Prostate problems

Bicycle saddle for prostate problems?

After a prostate operation or in the case of frequent prostate inflammations, it is crucial that the saddle does not exert pressure on the sensitive perineal area.  Die Sattelmodelle 621 M-D active und 602 M-D active  bietet eine bestmögliche Entlastung im Dammbereich und werden nach Prostataoperationen empfohlen.



If you have a prostate problem see a doctor!

The prostate is a chestnut-sized organ and consists of glandular, muscle and fat cells. It is located immediately behind the soft tissues of the perineal area and lies below the urinary bladder and surrounds the urethra. Men over the age of 45 should go for regular check-ups, because the prostate is an organ that can grow constantly. In addition, the risk of developing prostate cancer increases with age. 

This often causes problems in old age, because the older men get, the higher the probability of being affected. In the course of time, recurring urinary tract infections (pain when urinating) may also occur, making it impossible to sit on the bicycle saddle without discomfort. In the case of prostatitis, pressure on the perineal area must not be applied under any circumstances.




If you have had prostate surgery cycling is only recommended after a certain time – if at all – and with a saddle like the SQlab 600 active.

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.
