## Overview

The REDSHIFT ShockStop Suspension Stem is a high-performance bike handlebar stem engineered to reduce up to 70% of road vibrations and bumps through 20mm of finely tuned suspension travel. Featuring five swappable elastomers, it offers customizable damping to suit road, gravel, hybrid, and e-bike riders seeking enhanced comfort without sacrificing steering precision. Crafted from forged aluminum, it maintains rigidity for aggressive riding while dramatically reducing hand and arm fatigue. Compatible with standard 28.6mm steerer tubes and 31.8mm handlebars, this maintenance-free stem transforms your ride into a smoother, more controlled experience.

## Description

The ShockStop stem does what gloves and extra bar tape can't: it isolates your upper body from the imperfections of the road, letting you ride further, faster, and more comfortably. The patent-pending ShockStop is designed from the ground up specifically for road and hybrid bikes - the suspension travel, weight, feel, and aesthetics are finely tuned to perfectly complement your bike and the roads you ride on.ShockStop dramatically improves the quality of your ride, without compromising steering responsiveness or detracting from the aesthetic of the bike. The subtle PurePivot design allows the front end of the bike to move up and down over bumps in the road while your hands follow a smoother path, cushioned by the elastomers inside the stem.ShockStop’s forged aluminum components are extremely torsionally rigid, so climbing and sprinting feel completely natural. The limited travel provides just enough cushioning, without affecting the geometry or handling of your bike.So what does it feel like? In a word: smooth. Road buzz is almost completely eliminated and impacts from bumps and cracks are dramatically muted.ShockStop comes with 5 different Ride-Tuned elastomers so you can precisely adjust the feel. Racers, triathletes, and competitive riders can choose firmer settings to retain a more traditional front-end feel, while commuters, fitness enthusiasts, and endurance riders can dial in a softer feel to maximize comfort.CompatibilityShockStop will fit most road, hybrid, and triathlon bikes. If your bike has a threadless stem, then it's an easy swap. If you're bike has a quill stem you will also need a separate quill stem adapter.Steerer Tube (Fork) Diameter: 28.6mmHandlebar Clamp Diameter: 31.8mmNote: Handlebars that are swept back towards the rider will limit the effectiveness of the suspension. We do not recommend using ShockStop with handlebars where the hand position (grip) is more than 1" (25mm) behind the handlebar clamp.

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.

## 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

**Q: frist of all will this fit a domane alr 31.8 handle bars also do not understand the measurements 6×100 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.

### ⭐⭐⭐⭐⭐ Smooths out the chop
*by R***R on November 2, 2025*

I own both the 30 and 6 degree stems which I use on my gravel bike. One for more upright pleasure riding and the other for more speed rides. The suspension works very well on choppy gravel roads and helps reduce the jolts and chatter. Not 100 percent better but significantly better. The price is high but it's a good solutions for zero suspension bikes like mine. I also own the ShockStop Suspension Seatpost which is a big game changer.
