It's easy to see how the ShockWiz could become an invaluable tool...simplifying a process that to many seems like a dark art. 


ShockWiz was a Kickstarter project acquired by SRAM in 2016. SRAM’s data and digital technology brand, Quarq, brought ShockWiz to life. Engineers behind Quarq and RockShox, also part of the SRAM family, worked on the project.


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.

The engineering principles behind ShockWiz were derived from thousands of hours of laboratory and on-bike tests. The tests verified that suspension displacement could be interpreted from changes in air pressure. ShockWiz’s algorithms came from detailed analysis of suspension data from all types of mountain bikes and terrain, and using a range of riders – from beginners to racers in the Enduro World Series and Mountain Bike World Cup.

Who Is It For?

ShockWiz is designed for all mountain bike riders, regardless of their riding style or how much suspension travel their bike has. It works on hardtail and dual suspension bikes, and for all levels of skill, speed and terrain.

ShockWiz teaches novices basic suspension tuning concepts and adjustments. It shows experts how one adjustment can affect others and helps them learn advanced tuning concepts.


ShockWiz works with most air-sprung suspension forks and rear shocks. The fork or shock must have a positive chamber with a single volume.

The ShockWiz app is compatible with most smartphones and tablets that feature Bluetooth Low Energy (formerly called Bluetooth Smart). Android devices require Jellybean 4.3 or newer and Apple devices require iOS 9 or newer.

See the Online Help for more on compatibility.


Quarq has launched a major upgrade to the free app that pairs with its ShockWiz suspension tuning hardware. You can save profiles of your bike, suspension, terrain and conditions, and automatically add settings, suggestions and a results snapshot.

Other Considerations

Forks and rear shocks must be in good working order for ShockWiz to work effectively. This includes cleaning, dust seal lubrication and oil changes as prescribed in the user manual.

Pricing and Availability

ShockWiz is available from the Quarq website for customers in U.S.A. and Canada, from bicycle dealers throughout the U.S.A., Australia and New Zealand, and from select online retailers. Over time we will add more places to see, try and buy ShockWiz.

The ShockWiz hardware is currently certified for sale and use in these countries.
