible with all 10 and 11 speed chains and all external bottom brackets including BB30 and GXP
We recommend using a 10 speed chain if running a 1x9 setup for better chain retention and improved rear shifting.
Narrow / wide tooth profile for ultimate chain engagement, retention and mud clearing
CNC machined from 7075 T6 aerospace grade alloy for strength and precision
Hard black anodising ensures a smoother quieter drivetrain and improves chainring life
