Rohloff Speedhub Oil Change Kit Specifically formulated for the Speedhub. Oil change kit includes syringe. The Rohloff Speedhub 500/14 is filled with 25ml of Rohloff Speedhub Oil. This exact amount of oil is optimum for both the bearings and gears of the Rohloff Speedhub An oil-change must be completed every 5000km or once per annum to ensure the 25ml 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
