PRS Alpha Saddle is the ultimate distance saddle and features breakthrough
"tunable suspension." Below the sleek leather and firm padding is Koobis 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 his or her own personal ride preference.
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." Actually the "one size fits all" is for a 220 lb person. The greater
your actual weight varies from 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
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.
saddle comes with 3 of 4 sets of elastomer springs: extra soft (white), soft
(yellow), medium (red), and firm (blue) offering up to 4/10 inch of travel.
(For cyclists riding over 8 hours per week and are accustomed to a firm saddle)
