Suspension Seatpost(8 posts)

OK, so I don't care about how I look, I don't care about what my bike weighs. But I think I may need a suspension seatpost for my Road Bike. Yes, I have an extremely high end road bike, and I want to stick a suspension seatpost on it because: My "sitting place" wears out long before my legs or lungs do. Yes, I have been professionally fitted; Yes, I have ridden (mtn & road) for years; Yes, I have just about tried every saddle there is. I am tired of not riding far enough or long enough just because my "special place" is killing me!!! I have been disregarded at bike shops, dissed on discussion boards, etc. Is there anyone out there (probably a girl) who has tried one, did it work, what did you try? I can't be the only one...in fact I know there are other girls who are in pain all of the time. I am suspicious of those who say I'll get used to it...I never have, and I don't trust anyone who thinks I should wait for parts of me to stop feeling. Not my idea of a quality life. Good advice, please.

Sorry, I have no experience with suspension posts, though they have gotten good reviews for tandem stokers. However, they are for taking the sharp edge off bumps, and may not at all solve your problem, which seems to be more of a continuous pressure issue. Consider wider and softer tires to get some of the effect of a suspension post without the cost/weight penalty. Depending on your weight, you may be able to drop your tire pressure quite a bit as an experiment. You need to know whether it is truly the "hits" that are the source of your discomfort. If not, then a different path must be pursued. The general principle for saddle comfort is that your weight should be on your "sit bones" and not on any other part of the body. This may be a saddle fit issue for you (getting the right firmness and width to match your rear end) or it could even be that you are not sitting on the saddle properly. You'd think that you wouldn't have to learn how to sit on a bike seat, but think about those sit bones and think about whether you are resting your weight on them or on some other part of your anatomy. Hope this helps.

I agree about trying softer tires instead of a suspension post. I weigh 190 and I run 700x23 tires @ 85 psi front/90 rear. This is much lower than many posters on this board, yet I've never had a pinch flat and gain both "suspension" and better pavement grip. I run a suspension post on my mtn. bike, but as Kerry says, they're for hits/bumps, not taking continuous pressure off your perineum.

One saddle my wife likes is the Selle Italia Max Trans Am Ladies--tried that one?

I use a suspension seatpost on my "around town" road bike (a mid-80s cannondale w/dura ace). It's a low end no-name that I picked up for about $35-40.00. It works just fine except for a bit of seat wiggle. I imagine that a high-end post would'nt have that problem. I agree with the other posted reply that wider, lower pressure tires will also help, try a combination of the two. Have you tried adjusting the tilt on all those saddles? Have you tried women-specific saddles (Terry comes to mind)? PS - I am not "probably a girl" but I am concerned with comfort.

When I got a Thudbuster for my mountain bike, I put my old, cheap Supergo post on my Atlantis just to see how it felt. I intended to go around the block and take it off, but somehow I never got around to it and now it's a year later. Works fine, though as someone else said, it's mainly efficient at taking out the little bumps and buzzies.
I also use 32mm tires (I weigh 225, so I can use the cush) and a Brooks B-17 saddle, and the Atlantis is a comfortable frame anyway. With all four of those things working for me, it's by far the most comfortable bike I've ever ridden.

I was using the same seatpost and seat for two bikes. I was having a prostate problem I developed from mtb riding. Back then they didn't have a lot of seat to releave pressure in that area. I used an USE and it helped on my raleigh bike, since the bike was four years old and riding harsher at that time (stress factor on the frame).

I then switched to a different bike, but tried a different seat and tires. I use the same seat as ken2 wife the Selle Italia Max Trans Am Ladies. I have a wider sit bone, so it works better for me. The seat changed worked better for me than having the suspension seatpost.

Sounds like you haven't found a good seat for long rides and a good tire that rides to your liking. Some people go with 25c tires to ride more comfortable and run 5 psi less than max tire pressure.

Hope this helps.

Be careful with the suspension post idea. Try the lower tire presure and different seats, including well padded seats. Don't be concerned about seat weight. I have an expensive suspension post on my MTB--Moxey Pro--it works well for off-road bumps; however, when I put road tires on this bike and do a ride of any length on the road, I have some pressure problems. The spring action of the post is always pushing up against your tender areas. You really have to lift up to get away from this pressure, and I think it is worse than a regular post for road use. Good luck.

1) How much do you weigh?
2) What is the type, CC's, and TPI of the tires that you are using?
3) What type of front and rear wheels are you using? (Are they three cross? Radial?)
4) What is your frame material?
5) What type of saddle are you using, and what is the density of the padding?

What I am trying to get at, is that there are numerouse factors involved with comfort. A suspension seatpost does help a lot, but there are many factors that are also involved. A radial laced 10 spoked non-drive side rear wheel will feel more bumpy, and you'll feel more road vibrations, than a 4 cross, 36h drive side and non drive side wheel. Also, a steel or Ti frame will be slightly more flexy, than AL. And tire PSI plays a BIG role. Try using 32c road tires, at 70 psi.
In regards to the suspension seatpost, I have used the Cane Creek Thudbuster suspension seatpost, and the Rock Shox MTB suspension seatpost. The Cane Creek will give you 4" of travel, and you can tune the suspension using different elastomers. I found this seatpost to work very well. The Rockshox suspension seatpost works well, but it is a telescopic moving post, which moves up and down, rather than arcing backward and down, like the Cane Creek TB.

If weight, style and cost is NOT an issue: Go with the Cane Creek Thudbuster, and buy some 32c tires, (200+ TPI) and pump them to 70 psi.
(If you do that, you will one happy camper.) Although the downside, is your pedal stroke energy transfer on flat smooth sprints won't be as efficient, as opposed to a ridged post, with 19c Tufo tubular tires at 220 psi.
