|Today while climbing standing up I notices a sound that could come from the magnet toughing the sensor. These are 5mm apart as recommended. While the lateral movement of the wheel is controlled by the break pads, could the spokes flex that much?. The danger is that the sensor is caught in the spokes break off, or cause spokes to break off sending the rider on is nose. Any one with this experience. I use a hand built Campy Montreal rims 36 spokes dubble butted 2X.

|First of all, make sure that the pick up is mounted in FRONT of the fork. That way, if the magnet were to hit the pickup for any reason, the wheel rotation will cause the pick up to rotate away from the wheel rather than jam into the spokes.
Second, I wouldn't worry too much if you really do have 5mm of clearance. I'ce noticed that bike computers normally make a very faint sound when the magnet induces a voltage in the pickup.

|I have a wireless flightdeck and was wondering if there was any point to moving the sensor to the back?

|Cateye mounting instruction says 45cm max between sender and reciever.
|Yup - works on mag trainer then. nm||muncher|

|Actually the sound is caused by the reed switch closing inside of the sensor. The reed is a flat spring that is normally in the open position and is attracted to the magnet as it flys by. There is a voltage on one of the wires to the sensor and the reed switch closes the circuit and the pulse is then counted by the computer. The sound of the Cateye reed switch closing is usually a faint "ping".|

|I've encountered the same exact thing. I also have the Cateye Cordless. |
I am not sure of the possiblity of this, but perhaps our forks are flexing?
I have a Giant TCR2 with the bladed carbon aero fork.
