A crucial component of any kBox or kPulley device, which facilitates your flywheel training needs.

It’s impossible to operate any kBox or kPulley device without a functional Pulley Block. This is the hub between the drive belt on a flywheel training device and any attachment used in an exercise.

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 collides with 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 a 3-mm hex key, which comes with every new Exxentric Flywheel Training System.

The small Pulley Block is more appropriate for the kPulley due to the horizontal nature of most exercises, where the gravitational force of a heavier Pulley Block may cause an undesired effect. Whereas the large Pulley Block is generally used on the kBox , which often encounters larger forces and hence needs to be sturdier.

The latest version of the Pulley Block has been designed to be even more durable, robust & easy to operate with its new locking mechanism for accessory attachment. It is also assembled with a rubber casing that’s designed to protect both the Pulley Block as well as the flywheel training device it’s mounted to from any impact caused by collisions, hence prolonging their lifespan. Moreover it includes an axial roller, which allows the Pulley Block to adapt to any executed movement and maintain its stability under pressure.
