Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza".

I would like some feedback on getting a new post not suspension but something that have give or flex in it my bike is rigid beast using ritchey post nice but not good at removing any chatter from the road/trail.
anything out there that's not a bunch of money

Is ti post more or less flexible than carbon post?
thanks.

I have the plastic knockoff version for my mountain bike (hardtail). It works really well.

I'd imagine the real thing + the silicone anti slip pads would be even better.

I may go with Ti seat post to match bike for that.

I bought a cheap Chinese carbon post off EBay with “EC90” branding. I also have a Ritchey Superlogic. The EC90 probably weighs double the Ritchey but it also is softer riding. I would definitely go that route if you are looking for a low cost flexing post.

For context, I weigh 240.

Im really diggin my Flexlogic; I'm about 155lbs. Apparently, this is one the few posts that flex on lighter riders. It is expensive, but its a nice seatpost.

I consider myself fortunate that the Ritchey saddles fits my sit bones. The Vector wing tech really takes the Vibration out of the saddle to your butt.

This Topic, almost makes me think it is worth investing in a $200 seat post. I really do love the Specialized CGR Idea, but..... I don't need the setback. I also don't know if flex actually equates to vibration dampening. Or if flex just takes the edge of big hits.
I bought a carbon frame, even though I think 853 takes more vibration out of the ride.

I uh also invested in 700 wheels and went with Aluminum over Carbon, just for the softer ride. I can also fit 650 x 2" tires. I guess if ever comes down to a comfort thing, then I'll invest in 650 wheels and drop 2" tires on.

Am 135lb. Also have a Flexlogic with quite a bit of post showing. Does pretty well.

If you require good setback, I'd look around for a used FSA K-Force Light SB25.

Did try a ti post. Too stiff for me.

I'm just wondering how much a difference there is between something like the syntace P6 flex post and canecreek thudbuster or redshift sports shockstop seatpost. I tried the shockstop but with my bike setup the seatpost setback the seat clamp ends up way at the back of the saddles rails. I probably could make it work but I wasn't happy with it. I'm now trying out the thudbuster st. But both of those are understandably heavy. I'm wondering if the syntace p6 might be enough for me to take the edge off the gravel vibration.

Second he EC90 knockoff in carbon. Put one on a diverge aluminum frame. Paired with the brooks cambium seat, it takes most of the road chatter out of the works. For reference, I'm 150lb. I aso have the Specialized CGR on another carbon bike,ton of seat post showing, it too works well, but quite a few more $$.

20 mm is not much motion..

Or Titanium ... if it's bent a little it will flex more than if straight
and the choice of tube wall thickness can be customized for your weight..

Ti posts typically are not more comfortable than a good carbon one.

I have this EC90 seat post on both my gravel bike and mountain bike. Once you get the clamp sorted out and locked into place, they have been excellent at smoothing out the ride...oh, and I'm about 145 lbs if that matters

I think it is a POS. They advertize something like "up to 18mm" of travel, but mine doesn't move at all. It does dampen vibrations (thanks zert), and can make an aluminum bike feel more like a carbon bike in that reguard. But it doesn't have any travel.
I initially tried it on a specialized bike with a horizontal top tube, and was shocked to learn that it didn't fit me - it needs more seat post exposed that even a Thudbuster (ST)

Those are some good choices.
My thudbuster ST is amazing, and made my old stiff aluminum bike ride amazing. Still, not light, and not pretty, but pretty effective.
CGR=POS.

I bought a bike with the Ergon on it - intending to take it off and use one of the two above. But to my surprise, it is better than either of the two above. I thought my rear tire was going flat when I first used it - it was so smooth. Soaks up washboard that I just couldn't ride on 10 years ago.

I didn't think much of this test, until I ended up with some of the seat posts, and found it was spot on.
https://www.bikeradar.com/features/f...d-on-the-road/

Rather than just saying "they are all great" it gets critical and hits the nail on the head in my experience.
It looks at both deflection and vibration absorption.

If only I had this test earlier and read the part "The Specialized was the surprise backmarker of the field, beating only the Syntace when the posts were at full extension and coming in dead last when fully inserted." How true is that. POS.

The Ergon, on the other hand, is as nice as a thudbuster ST in my experience - just a lot lighter. Still that super short travel Thudbuster above looks intriguing...

I've got a Fizik R1 post (maybe out of production) that's pretty good. Best saddle clamp out there and at a decent price. Otherwise, Ritchey is going to be the best value.

I rode it over some pretty rough roads. The wall thickness of the carbon tube is about double that of the Ritchey which probably doesn’t mean much other than it is a bit more comforting that it won’t just break in half. I ride a dropper in my MTB and the notion of a breaking seatpost doesn’t scare me much anyway.

I'v bent my carbon posts a lot, but they don't care. They are designed for it. They hate point loading, but can bend a lot. I used to bend the bejeasus out of my carbon masts. That said - I can't see how a seat post can work for someone that weighs 150 lbs and 250lbs. It would seem that they need to be matched to the rider (well, Cane Creek and other allow some adjustment)
