ERGOWAVE

Performance Based Ergonomics

The shape - developed in a research project and in collaboration with the University Hospital of Frankfurt and the Frankfurt University of Applied Sciences. Government funded by the Federal Ministry for Economic Affairs and Energy. For the first time, we were able to calculate the forces occurring deep within the structures of the body and the maximum load between the cyclist and the bike saddle. The final result is the new ERGOWAVE saddle shape for a more ergonomically agressive sitting position on the road and mountain bike, with the top marks among the maximum load in all tests.

Perfect fit

The correct width saddle is a prerequisite for maximum performance.

Available widths: 12 / 13 / 14 /15 cm

Sleek rear

The raised back section provides more rearward support and ensures efficient power transmission.

Saving Energy

The wave shaped ERGOWAVE® profile which contours from the rear to the front offers a perfect form-fit shape for most sitbones. The rider does not need to be seated in an inefficient and tiring sitting position and all energy can be used for forward propulsion.

 

Lower saddle nose

The level and lowered saddle nose applies less pressure to the sensitive areas of men and women alike.

Biomechanics

Pelvis movement of up to 7° is made possible by the SQlab active Technology, which from a biomechanical point of view simulates the natural movement of walking and increases the efficiency of the pedalling motion. At the same time, the spinal discs are relieved and the pressure to the sitbones is reduced.

Adjustable active Technology

The proven SQlab active technology has been adjusted for race and MTB applications and is now firmer.
Available in three densities: soft/medium/hard

 

Center Dip

The slight dip in the center of the saddle reduces pressure to the sensitive tissue areas of the perineum. 

Low and flat

The flat saddle nose has a slight curvature which provides maximum contact area providing and associated reduced pressure. This shape provides a narrow saddle nose which minimizes chafing on the inside of the thighs while pedalling. The SQlab MaxContact® concept has proven valuable in other race models over the years and has been improved for the new ERGOWAVE® models.

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.
