ABSTRACT:
The present application relates to an input torque measuring device for a drive train of a bicycle. The drive train includes a first crank arm and a second crank arm. An inboard end of each crank arm is rotatably mounted to the bicycle at a bottom bracket of the bicycle. At least one chain ring is configured to rotate a driven wheel of the bicycle. A spider is connected to the first crank arm adjacent the bottom bracket and extends out to the at least one chain ring. The chain ring is attached to the spider by a fastener extending through a bushing within an opening of the spider. Sensors may be attached to the spider or the crank arms and may be directly connected to a flexible circuit board. The sensors, the flexible circuit boards and other components of the input torque measuring device may be encapsulated in a protective material.
