The F100-chain oil has a very good lubricating effect! I have therefore taken the oil bottom bracket and fork next to the chain of my mountain. The oil spread to both the sprockets and on the fork as if by magic - if I einsprühe only one side it wanders around and automatically generates its effect thus also to seemingly unreachable locations. It was obviously easier to drive after oiling the parts, with a little less effort (and I must say that the bike is almost new and was therefore without the oil very easy to move around already).
I would buy it in any case again. PS: Here are 2 more favorable than in our bike shop! ;-)
