Left crank dropping


I've had my Infocrank for about 3 months now.

My left crank intermittently loses power for 5 minutes every couple of hundred kilometers or so. 

Shown in the image attached.

The batteries are the original, done 125 hours.

Any idea whats causing this?


Hey Travis,

Thanks for creating a forum for this issue. Can you send me a .FIT file displaying the drop out to so we can have look? 

Hope to hear from you soon.



Thanks Aaron,

FIT files emailed as requested.
