That is correct about the sensors. Sampling rate is 1sec as per the Garmin head unit. I know guys that are going sub 11s and they only have a basic speed sensor and a friend with a stopwatch. Don't for a second think that speed is tied to a sensor or head unit or power meter

Can't buy Bontrager stuff from OS either. In the end it was a bonus as I got both sensors with shipping for only $10 more than one of the Bontrager sensors
