The Rohloff SPEEDHUB 500/14 is initially filled with around 25ml of Rohloff SPEEDHUB oil. This exact amount of oil is optimum for both the bearings and gears of the Rohloff SPEEDHUB 500/14. An oil-change must be completed every 5000km or once per Annum to ensure the 12.5ml quantity of oil is retained and is free from dirt/moisture contamination. This process ensures that the SPEEDHUB 500/14 will always contain enough oil for lubrication (regardless of oil lost due to sweat oil) and also ensures that any penetrated moisture is rinsed out.
