I am attempt to install a Cateye Astrale 8 wired computer with Cadence on a Specialized Globe City City 6 ING 8.

Cateye manuals says that Magnet and Sensor gap should be no wider than 5mm - approx. 3/16".

The gap between the left rear chainstay and spoke is approx. 1 1/2". The gap between the sensor and spoke magnet is 1/2". What can I use to extend the sensor closer to the spoke magnet to get it under 3/16".

The same gap of 1/2" is between the left rear chainstay and the left pedal crank. What can I use to move the magnet on the crank to get it under 3/16".

Thanks, Gil
