That is the setback version? I asked Ergon on Twitter Jan 6 when their setback seatpost would be available, and they replied March for North America. The setback version is available at some gray market places, but not yet at even the linked German retailer.

Setback version:



Non setback:

You knew it was going to happen... eBay has several Ergon CF3 Pro Carbon Seatposts available. All are the non-setback version. The least expensive is about $198 from a seller in Kansas. Here's an eBay search for the seatpost.

I also searched for the Specialized CG-R and found just one. It was about $200 with shipping.

Looks bouncy. Let us know how it works once you have had a good test.

There does appear to be a setback version and for cheap on the site I listed above. Looks sketchy. Have the counterfeiters beat Ergon itself to market?

The Specialized CG-R we tested was a good stoker post. I just didn't like the ungainly look. Specialized stuff doesn't tend to be available online, as they cater to their LBS retailers.

Egon claims their isn't a difference in suspension travel between the setback and straight, but it sure looks like the setback would have more travel.

I believe the Ergon SB is very similar to the ST Thud Buster which has a 15 degree setback, in relation to the arch of the suspension post when making contact with bumps, etc. I would expect the Ergon straight post to be harsher. Canyon Bikes makes there Canyon VCLS Post 2.0 SB which is close to being identical to the Ergon SB seat post.
Canyon & Ergon are individually owned by two brothers, Who obviously share technology with the designs of there carbon suspension seat post.

The Ergon seatposts are likely co-branded Canyon, with different labeling. They appear identical.

True, the only problem with acquiring any product from Canyon is that they don't ship to the United States!

At Least the thudbuster let you tailor the elastomer to the rider's weight with an elastomer density swap .


I have a ST and a LT on 2 single bikes .. my choice was for my 190 pounds.

Here's a Side-by-side of the CF3 and CF3 setback.



Edit:

An 8 week review of the Ergon CF3.

Here's the CF3 Setback for half-price, free shipping from AliExpress.. Maybe its a scam, maybe its a gray-market bargain.

Rode both days this weekend with CF3 SB installed, around 40 miles each day, installed the Ergon as close as possible to what the settings were on the Thud Buster ST with a Sella Lite saddle. Took a 4mm T handle wrench, small tape measure, & a lot of patients. Settings were not even close to what the reality of how different the Ergon post ended up. First 25 miles probably made 6 stops dialing in height, forward & backward position & seat angle, the Sella seat is all about nose angle to get comfortable to support weight on sit bones at proper area of saddle. Adjusting height & fore/aft quite easy, taking seat post out every time to get proper angle correct gets old, easy adjustment thought, Plus the wife chewing on my ear that I should've just left her Thud Buster in place LOL! So after the last adjustment we didn't touch any settings until we got home & adjusted the nose height up a hair, Sunday was a group ride & no complaints on the ride, wife felt that the post performed well, gave her a bit of comfort, wasn't bouncy when we got going hard at a high cadences.

Off topic alert. Bad1, I'm looking at the ENVE clinchers with rim caliper, the double, the 12-28(?) cassette, and wondering whether its particularly flat where you ride.

It is a bit on topic, because what we most appreciated with the Specialized CG-R when we trialed it, was the stoker confidence on descents. It doesn't take much for my stoker to wig out descending to begin with, but road irregularities contribute mightily. Anything that smoothes out her experience adds confidence.

We found that last weekend while we took the Burley out (the Calfee was in the shop) with its 32 mm tires. My stoker could more easily tolerate descents. I don't know why exactly, but I think its the larger tires making the ride plusher. If that be the case, I've got to look into everything I can to smooth out the stoker experience, because her descent terror is our greatest tandem limitation.

Not flat at all We live in Bend Oregon, Cascade Mountain Range is in our back yard, 3/4k vertical climbs in a lot of different directions. We use a mid-compact 52/36 & 50/34 for steeper rides, with a 11/28 & 11/32. We have 3 different wheel set that we rotate thru depending on what we are doing.
I can truly understand your wife's concern about Self-preservation after your harrowing downhill descent without brakes functioning properly.
I believe that the CG-R would in your wife's case offer a more secure feeling than the Ergon because of the differences in functions of how each one moves under a load. Hate to say it but the Thud Buster ST is hard to beat, time will tell in our case!
As you know the Enve are fast, but also the by-product is a harsher ride which could produce that unease feeling that your going even faster than you are.
Our training wheel set is Hed Beligum C2 with some 28's Schwable 1, so smooth with the proper air pressure, my favorite pair for comfort.
I believe your on the right course with a different seat post, probably the biggest game changer would be 32mm tires, better ride, handling, etc, if that's what it takes to ease your wife's uneasiness during descents a small price to pay! Good Luck.

You also might consider doing some research on tubeless tires. I have installed a tubeless tire on the front of our Calfee and after only two fairly short rides I am VERY impressed. Smooth, comfortable and amazing feel on the corners. I have gone from 117 psi to 95 psi and the ride is excellent. No concerns about snake bite pinch punctures, no concers about blow outs! I am using the new Schwalbe One tubeless tire. The only ones that I have found currently available are the 700 X 23's. The 25's and 28's are supposed to be available soon.

Having the lowest gear compact 34t to 32t cassette still wouldn't work for us, that is like when we had 30t granny and 27t cassette and started up Redwood Gulch. At 1.2 miles, 11% grade, as high as 20%, it was desperate. In the Bay Area, especially around the South Bay, Climbs of >15% grade aren't something you have to go looking for, its more like its difficult to avoid. Then having only a 50t, it would be easy to spin out with even a tailwind. I'll cling to my triple with the same tenacity of that of Charlton Heston with his musket.

My wife's descent terror has been the biggest constant of our entire tandem career. Its not been affected too adversely with our little Montebello adventure.

According to Bike Radar, wheels make no difference in ride comfort. Its all in the tire.


We just got the Schwalbe Ones 28 mm. Maybe they might be different than the Schwalbe Ultremo's. I don't think anything larger than 28 mm will fit in our ENVE fork. It might fit in the rear, if the ENVE 65 mm 22 mm rim can take a larger tire.

I wonder what is happening with the Morgaw suspension saddle? There was PR in November, 462 funders, but crickets since then. I'd really consider adding this atop an Ergon, for belt and suspension redundancy.

So when we know we are on the way to do one of the Grand Fondo around NW with 117miles and 6500 vertical feet of climbing we go to plan B: pull out the other Macchiato with a triple to easy the pain!

Morgaw with its suspension saddle appears to be alive and kicking, it is at the Taipei bike show. They also have a seatpost, but I don't think it has any suspension features. I think this Morgaw saddle would work well with an Ergon seatpost, with two independent sources of suspension, anything that makes it past the first suspension could be dampened further by the second. Defense in depth.


TAIPEI SHOW: MORGAW SADDLES UP WITH MORE MODELS, CLEVER NEW SEATPOST DESIGN
Since we first saw the Morgaw saddle on Indiegogo, the company has been busy getting ready to ship the first designs and now also working on entirely new ones. After winning an IBDC award with the first Morgaw saddle, Martin Moravcik and Slawek Gawlik (MOR+GAW) have set their sights on MTB, Enduro and new road saddles as well as a clever seatpost design that is not only perfect for their saddles but any others as well.

Slick looking design, down side I see that will be a hurdle is that saddle selection is such a time consuming endeavor to find one that you are comfortable on, for hours at a time, possibly they could partner with different saddle makers to use their suspension system?
