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.
