My spine has been being turned into sausage meat. Its the fault of the roads. I have good rear suspenders. Yet when I use the Maverick Customs solo seat I feel every single pump. Don't get this seat wrong. It is great for cruising around on normal roads.
So I bought a new not used second hand Trumpy solo seat today. Nearly half price of a new one. Score. My spine bonces on this now when I ride the goat tracks of New South Wales.
