Stem Alignment Tool – Modular System

Stem Alignment Tool – Modular System

Precision matters. The Velotechnics Stem Alignment Tool is a purpose-built solution for professional bicycle mechanics and dedicated cycling enthusiasts who demand perfect cockpit alignment every time.

Designed by Velotechnics and precision 3D printed in high-strength ABS plastic, this tool makes stem alignment fast, repeatable, and accurate. By indexing directly through the front axle, it provides a stable reference point to ensure the stem is perfectly aligned with the front wheel — eliminating guesswork and saving valuable time in both workshop and home garage settings.

The modular design supports a wide range of bikes through interchangeable adaptors, making it suitable for road, gravel, MTB, and older quick-release setups. Optional extension pieces also allow compatibility with taller cockpit configurations commonly found on modern mountain bikes.
