Mr Mud and I each ordered a Turbo
Gravity Dropper through Gene.
Kamakaze told us about
All Mountain PostsAnd then there is also
Speedball posts by Maverick.
Lots of options. We chose Gravity Dropper because we met two people who use them and like them. Anne, one of the two, did mention that Speedball would not work with her bike. I forgot why. So, some homework is necessary here.
Also, you get 10% discount (to $270) if you order through Gene.
