Maintenance: chain

Make sure that the chain is always clean and that it has the right tension. Always keep it greasy, a dry chain will rust and will rotate difficulty. A chain that is worn out will damage the drive sprockets.
The correct tension is measured by pushing on the chain in-between the two sprockets. You should be able to move the chain 1 to 2 cm (0.395-0.79") down- and upwards.
