Chainstay Speed Sensor


When Shimano announced the EP8 system Shimano also introduced the EW-SS300 STEPS Chainstay Speed Sensor.

It is installed on the chainstay and utilises a spoke magnet (included) to determine the bike's speed. The distance between magnet and sensor should be 3 - 17mm. The unit comes with a special spacer in case the distance between magnet and sensor exceeds 17mm.
