The Garmin Speed and Cadence Sensor is an accessory for the Forerunner series of watches (305, 310XT, FR60 and 405) to allow the watches to double up as bike computers.
The accessory allows for speed and cadence just like a normal bike computer by tracking revolutions of the wheels. The Forerunner watches are highly versatile and can be used for all your training needs.
