Chain guide
Chain guidance is a term used in motocross and in the bicycle sector, mainly in downhill sports and enduro.
background
Since the chain is exposed to strong vibrations in off-road use and there is a risk of it jumping off the sprocket or chainring , it must be held in position with a chain guide. In the field of bicycles, the guide consists of two parts: the upper part, which only a guiding function of the load strand accepts (driving side) and the lower part, in addition to the guide and a clamping function of the empty strand obtained.
However, with the introduction of 1x11 and 1x12, the drives themselves have greatly improved in the mountain bike sector in recent years. Friction-damped rear derailleurs are standard and the chainrings also have a tooth profile that changes from narrow to wide, which guides the chain. Nowadays, a chain guide that only secures the load strand is usually sufficient in racing.
