err...i was never a fan of suspension seatposts or stems. how much would you pay for a 1" - 1.5" of travel of your seatpost? i'd rather get a thomson, stand on my cranks and let my body take the shock  |

its nice and might just be as good as my thudbuster LT. I've been looking for the suntour seatpost but cant find one, so i settled for the thud (bought it in velocity cartimar)

Considering the location of the suspension and the really short travel, wouldn't these seatposts be just the same (in many respects) as the old spring equipped comfort saddles? I doubt they help significantly with downhill traction and control as FS frames are supposed to do. |

Suspension posts are there to provide comfort and not really to improve downhill traction or performance. They're supposed to take out the "edges"/smoothen the ride when you ride over rocks and roots as with thos old comfort saddles. They might work slightly better than those old comfort saddles though. For one, I think those saddles are way too wide that they prohibit your movement around your bike.
I've installed a cheap suspension seat post on my hardtail and yes it did make a difference but it's still not the same as riding a full suspension mtb.

gilbs72: the function of the parallelogram and the thudbuster is to isolate the force of the object under the tires (upward force on your a$$). Instead of a spring, those 2 uses 2 parallel bars to drop you behind the seatpost so when the rear tire of the bike raises you stay in the same path. (unlike a ridgid seatpost) you will be, if exagerated will be ejected to the front of the bike. The bike rotates leaving you on the same level (on the front tire). Spring suspension seatpost gives the idea that it is the same but actually it isnt. It will still jerk you forward when the bump is on the rear of the bike. There is an animation there demonstrating this movement. Just check it out.

in my experience, i felt less tired and less aches when i use my thud. its just like a full sus bike except that you have to stay seated.

There is an animation there demonstrating this movement. Just check it out. With the telescoping suspension seatposts like Rockshox, definitely the parallelogram is superior because the motion of the telescoping seatposts work directly toward the center of the saddle in a single line (no absorption for the forward movement). In my earlier post, I was wondering about the old coil-sprung seats we used to have on our trekking bikes, cruisers and comfort bikes (and sometimes on "batotoy"  . Since the two springs are in the rear of the saddle, wouldn't they actually act on bumps the same way--against the 'rotating' forward, upward motion--like the parallelogram seatposts? Come to think of it, if you pair the telescoping seatpost and the spring seats, you have a parallelogram. Heavy though!   |
