It’s impossible to operate any kBox4 or kPulley2 device without a functional Pulley Block. During your training, make sure to absorb all the energy in the eccentric phase of any movement and come to a complete stop before the Pulley Block hits the device since this can cause damage both to the Pulley Block as well as the main device.

Replacing the Pulley Block will involve disconnecting the Drive Belt from your device. This can be assisted by the Drive Belt Removal Tool (pin) that comes with every new Exxentric Flywheel Training System.

The large Pulley Block is more suitable for facilities that cycle through many clients who exert large amounts of force in their flywheel training. Hence it is recommended for the kBox4 Pro and kBox4 Lite platforms.

The small Pulley Block is more appropriate for the kBox4 Active, given that it’s more likely to be used in a home setting. Whereas the kPulley2 benefits from a smaller Pulley Block due to the horizontal angle of most exercises, where the gravitational force of a heavier Pulley Block may cause an undesired effect.


The latest version of the Pulley Block is pre-built with a rubber casing that’s designed to protect it from any impact caused by collisions with the device that it’s mounted to, hence prolonging its lifespan and making it more robust. Moreover it includes an axial roller, which allows the Pulley Block to adapt to any executed movement and maintain its stability under pressure.
