Rohloff Cleaning-oil and speedhub-oil for the Speedhub 500/14.
An oil change should be annually carried out or at least every 5000km.
Through this process it can be safe to say that there will always be enough oil in the hub regardless of oil loss (due to sweat oil) and that any penetrated water will be rinsed out.

1 bottle Speedhub oil 25ml / 0.85 fl oz (art.no. 8403)
