    bike computers?

    where is the best position to place the magnetic trigger for your bike computer? very close to the centre or in the middle or closer to the outer rim?

    Also, i have found that no matter where i place magnetic trigger on the spoke it creates an im-balance when the wheel is spinning. This is evident when you prop the bike upright on the rear wheel so that the front wheel is free spinning directly about the rear wheel. You can actaully feel it rock back and forth. Give it a try and you will see what i mean. (its more evident when you give it a medium spin)

    well if that's so then the closer to the center of the wheel the less effect the weight is going to have.

    From what I have heard, one should position the spoke magnet as close to the centre of the wheel (near the hub) as possible. Unfortunately, not all computers come with long enough wires. My Sigma BC1600, for example, doesn't allow wiring down the fork that far. As a result, I sometimes notice an 'imbalance' in the wheel. But it's not something to lose sleep over.

    Yeah, thats what i thought, and i have placed it close to the hub, but i can still feel some rocking momentum. Fortunately my bike computer is wireless! so it is mounted low on the fork.

    Putting the magnet close to the hub reduces its velocity and hence the effects of its mass on the wheel. The sensor on my 'bent is on the front wheel and believe me those little 20" wheels can really spin when I'm cranking. I do not notice the effects of the sensor magnet at all.
