CYCLE CRANKS, CYCLES, METHODS OF MEASURING A CYCLE CRANK ANGULAR POSITION

摘要

A cycle crank comprises a first portion for attachment to a cycle and a second portion spaced from said first portion for attachment to a pedal; wherein said crank comprises a sensor for determining, in use, a value representative of a force applied to said crank; an angular rate sensor for determining, in use the angular rated of rotation of said crank; and a processor for determining the angular position of said crank from said determined angular rate of rotation and associating said position with its corresponding value representative of a force applied to said crank.
