    This is the best suspension seatpost ever made in the history of the world:SR SUNTOUR

    I have herniated disks and like a cushy ride but I don't like the drawbacks of a full suspension bike. I have tried nearly every suspension seatpost made from the Tamer Pivot Plus aka Tricky Dick, to the two different Thudbusters(long & short travel) to regular designs. Either they don't do enough or they feel like a bouncy diving board. None of them felt quite right. The SR Suntour suspension seatpost transforms a hardtail instantly into a full suspension feel without any pedal bob.

    The SR Suntour parallellogram design is the smoothest and most effective design for medium to large off road bump supression and a $ $ redemption.

    It sucks that it's not readily available or marketed in the United States. I have used one that came stock on an old K2 bike for 3 years and it's finally wearing out but still functional. To order one you can sometimes get lucky on E-bay but I went straight to the SR Suntour USA distributer Doug Stuart.

    Why didn't you like the Thudbusters? I am looking at a suspension post for my commuter. Also how much did the suntour cost you?

    The prices range from $40 -$70 depending on which version you get (steel vs. alloy)

    The Thudbusters are big heavy beasts, expensive and not easily adjustable or fine tunable based on weight/preference plus they boing like a diving board. This one adjusts spring tension in fine increments with a allen wrench adjustment screw at the bottom end of the seatpost. I set mine rather stiff so it only activates when I come down hard on my butt never when pedaling.

    The SR Suntour is the closest feeling to Full Suspension dampening on a hardtail.

    holy set-back, Batman! I could never get that saddle in the right position for me...even with the saddle rails all the way forward like the pic shows. That will screw it up for a few folks. Consider that before you order one.

    Otherwise, it looks tidy and clean.

    I mean i think I'd rather eat Megan Fox's ass than have my ass electrocuted in sulfuric acid for an hour or so, then dyed, and boiled for 20 minutes.

    Surly a thudbuster would have a preload adjust for the amount of money they want for one.
    I don't see spending $130 or more on one with no Preload adjust. I'll have to check them out closer now. The Suntour does'nt look too shabby for $80!

    It seems to me (after checking out the specs on the Thudbuster), that you can only adjust for the weight of the rider. There is no tweaking adjustment at all. You have to replace the Elastomers to softer or harder according to your weight and thats the only adjustment you have. I may be on a trail and decide to stiffen it up a bit and won't be able to with that type of set-up. I also like the piston and roller design of the suntour much better just by looking at the two. I think I would have to go with the Suntour for sure! Better price really seals the deal also.

    i'm a big fan of the white bros air post. It's light,it has an oil damper. 27.2, I
    used to shim it out with delrin sleeves top and bottom on bigger frames. My back got better, these days i only use one on my powercrank bike. I have extra's, i had one rebuilt and bought the last one they had at white at a nice discount. It doesn't have the parallelagram action,but i use it for roadbiking,i'm fine with suspension on a mountainbike.

    minimum seat rail height?

    The Thubuster does have a preload adjustment see http://www.thudbuster.com/pdf/Thudbu...structions.pdf

    This Suntour looks promising. The thudbuster LT minimum seat rail height is 144mm above the seat tube. I need a seatpost for my stoker on a tandem and need the seat rails much lower than 144mm.

    What is the minimum seat rail height above the seat tube for the SR Suntour?

    nice and low, but can you get softer springs?

    Now only thing is my stroker is 120 lbs and the manual shows suggested rider's weight 144 to 220 lbs (65 to 100kg).

    The manual lists softer and harder springs. I wonder how hard it would be to get/find the softer spring?

    Your right...I missed that 2nd page when I viewed it. I still like the design and price of the
    Suntour better though. I would like to know the weight of the two and I can't seem to find
    one for either of them. I'm going to take a wild guess and say the Thudbuster is lighter?

    Talk to Doug at Suntour. I'm sure he can hook you up, though I don't think there should be a problem with the stock spring. Backed all the way out, I can compress it just by pressing on it, and I'm sure you don't want it that soft.

    The way I read the OP's comments, it sounds like he says the Thudbuster weighs more.

    LOL, like you have a clue what you're talking about. If you like something, great. Slagging a product you don't have any idea how it works is stupid. TB has been around for years, ride your SR for a few weeks before you proclaim it the best in the world.

    Thudbuster LT 30.9mm is 586 grams.

    I loved mine. Haven't used it in a couple of years, though. Preload adjustment definitely helps with the bounce. I also found I preferred the stiffest elastomers even though I'm only 160lbs. That pretty much eliminated the bounce for me and still provided plenty of cush.

    Cane Creek service is the best. They've treated me right on several issues, and as a result I use CC components whenever possible. I wish they'd expand their line - cranks, BBs... I'd be first in line.

    I've never used either of them. I'm trying to make a comparison of the two. And I never said it was the best in the world. I did say I like the design and price of the SR and don't have $130 for a TB. If you have things good to say about TB then post it here so we can get more than just opinions about the SR.

    One thing I do know is that both of them are better than my Kalloy that is just a couple tubes and a spring.

    Haha that thing is awesome. (In reference to the post apparently below mine now)

    I wouldn't consider it suspension travel since you really aren't seated while going downhill anyway. I couldn't imagine the hit that thing would absorb that I wouldn't be prepared for by standing.

    True Suspension Seatpost

    Here is my engineering senior project that I just completed. Still in the testing/refinement stage but it is far and above better than the Cane Creek Thud Buster (which I own and have ridden). This is as close a hard tail can be to full suspension in my opinion. Fox Float R for resistance and damping. Estimated 4" of travel measured on the radius of the arm length.



    This is the best suspension seatpost ever made in the history of the world:SR SUNTOUR-seat-post-003.jpg

    True. I guess I would say ass travel or taint saving travel. I haven't taken it on any rough trails yet. Gone off a few curbs and it soaks them up easily. The rebound damping is what I was looking for.

    That looks interesting. I know my knees would hate 4" of saddle movement, they get pissed if my saddle is 10mm lower than it should be.

    Not hating, but do you ride with hernias? 4" of saddle travel plus a beach cruiser saddle. Can you steer your bike with your hips anymore?

    Cool project nonetheless. My point on the steering is that you use a lot of balance on a bike when using extremely squishy saddles. The subtle balance of weight shifting on your hips is lost when there are multiple inches of gel padding below your hips.

    The saddle height to center of the bottom bracket distance remains relatively constant. No hernias and fortunately this prototype is on my wife's bike. I have only limited time on the prototype because my wife's bike is way too small for me.I ride a large 2010 Santa Cruz Blur LT.
    The side load rigidity is pretty receptive to steering with the hips. I agree that 4" of travel on a seat post is a little much. This simple prototype was made as a starting point and I think the travel should be reduced to around 50-75mm. The project was me just testing out my design for manufacturing, and CNC machining skills. Next project is full suspension frame.

    Suntour Suspension Seatpost

    I'm willing to try the Sountour SP8 NCX seatpost and if it does the job, replace my Thudbuster but here is the situation; My bike (Breezer Cloud 9 Pro Team Edition) uses a 31.6 seatpost but I guess there must be some sort of reducer or converter, am I right? The other thing is where do I buy it? Does it come on 400mm? or only 350mm?
    Thanks for your help...
