Automated stressing, like the pro’s do. 

The Pre-Stresser operates on a simple yet effective principle: it supports the wheel’s rim while applying a precise and controlled load to the hub flange. This method achieves an even tension distribution among the spokes, greatly reducing the likelihood of breakage.

A standout feature of the Pre-Stresser is its exceptional adaptability and programmability. It comfortably handles a variety of wheel sizes, ranging from 20 to 29 inches, making it suitable for a wide array of bicycle types. The machine is further enhanced by its advanced programming capabilities. You can program specific pressure and displacement settings for each wheel model, ensuring optimal tension for different wheel types. This includes the ability to set displacement and force individually for the drive and non-drive sides of each model, offering an unprecedented level of precision and customization.

The Pre-Stresser also boasts a smart wheel database. This allows you to store and recall specific force, displacement, and dwelling settings for each wheel and flange side. By removing the guesswork, it ensures maintenance and adjustments are accurately tailored to the specific needs of each wheel.

With its guarantee of uniform spoke tension, the Pre-Stresser significantly prolongs the lifespan of your wheels. It spares you the inconvenience and cost associated with frequent spoke replacements or unexpected wheel failures. The Pre-Stresser ensures you can ride with confidence, secure in the knowledge that your wheels are maintained to the highest standard.
