I'm obviously new to this forum. I have recently purchased and installed a cateye double wireless (speed and cadence) monitor. The problem I'm experiencing is when I am riding out of the saddle the speed drops very low. It doesn't go to zero, but it is considerably less than what I am actually going. Just wondered if anyone has experienced this before. The only thing I could think of is that maybe when I'm out of the saddle I am somehow blocking the signal.
