Will Changing Chain Rings Effect Power Meter Accuracy?

All current generation power meters feature OmniCal, allowing you to swap chainrings without affecting accuracy. Simply torque the chain ring bolts to the manufacturers specification and be sure to set the power meter Zero Offset before every ride. Nothing further is needed. 

*Exceptions*

If you're unsure which power meter model you have, please contact Quarq Customer Service.  When contacting customer service, please provide the power meter ID located on the power meter spider. The ID consists of 3 letters and 5 numbers such as; ABC12345 or 12345ABC.
