I bought the new speed and cadence sensor for my bicycle and mounted it.
I use it with my 910XT.
What I found is that the cadence sensor needs some turns of the crank to get activated
whereas the speedsensor does not need.
And the cadence sensor quickly fall asleep. So after few secods I do not turn the crank
it does not send any information (display is "_ _").
Most times this is obvious when going downhill.
Is this normal behaviour?
How to fix that?
