4. Eliminating the suspension spring makes for more pedal bob.
5. There seems to be a certain amount of pedal bob in the 'post' part of the seatpost.
6. A softer suspension elastomer destroyed itself.
# 2: I don't have a Thudbuster on it, just the original kalloy post.
# 4: Not entirely sure what you mean, perhaps you meant less bob?
# 5: See 2
The Thudbuster is installed on my R20. That other thread of suspension vs thudbuster is probably what caused confusion.
I purposely bought a 27.2mm version Thudbuster with shim for the R20, so I can use it on this or any other bike if I wanted to.
