Redshift suspension seatpost review
 

As you may already know I am very much into finding the most effective (in terms of improving comfort) bike parts. I already tested many suspension seatpost so I had great expectations towards a seatpost made by the same company that has created a suspension stem. And after all of my testing, I can say that this seatpost really works well in terms of comfort improvement but this is still a spring suspension so you have to do a lot of fine-tuning to make it work best for you. If you are interested in more detail just read my review:

And if you have any questions just ask me. I will be doing a big suspension seatpost shootout in coming weeks so I can check/test things you want.

Cheers!

so what is the purpose of the magnetic cover? any issues attaching a saddle bag? Did you adjust the saddle height compared to regular seatpost?

No offense to anyone involved, but in my mind it's bonkers that the Redshift post (which uses two springs) costs more than a PNW Coast (which is a hydraulic dropper with air suspension.)

As a happy owner of a PNW Pine, dropper > anything else.

It protects the mechanism from debris but Redshift told me it was done just to make people sure that anything wrong will happen and you can run the post without the cover. To be honest, it looks kind of weird, especially with the rope attached and the magnetic bolt can be sometimes irritating when it attaches to the wrench while installing the saddle.

Saddlebag could be a problem because of the movement of the whole mechanism. I will ask Erik from Redshift about that to be sure. And yes, this post has around 6 mm of sag, so you should adjust the saddle height accordingly. But this is a small adjustment and to be honest you will barely feel the difference even if you don't adjust the saddle height at all.


I am very interested in finding out how PNW Coast performs. Hopefully, I will get one soon for testing!

Thanks. I have the redshift seatpost but haven’t had a chance to install it. I got a new bike and am dialing in that fit before adding the redshift seatpost. They mention somewhere on their faqs about saddlebags but nothing definitive of course.

Hi, I got the answer from Erik. The saddle that is attached only to the saddle rails will work just fine. The more traditional saddles that are mounted both on rails and seatpost should work also (they tested different examples of saddle bags and many of them performed well) but of course, they did not test everything that is available so there is no 100% guarantee that each and every saddle bag will work flawlessly with their seatpost.

Odd that you don't mention the sag in the review. Exactly the kind of real-world detail I hope to get from reviews, not as a surprise when I buy something

Fair point but to be honest I did not even think that I should mention that (maybe I do too much of testing and sometimes forget that my readers do not need to be as well informed as I am).

Of course that there will be sag in each and every suspension seatpost on the market. It has to be, there is no other way around and I don't see the problem with it. At all. But you are right, you should know before buying and installing this kind of seatpost that you have to adjust the height accordingly.

I have the RedShift stem and just installed the seatpost as well but have hardly ridden it yet.

I see you have in your wish list, more supple tires. Have you tried the Compass tires (www.renehersecycles.com/compass-tires/)? I have the Bon Jon Pass 35mm as my rear tire and the Stampede Pass 32mm as my front and love them. This is on a 2016 Diverge Pro.

I owned a Short Travel thudbuster and loved it.They are well built smooth bomb proof

Yes, I am familiar with ReneHerse tires but they are very hard to get in Europe, where I live. But for sure I want to test them and compare to my Cazadero's which I value greatly in terms of comfort.

I use both the RedShift stem and seatpost on my gravel bike and have used my Revelate Sweetroll on the front and Pika on the back. The extra weight made both more active in the rough stuff, but nothing that a few turns on the back and a stiffer elastomer in the front would not cure.

I'd love to have somebody do a direct comparison of those I had a bike fit recently and the fitter loves the thudbuster. Of course, that's what he sells but many seem to love it.

Isn't the goal of the Redshift seatpost to provide compliance on rough roads and not just the big hits? From PNW's website it looks like the Coast is designed to absorb just the bigger hits.

I have put a thousand miles on my Red Shift seatpost and stem and am very pleased with their performance. Once you get them dialed in you do not even notice them until you take a big hit. They absorb the small stuff without me even thinking about them. I have ridden asphalt, gravel and fire roads with a lot less wrist ache and seat tenderness.

I like them so much I bought another stem for my tandem and seat post for my stoker. She said the difference was astounding.

Almost full suspension, but not quite.

I'm not sure how I missed this thread, but I did my first, and so far, only, kickstarter for this seatpost. When it finally arrived, I put it on various bikes, and it has now wound up on the touring bike I have been building up. I am very pleased with its quality and performance.

This other photo made me do a double-take (my bike previously even had tires on that looked even more like the ones below):
