The world of knee pads is simple. The rule of thumb is: the better the cushioning provided by the protector, the more likely you are to survive the fall without any consequences. The knee in particular needs a crumple zone, because where other parts of the body are cushioned with fatty tissue, soft tissue and muscle cords, the knee hits the ground hard and bare. In extreme cases, this means: bone hits rock. The result: bruises, capsule, cartilage or meniscus tears, bursal injuries or fractures of the kneecap. This hurts and usually puts an end to the biking season. So it's better to protect your knee with a protector.
But which one absorbs particularly well? The only way to find out is to subject the protectors to a crash test in the laboratory, based on the standard for motorbike protectors (EN 1621.1). This involves a 5-kilo iron block crashing into a sensor knee from a height of one metre.
