ISM - Ideal Saddle Modification

ISM stands for 'Ideal Saddle Modification' - but also for more power, more comfort, longer endurance, healthier cycling and more fun in sports. These modifications are exact emerged from the passion using a new saddle design to make cycling more efficient, healthier and more comfortable.

The ISM saddles are distinguished by their two-split noses with space for soft tissue and a special ergonomic shape, which allow the pelvis to tilt and thus more aggressive and at the same time to sit comfortable on the bike. The results of this special form are to a high-technical and medical nature. Due to the stronger inclination of the pelvis can produce a higher wattage on the bike and at the same time an even more aerodynamic position. One of the key points is that the pressure of the soft tissues is reduced by the two-split saddle nose and a 100% blood flow is maintained. For short-term consequences of conventional saddles will be taken, such as numbness of the soft tissues, deadened legs and back complaints. Possible long-term consequences will be prevented, such as circulatory disorders, impotence and infections.
