Cateye Mity 8 Computer
Recently purchased this computer. For the life of me I cannot figure out
how far down the fork to put the sensor. When I mounted my last computer it was clearly outlined in the directions. Have looked online but to no avail. Anyone use this computer? Thanks |

Themagnetically induced spike's amplitude is related to, among other things, velocity. If mounted too close to the hub, the sensor may miss pulses at low speeds. About halfway out should be fine. |

Except the Cateye's sensor is a simple magnetic reed switch; there is no "induced spike", just a contact closure that will not be significantly dependent on the speed of the passing magnet. (The only computers I am aware of that do depend on induced signals are the Avocets, and they use a 20-pole magnet ring mounted at the hub.) Responding to the original poster, if there is no limitation to where you have to put the wheel magnet (IIRC some Cateyes had a magnet carrier which wrapped around two spokes, so the magnet and sensor had to go about mid-wheel), I'd put it as close to the hub as you can get it, mostly because that lets you tuck the sensor in back of the fork blade instead of having it stick out toward the spokes. |

Responding to the original poster, if there is no limitation to where you have to put the wheel magnet The OP asked how far down to mount the sensor. The answer is just far enough down to align with the magnet. Mounting higher than the point at which the rim passes betwen the forks will unnecessarily complicate mounting the magnet, as will mounting below the o/s diameter of the hub flange best wishes james |

I've always been told to mount it as close to the hub as possible. The
reasoning behind this is that the closer the magnet is to the center, the slower it will turn. With the magnet mounted closer to the rim this could cause erratic readings at higher speeds since the magnet passes the sensor much faster. I haven't experimented with this but it does make sense.
