    Alternate locations for cadence sensor

    Is it pretty commonplace for people to attach the cadence sensor to the chainstay?

    Would I lose any functionality by attaching the sensor to the seattube or downtube?

    Well, you might lose *all* functionality, if the sensor is too far from the magnet. That is why the sensor usually goes on the chainstay, it's the part of the frame closest to the cranks...gets the best signal there.

    But what the heck, give it a try, it might work. If it does, great. If not, you still might be able to rig something up by replacing your magnet with one of those super-strong ones.
    Can you pass the test?

    no loss of functionality. On my Allez, my wireless polar cadence sensor is on the downtube.

    the cadence sensor for my PT Pro is huge. it's almost as big as one of the 2x4 lego bricks turned on its side. It's so big there are clearance issues between the chainstay and the magnet. Sooooo I'll try putting it somewhere else when I get home.

    Switch to a different magnet. You can get a rare earth magnet and put it on the back of your pedal spindle. It will be thinner than the supplied magnet and should give you more clearance.

    The magnet will stick to the pedal spindle (as long as its a steel spindle) without needing to glue it or anything. Then just get the edge of a small screwdriver under the magnet and pop it off. As long as the magnet is big enough not to go down inside the allen key nut on the back of the spindle you should be fine.
