There is an old Cascade at River Sports in Knoxville, Tennessee (865-523-0066)with a cracked cock pit rim. It has been there for a least 4 years drying out in the sun and weather.
It still has the foam, perception saddle, and the hip hugger attachment intact.
If you are interested and need those items, I would call them and offer $100. THey were asking $250 three years ago. Ask for Ed or Rena or a manager otherwise you are wasteing your cellular minutes.
