Automated tuning for front and rear air-sprung suspension is used in conjunction with a smartphone app. Lightweight, durable and powered by a long-lasting coin cell battery, ShockWiz automatically records and evaluates suspension performance every time you ride The app displays straightforward adjustments that unite bike, terrain and riding style You do not need to ride with your smartphone; ShockWiz stores the data for display on your phone later Use the direct mount version for inverted forks such as Rockshox RS-1 The small, waterproof case houses a highly accurate pressure sensor and microprocessor. You connect it to your fork or shock’s Schrader valve and it samples air pressure 100 times-a-second while you ride. Finely tuned algorithms analyze the changes in pressure to detect undesirable characteristics such as pogo, pack-down or bob, and class their severity. If a characteristic is severe or persistent ShockWiz will determine the adjustment required to fix it – baseline air pressure, air spring ramp, rebound, compression – and display this in the smartphone app.
