Hammer Vario crank

Thanks to 12-fold length adjustment, the crank set offers a wide adjustment range from 55 to 175mm. The robust stainless steel construction is corrosion-free and guarantees durability. Tool-free adjustment allows the pedal arm length to be quickly and easily adapted to individual needs – ideal for therapeutic use.

With conventional ergometers, training requires a flexion and extension angle of the knee and hip joints of approximately 110° to 120° – a range of motion that is difficult for many rehab patients or people with degenerative joint changes to achieve. The crank set offers the solution here and makes it possible to adapt to reduced mobility. This means that even with limited knee flexion, efficient, pain-free and safe endurance training can be carried out.

Pedals not included.

Compatible with the following models: Hammer Ergometer Presidio, NorsK Spheris 4.0, Spheris 4.0
