As you may already know I am very much into finding the most effective (in terms of improving comfort) bike parts. I already tested many suspension seatpost so I had great expectations towards a seatpost made by the same company that has created a suspension stem. And after all of my testing, I can say that this seatpost really works well in terms of comfort improvement but this is still a spring suspension so you have to do a lot of fine-tuning to make it work best for you. If you are interested in more detail just read my review:

And if you have any questions just ask me. I will be doing a big suspension seatpost shootout in coming weeks so I can check/test things you want.
Cheers!
