I know some variant of this question has been around before, but... I just got some Hed 3 wheels for racing (I have velocity deep v's for training). I have an ancient cat eye vectra computer with the sensor attached down by the quick release. The only way that I was able to the computer to work was by using a magned that was about 1/2 inch thick and rotating the sensor significantly in toward the hub. so I went and bought myself a brand new cat eye computer with the new sensor that mounts only using zip ties. Can't get this one to work at all with the Hed wheels. Anyone have a computer that works OK with both velocity and HED 3 wheels.
