POWER METER: Which chainrings are compatible with the Gen2 power meter spider?

The chainring must match the spider’s BCD, bolt pattern (4-bolt or 5-bolt), bolt-hole layout, crank interface, chainline, and drivetrain speed. Matching the BCD alone does not guarantee compatibility.

For example:

If the power meter is 110 BCD, select a 110 BCD chainring;
If the power meter is 107 BCD, select a 107 BCD chainring, and so on.

Before purchasing, check the compatibility chart and select the correct chainring SKU for your power meter spider and drivetrain.
