I purchased and installed both products, and they were complete game changers for my ride. I bought the 27.2 x 350 mm Seatpost, and the 90 mm 6 degree stem. I installed them on my Trek Domane AL5 2025. The Seatpost was a bit longer than stock, but my fit is a fairly high seat, so there were no issues. It easily met the minimum insertion requirements. The stem was +/- 6 degree, my stock stem was +/- 7 degree so it was reasonably close. I installed it as +6 and it didn't change my ride geometry enough to be an issue. For the seatpost, a quick read of the instructions made it easy to understand how to setup the preload. I set the preload slightly soft for my weight, greased the stem, and installed it on my bike. I was careful to follow torque recommendations for tightening the stem in place. Installing the seat on the seatpost was a little bit of a challenge. the Redshift seatpost is a 2 screw mount, they are accessible, but not easily. It is a balance act to tighten both to set the correct seat angle, but with some loosening of one screw and tightening of the other, it can be accomplished. I would say that installing the seatpost took about 45 minutes to get it just how I wanted. I expect changing the preload to take me about 5 minutes, and there are clear markings in cm to aid me in installing the seat to the exact height that it was previously installed at. For the stem, a quick read of the instructions identified that I was at the very bottom of my weight group for what elastomers to install. The next combination down was a significant change. The instructions stated that I could go onto Redshift's website and view a complete list of combinations. This was slightly challenging. On the page for the stem there is no information about elastomer selection. On the support page I did find links to a video and pdf for elastomer selection. I elected to view the pdf, and printed it. Sure enough there were 2 combinations between the 2 options listed on the instructions. I selected the stiffer of the two (just below the one recommended for my wight). I mounted the stem on my bike, and mounted my handlebars. Again make note of the torque recommendations, Redshift has had them engraved on the stem, so they are hard to miss. This also took about 45 minutes. To change the elastomers, I will have to unmount my handlebars and remove a retaining plate from my stem. I do not look forward to my expected 25 minutes or so just to change elastomers. I took my bike out for a nice long ride, 20 miles, 15 MPH, and asphalt. The only downside to this trail, and the reason I bought the Redshift parts, is that there are several points where tree roots have pushed up the asphalt and created some very jarring speedbumps. Without the Redshift products, these were uncomfortable at best, and sometimes made me feel like I was on the edge of controlling my handle bars. This ride, with both installed, the seat was easy to manage, and did not hit hard. With the stem installed, I could still feel every twig and root, but it was very much dampened. You do not feel disconnected from the road, but you are very much more in control. By the end of the ride, I felt less fatigue in my arms and less soreness from the seat. While researching elastomers, I read that there is a break-in period, I would say that by the end of my 20 mile ride, the stem did offer better bump dampening than it did at the start, but I do feel that the elastomer selection I made from the support pdf was spot on. Pros: They do exactly as they advertise Clear instructions (with the exception of elastomer selection) Relatively simple installation More control Less shock Well manufactured Clean looking Cons: Neither of these items are what I would call cheap 2 bolt connection for the seat is fiddly, but manageable Elastomers, the best list is online only and not as easily found as I would have thought The listing for the stem is clear that it is a 6 degree stem, but it is hard to identify if it will install as +, - or both They only come in black, not an issue for me as I was replacing black parts with black parts, but some might like other colors Summary: If you have the money, and want a smoother ride, these are quality parts to compliment and soften your ride. Review: Instant e-bike improvement. - Just finished installing and test driving the REDSHIFT ShockStop Endurance Suspension Seatpost for my e-bike, and the difference is night and day. I inserted the inner spring because I weigh about 236 pounds and the preload is set to three and it's perfect. I'm also using the Cloud Nine saddle and the ride is just unbelievably smooth while pedaling. The price is a little steep, but I'm pretty sure this is the best money can buy. Highly recommend. ## Features - RIDE FARTHER, FASTER, AND MORE COMFORTABLY – The ShockStop bicycle endurance suspension seatpost is the perfect upgrade to your road, gravel, bikepacking, all-road, hybrid and e-bike with standard sizes to fit any brand of bike.

It includes standard and extra internal springs for increased stiffness, plus a bottom preload knob to fine-tune the exact force needed to initiate saddle movement. **Q: What kind of saddle bags can I use with the ShockStop Suspension Seatpost?** A: Standard strap bags fit easily, but rigid clamps may not. Bags on both saddle and post move as the post compresses under weight, so test your specific setup. Bags attaching to just the post or a rear rack work best with zero issues. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertised *by J***1 on June 30, 2025* This is a review of the Redshift ShockStop Stem and Seatpost.

Highly recommend. ### ⭐⭐⭐⭐⭐ Feels Great On a Hardtail Bike. *by T***R on May 12, 2025* I love it more than expected. It is like having a full suspension bike. Make sure to remove and measure your old seat post to order the right size. I bought it for a medium ebike, but the post I ordered was a little too short. However, I kept it because the size was right for my large Mt Bike. Then I bought a second one for my ebike. It comes with 2 springs and it has a load adjustment to provide the perfect feel. The second spring fits inside the first spring to provide less bounce or for heavier riders. The second spring requires installation, if you want to use it. I am 200 lbs and I tried it with one and two springs. I liked it better with one spring. The bottom of the post has the load adjustment. You turn the bottom cap one way or the other to adjust the load. It goes from 1 to 5 mm. I kept it in the middle and am very happy with how it rides. It was 20% off when I bought it. It was worth waiting for a sale because they are expensive for a seat post. Especially when you get more than one. ## Frequently Bought Together - REDSHIFT ShockStop Suspension Seatpost for Bicycles, Shock-Absorber Bike Seat Post for Road, Gravel, Hybrid, and E-Bikes - REDSHIFT ShockStop Suspension Stem for Bicycles, Shock-Absorbing Bike Handlebar Stem for Road, Gravel, Hybrid, and E-Bikes - REDSHIFT Cruise Control Drop Bar Grips for Road Bike Handlebars, fits All Drop Bar Handlebars for Road, Gravel and Fixie Bicycles, Ergonomic Comfort Cycling Accessory --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/182254414-redshift-shockstop-endurance-suspension-seatpost-for-bike](https://www.desertcart.sn/products/182254414-redshift-shockstop-endurance-suspension-seatpost-for-bike) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-28*
