Different bikes sometimes have different seatpost diameters. The ShockStop Suspension Seatpost is 27.2mm in diameter, so if your bike's seatpost is larger, you'll need a shim to adapt our seatpost to your bike's frame. Don't worry though, the shims are super-lightweight and essentially invisible once installed.
Not sure what size seatpost you have currently? There are a couple different ways to find out.
• Most seatposts have the diameter printed somewhere near the bottom of the post. You'll need to remove the seatpost from the bike frame (mark your existing seatpost height with a bit of tape before you remove it so you can replace it easily), and look for a number like 27.2, 30.9, or 31.6 (etc.). That is the diameter of the post.
• If you know the make, model, and year of your bike, you may be able to look up the seatpost diameter online. Feel free to shoot us an email at info@redshiftsports.com - we'll see if we can help out.
• Ask your local bike shop - they'll be able to accurately measure your bike's seatpost.
Non-compatible posts: Unfortunately, if your bike's seatpost is smaller than 27.2mm (for example, the 25.4mm posts found on some recent model Cannondale Synapses) our seatpost is currently not compatible with your bike. Likewise, if you have a bike with an aero/oval/non-round seatpost, or if your bike has an integrated seatmast, the seatpost is also not compatible.
350mm is our standard size, but we developed the 280mm to allow for a wider range of fits. Measure your current seatpost from the clamp collar to the saddle rail - If that distance is less than 205mm, you can use the 280mm seatpost. If not, order the 350mm size.

Bought this post because of the AWFUL Chicago streets, and I am overjoyed at it's performance. I love that it is adjustable, feels extremely well-made, and enhances the look of my e-bike. Thank you for such a thoughtful product, my butt especially thanks you. Money well spent!

This is a great addition to my gravel bike. It took a few adjustments to get the right elastomers but, it definitely smooths out the ride. Will be purchasing a set for my road bike.

This seat post is a game changer!! Absolutely love it on my gravel bike .gonna get one for my hard tail Mtb now

Love the stem!! It really takes out all the worse bumps from your ride, and on rough trails really did offer a smooth comfortable ride.
Lawrence C
I hesitated buying this stem wondering would it work, was it a waste of money but I’ve had three off road rides with my new stem and I love it. I usually get pins and needles in my hands after riding for a while but that’s gone now. Added to the comfort is the improved handling on bumpy tracks and roads. I can ride a corrugated road now without feeling like I will get shaken off the bike. Very happy.

I love my Redshift post! I recently had a lumbar contusion and the post has smoothed and cushioned the roads and trails. I’m able to stay on the bike while healing.
Ian S
After much thought I bought a red shift suspension stem and initial thoughts are that it's good, think they will become standard across all my gravel bikes.

I just finished my first ride with the Resdhift Shockstop Suspension Stem and I noticed the difference immediately. Having ridden for many years with rigid front ends (I’m 64) I now wish I had discovered this earlier in my life. The chatter that it removes from my wrists, arms and shoulders is easily noticed. This experience has been so good that now I’m considering the seatpost Redshift offers as well. The interesting thing for me is that I’ve promoted and sold these products for years based upon input from others. I just didn’t think I needed one myself. Get yourself one! You’ll never go back.

The shock absorber was easy to install and works as described cuts down on the impact. I recommend it if you're going to do gravel, writing and bumpy bumpy roads

Wow, once I got the fit dialed on this seat post I thoroughly understood why everyone was upgrading their set ups with these products. Riding a long distances is what I do for fun and for a living and this seatpost made all the difference in the world. Pay attention to the recommended Sag settings as its key to finding comfort and keeping a proper pedaling extension. 10 out of 10 would recommend.

Don’t think I can go back to riding without it
I did not know what to expect when I ordered this seatpost, but I was worried that it would be too squishy, or have too much travel, or both somehow, but I was intrigued by it and eventually ordered one. I can’t describe how happy I am with it, because it just feels so much better than riding without it. I can’t tell if or when it is moving, it just absorbs the bumps that didnt even bother me that much before I used it, but now, I cant imagine having to feel all the bumps again if I didnt have this seatpost. It really does spoil your butt & the ride overall.
United StatesLugzhurry!
Aye... it's nice to be able to ride my old mountain bike on trails without running the risk of complete castration! I'm all for being unique, but I for one am not interested in becoming a eunuch, especially involuntarily. Thanks Redshift!
United StatesFantastic, Couldn’t Spot the Scratch
Would highly recommend both this product, and buying it as a scratch and dent. Could not identify any defects at all. Really makes the ride a lot more comfortable. My hybrid bike now feels pretty “gravel” capable, even though I haven’t adjusted anything else.
United StatesTakes the Edge Off
I had the Thudbuster before and this replaced it. The Shockstop is more comfy and a little bit lighter. It’s easy to install and less bulky. The scratch and dent came through perfectly.
United StatesWorks so well I forgot about it.
I don’t think the seatpost worked… For the first 30 minutes. Then, I realized it was working SO well on the light gravel test ride that I literally was riding cush and flat-out failed to think about it. Amazing. I think I need to add a little more preload, but wow. This is a game changer for comfort.
United StatesLove at first ride
Both my sweetie and I put these seatposts on our Salsa Cutthroats in anticipation of bike packing a section of the GDMBR this fall. It was love at first ride for each of us. We had to do a little fine tuning, but it’s a breeze to dial in. Now I’m tweaking the Redshift stem; I want more squish.
