When bumps are encountered by a traditional frame saddle, the foam compresses, the base flexes and the rails flex. The limitation of this dated design is "one size fits all." Actualy the "one size fits all" is for a 220 lb person. The greater your actual weight varies from this 220 lbs, the less the saddle can optimally absorb bump energy. For lighter riders - especially women - the traditional saddle frame is too stiff. Koobi solves the limitations of a "one size fits all" frame and base by placing an interchangeable elastomer spring between the base and the rail. Softer or firmer elastomers can be installed to soften or firm up your ride.

On a glass smooth road, what you feel is the firmness and shape of the saddle. As roughness is encountered, the elastomer suspension absorbs the bumps energy, reducing fatique to your sit bones, lower back, shoulders and neck. Width of 146 mm (5 3/4").

Each saddle comes with 3 of 5 sets of elastomer springs: extra soft (white), soft (yellow), medium (red), firm (blue)extra fim (black) offering up to 4/10 inch of travel.
