Ergon Enduro grips saddles bags interbike20130918_0167

Accused of being borderline vapor-ware in the comments section of our Interbike post, Ergon has produced the goods with the posts in stock and available for purchase. As Jeff from Ergon pointed out, “The delay to the USA market is a result of legal logistics and adapting the fine print and packaging for the N. American retail level. The last we (Ergon USA) were told, we should expect a November 2013 delivery of both the setback and non-setback CF3.” And hey, it’s November 2013!

Built with an extremely intriguing design, the CF3 is essentially two pieces of carbon fiber joined by the saddle clamp that work together as a leaf spring to absorb road buzz and bumps. While the saddle moves rearward in an arc, the pivots at the head ensure the saddle stays level. The design offers a light weight (~220g), maintenance free post that is still easy to adjust. Avialable in 27.2 x 330mm  in 0 and 25mm set backs for $299.95, the seat post has a 220lb rider weight limit and is not certified for mountain bike use. Each post includes a 7x7mm rail clamp, with a 7x9mm oval rail clamp available separately.


  1. Just rode mine for the first time yesterday.

    Pros- Definitely an improvement over the rigid post. Not super effective on big bumps, but I didn’t expect it to be. Very nice on small bumps and vibration (almost non-existent). Looks great!

    Cons- It twists very easily (a little noticeable). Sitting on the nose it flexes down a bit. Sitting further back on the saddle (climbing with hands on the top of the bar) it noses up a bit. This is more noticeable but I could get used to it.

  2. This looks interesting but not so much if you can feel it tip down when on the nose. I have been tempted to try the Syntace hi flex but don’t want to feel the saddle move on these soft posts. Best posts I can find that are compliant and still solid for racing are the FSA carbon setback, Ritchey carbon setback and the zipp sercice course sl. The beauty of the Ritchey is that it’s super light as well.

  3. I think a 110lb rider would have a much different experience than a 215lb rider. Why they wouldn’t have a S,M,L option seems strange.

  4. Rad. Since I keep my bikes is a shed dubbed “the side hatch”* I approve.

    *not really, but I felt a semi-clever response was warranted.

  5. @D, Wow you’re gonna stomp on Jeff Kerkove?! I going to guess its because you think you’re faster than him or that maybe you could beat his time in the Vapor Trail. Ya I thought not! Ok ya his blogging and twittering is kinda lame, but from one Colorado Native to another don’t hate brother! (Leave that to the road bikers!) he’s actually a pretty nice guy and brings a lot to our community.

    “Whats your favorite dish, I’m not going to cook it but Ill order it from……….?”

  6. Mountain bike hardtails can increase tire width (…within limits as the frame permits)
    In addition they can buy a Thudbuster. Agree, the weight and the looks are not for everyone. Its function, however, is good.
    Beyond that – go buy a full suspension MTB.

    For road bikes the real issue is NOT ! ‘comfort’ but it is a lot more about ‘suspension’ = saving a little bit of energy by avoiding/reducing the vertical movements of center of gravity when riding over small bumps.

    Specialized cobl-gobl
    Syntace p6 hi-flex
    Ergon CF3
    (any others.?)
    ….should indeed be evaluated and compared in a scientific way wrt. energy savings.
    Hey, and if it is only a one or two percent saving. Then its just these extra two percent which you will have left at the end of a long ride.
