ISM seat line. The "Ideal Saddle Modification" was developed by Steve Toll out of Tampa Fl. Steve was another longtime cyclist that had recurring seat "issues" and decided to give a shot at finding a better solution. Through much trial and error, Steve hit on a shape that delivered the comfort and support he was looking for. During a meeting with John Cobb at a triathlon, Steve decided he would bring his designs and prototypes to our labs for development help. With information gained from our TekScan systems and further research which included seat evaluations at the famous European seat lab of Dr. Frank Sommers of the University of Cologne, the first in a series of ISM seats was developed.
