REDSHIFT ShockStop Suspension Stem for Bicycles, Shock-Absorbing Bike Handlebar Stem for Road, Gravel, Hybrid, and E-Bikes

I am a big rider at 235 solid plus race kit I’m easily 255lbs on the bike (water, gear). I gave this a shot because I needed a longer stem and read the positive feedback from others. Purchased the 90mm length 6* degree stem and installed the 90 & 70lb rubber combo for a 70 miler gravel race. I trained hard and never used it in my training prior until the day of the race. The results surpassed my expectations as I placed 1st in my category men’s 30-39 which was competitive. Placed 7th among all males and 8th overall across all categories participating in the course (age, gender). Wow, life milestone achieved and so much more potential to improve. I was able to navigate rough terrain with much less hand/grip fatigue and most importantly a lot more bike control which produced faster and consistent speeds while others couldn’t.Now the only downside of it is the weight because it is the heaviest stem you’ll purchase unless you buy a carbon version of that is offered but I don’t think paying hundreds more is worth it over the base material version at $200+. I still rate this innovative stem 5 stars as the benefits far outweigh the weight & cost. If you need a lighter stem then do it! I’m not a pro where weight matters much as I am already a freak of a Clydesdale. I’m going to defy the smaller riders and beat them in the next race here soon. Big boy season has begun.

This is my second purchase. This stem works so well on my gravel bike I wanted one for my road bike. First, it is not like a MTB front suspension. It is a shock absorber for those small annoying bumps, chip seal, road cracks and small rocks. I get much less numbness in my hands. My ride is way more comfortable with this stem. It doesn't effect climbing at all, no bouncing.It's quality made, easy to adjust for different rider weights. The little extra weight is negligible. A little pricey but for me, oh so worth it. This product really works.

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

When I first saw the video for this, I HAD TO HAVE IT!!! I'm riding a hybrid Cannondale Bad Boy lll. It's known as a commuter, with no suspension. I ride bike paths, not roads, daily, trying to lose weight and stay in shape. With the numerous cracks and uneven payment, I thought this would be a game changer, especially when I saw the video advertising it. The bike's handlebars were flexing significantly up and down, softening the rider's ride... THATS NOT WHAT MY EXPERIENCE WAS IN THE BEGINNING!Let's be clear, and keep expectations in check. It's a bike, not a car, or a car suspension... But with that said, the stem arrives with the highest setting, and there's zero flex or cushion! Why anyone would spend so much money on this product for it to be the same as when the product is not installed and using the original OEM stem, I have no idea.It should also be noted and clear, you're GOING TO HAVE TO GO TO the manufacturer's website and watch the video on how to disassemble it to adjust and change out the "cushions", that allow a harder or softer ride. The instructions that come with it are garbage, and I have a PhD from an ivy league school.This is where it gets tricky... When you disassemble the stem, there's two little cushions, that look like oversized gummy bears. The system comes with a few of these cushions from harder to softer. You add the appropriate cushions for the type of ride you want. The problem was, even with the 2 softest "cushions", the ride wasn't even close to what was in the advertised video, or what I would consider to even justify the expence to ride quality.So, what I did was simply put in JUST ONE of the cushions (the softest), instead of two of them! It didn't say to do this, but it also didn't say not to🤣. Look, you don't want it too soft where you're bouncing, or too hard that you feel the bumps of the trail/road/surface travel up the front forks and continue abruptly through your hands and arms... Using just one cushion is what I call "GOLDILOCKS"... ITS JUST RIGHT!! I've ridden about 500 miles, and at this setting, there's been no issues.The best way to describe this product, isn't that it'll eliminate the bumps, but simply it'll smooth out your ride and make it more comfortable...To the manufacturer... If you're reading this, you have a good product, but to have a GREAT one, eliminate the cushions, and use springs. The seat post version of the suspension system IS AMAZING!! THE BEST EVER!! But it uses a spring system which is more adjustable and a softer ride.Obviously, everyone is going to have their own opinions and preference. I hope this helps you make the decision to get it or not.I highly recommend this product.
