I need to buy a need seatpost for my stoker, and she says she doesn't care if it's a Thudbuster and doesn't think she needs suspension. Up until now she's ridden on a cheap "boing boing" suspension seatpost, and our ride is all aluminum. Even though she doesn't think she need a Thudbuster, I'm worried she'll regret not having one later and I don't want to do anything to diminish her comfort and enthusiasm for riding. So, is she crazy? Should I just get a Thudbuster anyway and call it good? Do your stokers prefer non-suspended posts?
