Our ultimate distance saddle features breakthrough "tunable suspension." Below the sleek cover and firm padding is our state of the art "tunable suspension." This simple to tune, light weight suspension uses proven elastomer spring technology, allowing the rider to tune the suspension to their personal preference.
When a traditional saddle encounters road bumps ,the foam compresses, the base flexes and the rails flex. The limitation of this dated design is "one size fits all." Actually the "one size fits all" is for a 220 lb. person. The greater your weight varies from 220 lbs. the stiffer the ride. Manufactures compensate for this stiffness by building with ever softer foam, which has a tendency to collapse during a ride. The rate of collapse is based on the riders weight, the density of the foam, the length of the ride and the age of the saddle. By building a saddle that gains comfort from a base that is correctly tuned to the riders weight, the limitations of collapsing foam is avoided. Koobi does offer the PRS Century, and PRS Enduro with softer foam.
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 fatigue to your sit bones, lower back, shoulders and neck. Width of 146 mm (5 3/4").Firm padding , Titanium rail, 294g, women's model available. For the cyclist consistently riding over 6 hours per week.
PRS Alpha has an exceptionally durable cover, requiring 30 hour break in.
Each saddle comes with 1 of 5 sets of elastomer springs: extra soft (white), soft (yellow), medium (red), firm (blue)extra firm (black) offering up to 4/10 inch of travel. Koobi custom builds each order, installing the correct elastomer for your weight.
