ERGOLUX

Please remain seated!

Move weightlessly through the city, easily heading to your destination and feeling the airstream through your own strength, feeling and experiencing nature and the city. In spite of the automobile, motorcycle and space shuttle, cycling continues to be the most fascinating and – as you may know today – the most efficient type of locomotion for 200 years. As part of a research project aimed at developing the perfect saddle, scientists, doctors, technicians and all sorts of cyclists have conducted research down to the last detail and continuously made improvements so that a simply shape can ultimately form the perfect complement to the cyclist. After the second season of ERGOWAVE®, we are now ready to present the comfort variant for cyclists who sit somewhat more upright on their travel, everyday, city and trekking bikes.

ERGOLUX® – more space – more movement – less pressure, ERGOLUX® is the comfort version of the successful SQlab ERGOWAVE® saddle shape. 

Perfect support

The raised tail provides more support at the back, resulting in a more efficient power transfer.

Comfortable riding position

The undulating shape of the ERGOLUX® stretching from the stern to the front corresponds perfectly to the mostly bulbous ramus of the ischium. The enlarged, less selective contact surface, provides for a best possible pressure distribution within the ramus of the ischium.

Lower saddle nose

The lower saddle nose relieves the pressure on sensitive areas of both men and women alike.

SQlab active system comfort

The SQlab active technology enables lateral movement of the pelvis of up to 7 °, which, from a biomechanical viewpoint is similar to running. This increases pedal efficiency and, above all, comfort. At the same time, the intervertebral discs are relieved and mobilized. The lateral movement can be adapted to the rider's weight via the Comfortsticks

The pelvis

When sitting normally, the sitbones support the body‘s weight and have the capability to withstand high pressure. This should also be the case when riding a bicycle. With an athletic riding position, the perineal area of men and the lower positioned pubic bone arch of women on the saddle.

The well branched out network of nerves and blood vessels of the perineal area reaches from the anus via the genitals to the upper pubic bone arch. On the sides it reaches past the pubic bones. 

These are capable of carrying a small weight – but a pressure reduction is essential. An even pressure reduction in the perineal area and the pubic bones is achieved through the lowered nose of our SQlab step saddle concept.

The sitting position

When sitting, the sitbones (areas marked in green) serve the purpose of supporting the body’s weight, hence they can endure a high load and pressure. They should also be utilised in this way when riding a bike.

 

In a dynamic riding position the contact point moves from the tip of the sitbones, forwards along the pubic arch to the pubic bone and the central perineal area is used for resting on for both genders. Women however, typically have a lower pubic arch which can result in higher pressure from the saddle nose when riding in a dynamic riding position. The surface area the riders weight is resting on is especially critical in a very dynamic and forward riding position and in such a case the riders weight should not only be supported in the centre but also on the pubic bone.

 

The sitbone and pubic bones both come together from their widest points in a “V” shape. This means the more dynamic the riding position, the narrower the saddle is allowed to, and should be.

Already in 2002 we developed a simple equation which uses the distance of the sitbone tips in dependence of the riding positing to calculate the perfect saddle width. This method has meanwhile been established globally. The method may be interpreted slightly differently from different saddle manufacturers and many leave the adjustment equation away all together, but our basic concept is used in all of these measuring methods.

 

The flexibility of the spine has much less influence on the positioning of the pelvis as often assumed. Spine and pelvis should remain in a natural position relative to each other and not be forced into a certain position, even if the body is very flexible.

 

Especially with the SQlab step saddle it is no longer necessary to tilt the pelvis backwards as the typical pressure zone of the perineal area and pelvis arch no longer pose a problem due to the lowered position of the saddle nose. The energy which is often required to hold the pelvis upright while the upper body taks a dynamic and forward position is no longer required with the SQlab step saddle and can instead be used for pedalling and propelling the bike forward. In addition, there is substantially less load on the spinal discs.
