Pedals and Crankset |
|||||||||||||||||||
The pedals are the point at which the rider transmits work to the bicycle. In this section, the bottom bracket, crankset, pedals and chain wheel(s) will be considered as a system for maximizing this interaction with the minimum of energy loss. A diagram of the bottom |
|||||||||||||||||||
bracket, viewed from
above, is shown opposite. This assembly is situated at the base of the triangulated
frame and the central spindle carries the crankset and pedals, and the
chain wheel. The spindle runs in two adjustable cup/cone bearings which
are lubricated and adjusted to provide stability to the shaft while minimizing
bearing friction. |
