I just bought this for my cheap gravel bike. Makes a big approvement to the jarring, really smooths out the bumpy surfaces. Definately feels different at first but I'm used to it now, don't really feel it. It does add some weight to the front, the bike has at tendency to fall when on the stand. I tried 3 springs, with the blue spring it's compressed about 2/3 when I'm leaning on the handles bars with my 85kgs, about a 1/4 compressed with the red spring. The green spring is strong enough to be fully extended when leaning on the handle bars but still surprisingly effective. I'm using the red at this point. Highly recommend as a cheap suspension stem option
In my gravel bike, when I'm working, it makes a knocking sound at its maximum deflections. There are no rubber bumpers to muffle the metal-on-metal sounds. I need to make some rubber bumpers: one at the bottom and two at the top on the sides. Other than that, this suspension stem is great. It really suppresses unevenness very well. I bought this product based on your video, among other things :)
How is it going on for yours? Initially had used the blue spring. It functions well in terms of reducing handlebars jarring. However, I was annoyed by the knocking sound, and the loss of some steering control. After a number of experiments, I came to this solution as the best for me: - cover the red spring with heat-shrink tube, overlapping the springs top and bottom, coat it with grease - insert two rubber washers directly under the top hex key mounting plate and tighten only halfway to reduce pre-tension - lower the handlebars 2 - 3 cm to put more weight onto the front This reduced the knocking by 80% under maintaining full handlebar control and relevant jarring reduction. This product is a winner for its price, but best would be some silicon dampener at the deflection end.
Absolutely amazing product and I fully recommend it. I am using it on my EMTB in combination with Rockshox Judy and this is solving all kind of bumps you can imagine. It is very good for high frequency bumps
To reduce the snap-back impact, add a plumbing rubber washer below the screw which locks in the desired colour spring. That makes a significant improvement on my bicycle.
I see K, but no B. I mean, that seems to be only a spring, and a spring has not vibration disipation as it only works as a reaction force. Do you know if im the internals has any kind of elastomer??
Just bought one for my gravel bike. Do you feel it is safe on a carbon steerer. Since my bike is carbon and this is pretty hefty. Just wondering what you think Thanks for posting.
I envy you! You apparently live where roads are made of glass, out my way, they're full of differential cracks, potholes, frost separation cracks. This suspension stem is a godsend!
surely this defeats the whole point of the product.its for non suspension bikes to absorb shocks into the hands.surely the suspension forks already do this.

Could u send video on your rubber bump and grease Lube applied to this stem

These reduce the high frequency chatter, that forks cannot react to. They help with arm fatigue.
And when it snaps to its normal position, is it not soft, more like a BANG!?
Here I see problems.
(Additional to the spring quality topic)
Springs are cheap
To reduce the snap-back impact, add a plumbing rubber washer below the screw which locks in the desired colour spring. That makes a significant improvement on my bicycle.
Have you continued using this product, the quality is good, have the springs not lost their rigidity? Greetings.
It is still going good
The springs seem to set a little but then it stays that way.
I see K, but no B. I mean, that seems to be only a spring, and a spring has not vibration disipation as it only works as a reaction force. Do you know if im the internals has any kind of elastomer??
no, it doesn't. But it still reduces jarring and shatter.
Is it able to use it upside down? since i always use stem in minus 7 degrees

Around 4nm for carbon
I've got one of these on a Surly Bridge Club and really like it on a bit of rocky or gravel stuff but don't see much point on the road

Can the stem be locked?
I did order also base on your review. Did you find any replacement of spare springs?
There is nothing really wrong with the springs. It needs some sort of dampener for the deflection end, but for its price its the best buy.
what spring do you like the most?
Number 3
in the end you showed nothing about how it works
Suspension stem on a bike with suspension fork ? You will not test it properly
@@michalmordarski7175 make your own video then
@BicycleForHealth I've two air forks. With lock. Even locked out have some travel
that is for rigid fork only
its for whatever you can put it on its not exclusive to RB's or GB's
Why are you using a suspension stem with a suspension fork? Too much will affect your handling. Well whatever works for you 🤔
Its pointless to put it with a suspension fork, you just adding 1lb to your bike.
surely this defeats the whole point of the product.its for non suspension bikes to absorb shocks into the hands.surely the suspension forks already do this.
it makes the riding experience very plush. Like a suspension seat post in a full suspension bike
