Abstract
A bicycle has a spider including a torque input section and at least one torque output section; a crank assembly coupled with the spider through the torque input section and applying an input torque to the spider; a chainring mounted to the spider through the at least one torque output section and receiving an output torque from the spider; a gauge disposed and oriented generally along a tangential direction or a quasi-tangential direction with respect to the torque input section and the at least one torque output section; and a circuitry coupled to the gauge and receiving a signal from the gauge.
Claims18
A bicycle, comprising:
- a spider including a torque input section and at least one torque output section;
- a crank assembly coupled with the spider through the torque input section and applying an input torque to the spider;
- a chainring mounted to the spider through the at least one torque output section and receiving an output torque from the spider;
- a gauge disposed and oriented generally along a tangential direction or a quasi-tangential direction with respect to the torque input section and the at least one torque output section;
- and
- a circuitry coupled to the gauge and receiving a signal from the gauge;
- wherein the spider has at least one arm portion and a central portion, and the at least one arm portion does not radially extend from the central portion.
A spider, comprising:
- a central portion including a torque input section;
- at least one arm portion including at least one torque output section and outward extending from the central portion;
- and
- a gauge, disposed and oriented generally along a tangential direction or a quasi-tangential direction with respect to the torque input section and the at least one torque output section and generating a signal in response to torque transmission from the torque input section to the at least one torque output section;
- wherein the at least one arm portion does not radially extend from the central portion.
