A system for adjusting the damper force on the suspension system of a bicycle is provided. Sensors are placed on the front shock and rear shock to measure the amplitude of displacement or acceleration in the time domain and generate a zenith position, velocity, force, and work based on the measured values. The system calculates a curve fit approximation curve for the relationships of zenith position versus velocity and uses the approximation curves to generate and display recommended damper settings for the front shock and rear shock. Using the data ensures that the bicycle suspension data is balanced, such that the front shock and rear shock respond similarly to the same event.

System for balancing dampening forces on a suspension system

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.

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.
