Abstract: A sensor assembly includes a shank shaped for mating with a socket in a head of a bolt about which a portion of a rear suspension of a bicycle pivots. A magnetometer (or a permanent magnet) is coupled to the shank. A permanent magnet with a north pole and a south pole (or a magnetometer) is positioned adjacent to the magnetometer (or permanent magnet) and pivotable relative thereto. A linkage couples the permanent magnet (or magnetometer) to the portion of the rear suspension that pivots about the bolt. The magnetometer senses changes in the magnetic field as the suspension pivots.

Abstract: An elongated pressure sensitive potentiometer is disposed alongside and generally parallel to a reciprocating suspension component, such as a shock absorber, and between a steel track and a rolling or static magnet. The track and contained potentiometer extend from a mount at or near the top of a cylinder of the shock absorber to a point beyond the magnet when the shock absorber is in an uncompressed state. The mount couples the track to the shaft, parallel to and spaced apart from the shaft. Magnet attraction of the track compresses the potentiometer between the track and magnet.
