Features the same construction as other Solo seats but with a deeper side profile contour for bikes with steep backbones. Heavy-gauge stamped steel pan with a gently sloping rear kick for added support. Stamped-in ridges increase stiffness. Cover is hand-stitched, heavy-duty black vinyl with molded polyurethane foam. A unique carriage bolt system allows builders to fine-tune the location of the seat hinge and springs. Measures 13" L x 10" W.
