Suspension Stem, 7 Degree 45mm Height Rise Adjustable Bicycle Handlebar Stem for Shoulder Comfort, Shock-Absorbing Short Handlebar Riser for Mountain Road Bike MTB BMX Black 90mm

I purchased the suspension stem with apprehension, not expecting such positive results. I have a gravel bike with 45mm tires and I ride mainly rails-to-trails gravel type mountain roads that are long and chunky at times. Pedaling upgrade isn't so much a vibration issue but the long and faster downgrades would turn my hands numb and every time I'd have to stop until the feeling came back. Riding the same trails with the Gaderth has relieved may hands and shoulders of any discomfort whatsoever. I tested 2 springs before choosing the perfect tension. Also, my stock stem measured 100mm vs 90mm so not a big difference, but turns out I like 90mm better. It's a well thought out rugged design and easy to install. Perhaps I could have spent 3X as much to get the same results.

My bike does not have any suspension and very narrow tires, so this makes a huge difference in the shock tranmitted into my shoulders when riding on moderate terrain (city commuting - pot holes, curbs, etc). For 1/3 the cost of the one made by Kenekt that looks to be basically the same design, you can't beat it. Decent quality even though it is looks like it was probably made in China. The red spring worked best for me.

I love my Heybike Sola electric bike but it came with no shock absorbers at all. I quicky learned where the smoothest greenway paths were and could manage with the few bumps. I eventually learned of a seat post with a built-in spring. That worked wonders but was only half the battle. Today I installed my new Meroca SS01 suspension stem and I'm amazed. I left the spring that it came shipped with in it and after installing it and an extension to allow me to sit straighter in the saddle, I hit the hard paths (well, hard for me) and was pleasantly surprised. It made the 75 minute outing much easier on me. After about 50 minutes I started wondering if I should try a softer spring to see if I couldn't overcome some of the rebound effect of the device topping-out after a bump. Suddenly, it came to me that there is a tension control on top of the device. I stopped and made a small tweak of about 1 1/2 turns counter clockwise. Holy cow! I found the sweet spot. I continued riding over gravel and bumps because I couldn't believe the difference it made. It almost made the bumps and gravel disappear. I'm writing this after only one ride, but that's just how happy I am with the purchase. It appears very well made and rugged. The tiny amount of instructions don't even mention this adjustment, but it really is a game changer. Also, the tiny instruction pamphlet suffers from the same sort of translation problem that the Amazon description has. It can be overcome with a little imagination. Still, if you've never installed something like this before, find a couple of videos on Youtube on the topic because it can be a little tricky if the screws are not tightened in the proper order. In addition, I loosened the spring tension on the seat post for even more comfort.One thing I forgot to mention is that as soon as I loosened the tension on the stem device, the bike suddenly seemed much easier to control over gravel. My confidence with handling the bike was vastly improved. Honestly, one minute I couldn't wait to get off of the rocky surface, and the next I'm riding in disbelief at the difference. Having this opens up new possibilities of places I can now ride comfortably.

Building a flat bar gravel bike from an XC hard tail. I am using the stiffest spring on a rigid fork. It lessens the chatter nicely. On a hard hit there is a clunk when the device returns that will take some getting used to. It’s also a little over a pound which is still lighter than the 100mm fork I swapped out. I like the way the bar moves vertically instead of pivoting in comparison to other systems.

I was looking to install shock absorbing forks on my fat tire but the price and hassle of installation kept me from doing it. I ran across a review of shock absorbing stems that was positive on there abilities so I decided to try a less expensive one. This works wonderfully in absorbing the shock of mountain biking with my fat tire and I have done many rocky and rooty trails with it and my wrists are so grateful. I settled on the second stiffist spring as the stiffist was almost like not having any shock absorbance.

I screwed around with the Springs a little bit just to see what worked the best, and I think the second to the hardest worked the best for me at just under 200 lb on a surly disc trucker with high-rise downhill bars. The comparable product to some of the others I've seen is pretty decent.Only three stairs due to the weight of the product, it is still the bicycle industry after all.

I was considering putting a shock absorbing front fork on my bike to cushion my wrists and elbows. Then I came across this. I was dubious at first fearing the steering would suffer but after testing a couple of the supplied springs I found everything worked perfectly. My wrists, elbows and even shoulders are much more comfortable. The solid build makes me confident it's safe. Highly recommended.

It’s a gimmick! It provides very little comfort. I had to use the lightest spring to get some movements. In general, I would just save up and buy a better fork shocks instead.
