I have an e*thirteen crank and would like to use a power meter. What are my options? 

Answer: It depends which crank you have and what type of power meter you are using. See below. 

While e*thirteen does not offer a power meter crank currently, you can use pedal based power meters with our cranks such as those made by Garmin or Favaro. 

Crank spider based power meter compatibility should be confirmed with the power meter manufacture. Our cranks use a proprietary spider interface and therefore the manufacture would need to offer spider mount specifically for the e*thirteen interface. It should be noted that the spider interface on Helix cranks is 4mm thick whereas our previous generations of cranks were 5mm thick. This means it is possible that a power meter which works on an XCX, TRS or LG1 crank will not be compatible with a Helix crank.
