Bicycle crankarm having a stress/strain detector for a torque meter or a power meter, and methods for manufacturing and using the crankarm

A bicycle crankarm the bicycle transmission side that has a main body length measured along a length from a crankset's crankarm rotation axis to a pedal axis. The crankarm has at least one stress/strain detector oriented along the length direction at a fixed distance, measured from the center o...

Beschreibung
Zusammenfassung:	A bicycle crankarm the bicycle transmission side that has a main body length measured along a length from a crankset's crankarm rotation axis to a pedal axis. The crankarm has at least one stress/strain detector oriented along the length direction at a fixed distance, measured from the center of the stress/strain detector to the rotation axis of the crankarm, such that the ratio of the distance and the length is in the range between 0.45-0.65.
