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.
Review: Another excellent product from Redshift. - This post is awesome! I've tried more than a few others and this one is the best. Makes me more curious about their higher end model 🤔 but for now this one does the trick and it does it well. The fact that it doesn't change the distance between saddle and BB much if any is the most noticeable benefit to this design. This make it less of a distraction as it works. It just does its thing and my back appreciates it. Does it rob a miniscule amout of power transfer during a sprint, maybe. But my assumption is that if you're looking at this post you aren't that worried about such things. Check out Redshifts website measurements and recommendations and get the shortest post your frame can accept to save a bit of weight. I was able to go with the shortest of the offerings. Once again, Redshift gets the win!

The Redshift ShockStop has made my biking experience even better. This is worth every penny, my back doesn’t hurt after an aggressive ride. The ability to adjust tension has proven valuable as well. Whether on a bike trail or hopping off and on to a mountain bike trail, I have comfort and no pain. I’m glade I choose this shock over the less expensive ones. Worth every penny!
