Skaiwerd, I appreciate the recommendation, tho the Suntour seatpost I'm looking at definitely seems to be superior. I've seen quite the number of $20-30 seatposts like that one, they seem to just bounce around... the Suntour appears to do more (or less, when it comes to bouncing). I've actually also seen a number of videos comparing the Suntour to almost exactly the same seatposts as the zoom, the Suntour is always recommended quite a bit more. Considering the bike currently has a pretty nice, super lightweight Easton EC70 seatpost... if I'm gonna replace it, it's gotta be worth it. The Suntour is 3-4 time the weight, tho still not that bad, and if the reviews are accurate, should be a pretty solid suspension seat.
ebike11, I'm definitely interested in that as well. In about a week should have this build complete or very close to, and currently the bike is a single speed mountain bike... definitely hoping it'll work without a derailleur, don;t currently have one.
