Seat Post shock worth it?

Postby Shane_Thompson86 » Mon Jul 20, 2009 12:53 pm

I have a hard tail, and I was wondering if those Seat posts with shocks built in are worth it. Those downhill sections with erossion root expouser are very bump with my bike. I stand up on these bump sections and ofcourse use my legs as shocks, but I think I would still stand up even a seatpost shock. Just wondering if that thing would be a waist or worth it.


Thanks In advance!

One of my riding buddies has a Thudbuster seatpost on his Specialized HT, and he swears by this thing. I tried it riding for a while and it was just like having a 3" rear travel shock. I have also seen these more often lately especially after my buddy moved to GA.

Here is another one I have seen on other riders HT's, but this one mostly on those bikes of hardcore XC racers and roadies.

I personally would definitely recommend going with one if you are riding on gnarly terrain on your HT. As per DH runs (long or short) you should be off and back from your saddle instead of sitting on it. As a retired semi-pro DH competitor, I can vouch for that. You would have more control of your bike by doing this bro. Anyways, good luck bro!


Nice, yea I want one of thise for my B-day lol. Which one do you recomend? The worst terrain i get into is just abunch roots petruding about 5-2 inches obove the ground on downhill sections. High enough to make me have to stand up even then its still rough.

One thing I am not sure about is would I still stand up anyways on these sections for some reason that feels like the best/natural thing to do, Or is sitting down on downhill the proper thing? Not quite sure, because I know if i was sitting down the rear wheel would have more weight over it and would not be bouncing all about :shock:

If it was me to choose, I would go with the Thudbuster seatpost (first one), because I know what it feels like and it offers 3 inches of travel. If you don't like it or it does not feel good, just return it bro. Once I get my AM HT in a few months, I will be putting on one of those Thudbusters. Now, as per the DH, you are best getting off your saddle, leveling your cranks, and getting your butt back. You should go to the DH/FR forum and check out the DH topic that I put together.


Nice yea thats the one i figured i would need also. I will check that area out, and thanks

A buddy of mine was telling me that these things are no good to have, for its not good for the position between the feet and seat to be changing at will. what do you guys think about his view?

If you want to look at it from body position efficiency standpoint he has a case, albeit a small one. The most efficient position for you to ride in will have your seatpost up at a height that allows almost full extension of your legs as you pedal. A shock will bounce up and down a bit and change that distance as you pedal.

HOWEVER, a stiffer shock will not bob that much when pedaling and will mainly be used for absorbing bumps. When absorbing bumps, it actually makes for a MORE efficient ride than a fully rigid rear end because it keeps the wheel on the ground and lets it track over the obstacle. A rigid rear end hits the obstacle and bumps up and over it and can temporarily lose contact with the ground.

I'd never use one on a road bike or something I planned on riding smooth surfaces with. But mountain biking isn't about riding on a smooth paved road, is it?
Looking for inspiration, everyday.

There's nothing a man can't "fix" with the right size hammer.

Yeah,I would have to say that these seat post shocks WILL change the distance from your hips to your feet and make you squat more than what your desired seat height shoule be.So,in fact when you are riding in rough and tough terrain where you will need sudden burst's of pedal power to get up and over square edge bumps and such that your knees over time might take a beating because of the lower squat at the bottom end travel of the seat post shock absorber.Like Chilipepper said,you'll probably be standing in these situations but you wont be standing all the time and will encounter times where you'll be seated and find one of or both of your wheels in a dip or rut and need to power your way out of it by putting the hammer down where your knees will by under preasure while the seat post is at it's bottom travel.I dont know though,I have never owned one of these seat posts,but I would think the amount of travel is minimul enough along with the way a mountain bike is ridden anyway by ever changing terrain and seat/body position that it is o.k. to use one of these seat post suspensions.
I dont think I would use one of these for the trail,but maby urban riding and cummuting back and forth from work it might be nice,you got me thinking about one now.hahahahahaaha.
I just bought a seat post dropper made by specialized that has a remote on the handle bars,but it is not a suspension seat post,it just has a three postion lock out so you can lower it out of the way when decending down steep hills and drops.

Thanks for the info all guys. I believe I may hold off on this purchase, for it is rather pricey for me. I think I could find a more effective way to spend $150.
