Bisiklet

Chains should be a lesson to wear prematurely. The bicycles of today have offered depending on the model, a chain circuit up to 30 courses, of which only 12-13 really use (construction). Compared to Hub circuits are chain circuits only during the Tretens switchable. Despite all the advantages and disadvantages is the chain Circuit much more widespread, as they easily built, and a higher efficiency.

Hub circuits are usually with 3-14 passages. Previously hub circuits weighed significantly more than the current maximum of unique design was of great importance. Because both types now weigh almost the same.

Nevertheless, hub circuits are far more expensive in the acquisition. But they are less rotating and have a very low wear, they have a high level of translation and have much less maintenance costs by less pollution (closed structure within the hub of the rear wheel).
