If things aren't running smoothly, take a look at your chain. Dry chains cause more friction and therefore more resistance. Therefore, make sure that your chain is always optimally lubricated. Especially in winter when temperatures are low and there is salt on the road, the chain suffers many times over. It is therefore important to clean and lubricate the chain from time to time.
Im Winter ist es besonders wichtig, die Kette regelmäßig zu reinigen und zu ölen, da Salz und Kälte die Kette stärker beanspruchen können.
