The BMD 250 Obelisk II truing machine is a fast, user-friendly truing machine with two operating nipple keys. The use of modern techniques, such as brushless servomotors without gearboxes, using digital controllers, means that the Obelisk can be set with great accuracy. With a production speed of 40 to 100 wheels per hour, the Obelisk is one of the fastest machines of its type.

Whether you need to true

aluminium rims,
carbon rims
or e-bike rims

you can trust our proven truing machines.

With a production speed of 40 to 100 wheels per hour, the Obelisk is one of the fastest machines of its type.

In the obelisk truing machine a stabiliser module can be incorporated into the housing if required. This set up allows stabilizing without extra handling, wheel buffering or logistics. The Carbon version of the Obelisk truing machine features specially designed hardwearing plastic rollers and contact surfaces.  These provide complete protection when working with this more easily damaged material.

The graphical user interface makes operating the Obelisk intuitive. Use of computers enables collection of production data over a long period. The data can be transferred to your production system via a network connected to the machine. Remote operation and diagnosis are also possible.

The Obelisk’s brushless servo motors without gearbox, utilising digital servo controllers  guarantee a maintenance free, accurately controllable drive to the nipple keys, with continuously adjustable torque. This means that the wheel quality can be more accurately supervised, substantially increasing the quality. The non contact system for measuring wheel hop and wobble reduces maintenance even further.
