The kBox is equipped with a drive belt long enough to accommodate most users and exercises. However, some customers have requested a possibility to extend the length for certain applications such as overhead exercises and rotations. Hence, we developed the Extension Strap.
The Extension Strap is 25 mm wide and 118 cm in circumference, custom made of polyester and light-weight metal. Weighing only 85 gram in total, the Extension Strap is customised for flywheel training.
