REDSHIFT Standard Stem PRO Stem City Seatpost Endurance Seatpost PRO Endurance Seatpost Review: Impressive. Works better than I expected - After reading some of the negative reviews and comments I wasn't sure what to expect. This is definitely working for me on my new Cannondale Topstone gravel bike. My commute to work is 8 miles (one way) and the bike path and roads are not even. Especially roots pushing up the pavement is common on the bike path. It is rather painful when going 20mph and hitting them unexpectedly (e.g., in the dark). I am also going on an unpaved trail through the woods. The before and after are astonishing to the point that I am still impressed even after riding this for a couple days now. The movement of the handlebar is substantial. I didn't expect that. The quality and craftsmanship of the stem are excellent. The installation was easy (unless you are as stupid as I am and remove the original stem with the magnetic brackets falling down to the bottom of the fork inside the carbon fiber tube - duh). Overall, a much smoother experience now and a lot less impact on my hands and arms. So much more fun! One little side effect that is somewhat annoying is that my rearview mirror is shaking quite a bit due to the dampening effect :). I followed the weight table, and it seems to be just right. I wouldn't want it any softer or harder at the moment. Once the weather gets better, I'll try out a mountain bike trail with it. I am very impressed Review: Works as advertised - This is a review of the Redshift ShockStop Stem and Seatpost. 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. ## Features - UP TO 70% BUMP AND VIBRATION DAMPENING: Say goodbye to sore hands, wrists, and upper body, and enjoy increased control, more comfort, and a super smooth ride while the ShockStop Stem reduces the effects of impacts and vibrations - REDUCE FATIGUE AND INCREASE EFFICIENCY: Stop wasting energy absorbing bumps and vibrations with your body and let the stem dampen the terrain - 20MM OF DAMPED SUSPENSION TRAVEL: Just the right amount of vertical compliance without sacrificing any stability or compromising steering, plus in the lateral direction the stem is as rigid as a standard stem allowing you to sprint or climb out of the saddle with confidence - TUNABLE SUSPENSION: The 5 swappable elastomers let you dial in the perfect stiffness and feel - COMPATIBILITY: Easy to install and maintenance free, the ShockStop stem fits bikes with standard 1- β…› inch (28.6mm) steerer tubes (where the stem attaches to the bike frame) and fits 31.8mm handlebars (shims available separately for smaller handlebar diameters); this stem is NOT COMPATIBLE with oversized steerer tubes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08LLD1HJT | | Additional Features | Aluminum Frame | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #75,466 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #64 in Bike Stems | | Bike Type | Hybrid Bike, Road Bike, Triathlon Bike | | Brand | REDSHIFT | | Brand Name | REDSHIFT | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 1,422 Reviews | | Frame Material | Aluminum | | Frame Material Type | Aluminum | | Included Components | 5 Ride-Tuned elastomers | | Is Assembly Required | No | | Manufacturer | Redshift Sports | | Model Name | Stem | | Model Number | 975b2d19-477d-4d98-9e7c-3f1431278cc4 | | Number of Handles | 1 | | Power Source | Pedal power | | Size | Length: 80mm | | Style Name | Stem Angle: 6 Degree | | Suspension Type | Front, Rigid | | Theme | Bicycle Suspension | | UPC | 736313570052 | | Unit Count | 1.0 Count | | Warranty Type | Limited | ## Product Details - **Age Range (Description):** Adult - **Bike Type:** Hybrid Bike, Road Bike, Triathlon Bike - **Brand:** REDSHIFT - **Color:** Black - **Frame Material:** Aluminum - **Included Components:** 5 Ride-Tuned elastomers - **Size:** Length: 80mm - **Special Feature:** Aluminum Frame - **Suspension Type:** Front, Rigid - **Theme:** Bicycle Suspension ## Images ![REDSHIFT ShockStop Stem 20mm of tunable front-end suspension - Image 1](https://m.media-amazon.com/images/I/716VJ8ZL9yL.jpg) ![REDSHIFT ShockStop Stem 20mm of tunable front-end suspension - Image 2](https://m.media-amazon.com/images/I/71cRZ49G2jL.jpg) ![REDSHIFT ShockStop Stem 20mm of tunable front-end suspension - Image 3](https://m.media-amazon.com/images/I/71blrgafnXS.jpg) ![REDSHIFT ShockStop Stem 20mm of tunable front-end suspension - Image 4](https://m.media-amazon.com/images/I/71GT87elwCL.jpg) ![REDSHIFT ShockStop Stem 20mm of tunable front-end suspension - Image 5](https://m.media-amazon.com/images/I/612ZFqElMdL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: What do the different sizes mean, like 90mm? Is it a measurement on the bike I need to take? How do I know which size to order for my bike?** A: It is the length of the stem, center to center. Measure your current stem from center of steering tube to center of (diameter of) handlebar. The longer the stem, the longer the reach. A small change can make a big difference in comfort level. Measure carefully. This is a very nice suspension stem. It takes vibration away from hands. **Q: Is there a sku for ordering one with shims on amazon? my handlebars are 1" (25.4mm)** A: Shims from Amazon https://www.amazon.com/MUQZI-Handlebar-Aluminum-Bicycle-Conversion/dp/B09BQB9PC1/ref=pd_bxgy_sccl_1/144-7925088-0949638?pd_rd_w=x1LpD&content-id=amzn1.sym.26a5c67f-1a30-486b-bb90-b523ad38d5a0&pf_rd_p=26a5c67f-1a30-486b-bb90-b523ad38d5a0&pf_rd_r=WVEC5RMXZ7MATFBA233V&pd_rd_wg=HciQV&pd_rd_r=d2e06161-e947-4344-b136-a5d96558c876&pd_rd_i=B09BQB9PC1&psc=1 **Q: frist of all will this fit a domane alr 31.8 handle bars also do not understand the measurements 6Γ—100 mm** A: Yes, it will fit. I just installed mine on my Domane SL5. 6 = is the angle of the stem, either 6 degrees rise or 6 degrees lower depending on the way it's installed. 100 = is the length of the stem, from center of steerer tube to center of handlebars. **Q: will this fit my 3 week old Aventon Soltera step though 7 speed ? Thank you** A: It fits all standard mtb/road/gravel stems, have no idea what size stem your bikes stem takes, sorry. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive.

I bought the shortest version of this stem this time. I also have a 100mm x 35Β° rise on another build. The shorter version (55mm) works very well when on the hoods but as expected does not do as much when on the flats or drops due to the pivot point on the stem and the backsweep of the bars (Redshift kitchen sink) but it does eliminate some vibration. The real sweet spot is on the hoods which is where I am 80% of the time. I haven't messed with the elastomers yet. The ones that came stock feel pretty good to me for now. Looking forward to getting on some rough gravel/washboard to really feel the difference. Like most things bike, it's kind of expensive. But worth it imo. ## Frequently Bought Together - REDSHIFT ShockStop Suspension Stem for Bicycles, Shock-Absorbing Bike Handlebar Stem for Road, Gravel, Hybrid, and E-Bikes - REDSHIFT ShockStop Suspension Seatpost for Bicycles, Shock-Absorber Bike Seat Post 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/241858374-redshift-shockstop-stem-20mm-of-tunable-front-end-suspension](https://www.desertcart.tn/products/241858374-redshift-shockstop-stem-20mm-of-tunable-front-end-suspension) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
