odd one this!

had an odd noise coming from my bike like rubbing noises, figured the cable for front mech was catching crank arm which it was, but also noticed a ticking noise.

couldnt work out what it was then realised that it happened every time the magnet went past the sensor - and coincided with the little green light. magnet isnt anywhere near the sensor so does it tick to register the rev?

    There is a very light tick when the magnet passes the sensor!

    Yeah, it is very quiet though, dont think you would hear it on the bike, if you do check the magnet isn't clipping the sensor

    some sensors use a reed switch, these make a slight tick as they close/open each time the magnet passes

    I had the exact same thing happen last night on a ride.
    All it was in the end was the sensor had moved a fraction and was clipping the magnet, easy fix.
