Origin8 Alloy Chainring

This chainring is designed for a 110mm 5-bolt mounting standard. Before purchasing, verify that your crankset uses this specific BCD (Bolt Circle Diameter) and bolt pattern to ensure a proper fit.

Yes, this chainring is engineered to be compatible with 8, 9, and 10-speed drivetrains. Its tooth profile and ramped design are optimized to work across these common multi-speed setups.

The ramps and pins are small machined features on the side of the teeth that help lift the chain from one ring to another during a shift. This design significantly improves shifting speed and smoothness, especially under load.

AL6061-T6 is a high-strength aluminum alloy commonly used in cycling components for its excellent balance of durability and weight. The CNC machining process ensures precise tolerances, while the anodized finish adds a layer of protection against corrosion and wear.

While it is technically possible, this chainring is specifically designed for multi-speed drivetrains with ramped and pinned teeth to assist shifting. For a dedicated single-speed setup, a chainring with a standard, non-ramped tooth profile is typically preferred to prevent chain drop.
