Great to hear. I'm uploading the 2024 updates today!

I lived in a rural area with atrocious chip and seal roads. Sus-stem, best road bike add-on ever. Where they also shine is old school seemed concrete roads, separated asphalt or packed dirt roads with potholes.

I've had both on different gravel bikes, a Vecnum suspension stem and a Rockshox Rudy suspension fork. For me, the suspension stem feels way better than no suspension, but I always wanted more out of it. While the fork feels like it's enough suspension. But I don't do these epic multi day rides where maintainability is a factor, and ride a lot of singletrail on my gravel bike, so depending on the use case and priorities the optimal suspension choice will be different for different people.

One thing to remember is the Kinekt has optional elastomers you put inside the spring. The kinekt doesn't bottom out using this set-up.

I would very much like to see the testing protocole - first, sensor placement (are they tied to the body parts, or rigidly fixed where the body parts are), but most importantly postprocessing of frequency response graph into a scoring system.

Thankyou for this video. I have been using the Redshift on my gravel bike for some time, it works great. Absorbs a lot of vibrations - reducing fatigue and I feel noticeably less shaken out after rides than before. I can confirm that it really works, but never saw any numbers and science behind it. Now it is clear, not just how, but why it works.

This video was the very reason I bought a Meroca 4-point suspension stem. While I don't go off-road on my touring bike, I do travel on roads with lots of potholes and uneven pavements. I'd say that this is cheaper to have this replaced than maintaining a suspension fork in the long run.

On road bikes, maybe. On true MTB? No. Never. You're comparing 100mm+ of travel to a suspension stem ffs.

One qualitative benefit of suspension stems to me is that they make the ride at the front end of the bike feel… luxurious. Feeling the stem moving and absorbing small chatter is oddly satisfying in an ASMR type of way

Super helpful video Alee! Thanks for this valuable research and the excellent presentation!

Thank you for another useful and very informative video. I had a Redshift stem on my gravel bike with a mustache style flat bar and it was useless because of the very problem you describe with single pivot designs. I think I'll give the multi-pivot Freeqence stem a go.

I bought the FreeQUENCE stem for my trip to Kenya and the Migration Gravel Race. It saved my arms and hands during four days of 8+ hrs on the harshest roads I've ever encountered. Other riders had deep blisters on their hands after two stages. Meanwhile, I felt pretty fresh each day since I wasn't getting jack hammered. I also use a Cane Creek eSilk seatpost to keep my lower back from locking up after 5+ hours of riding dirt. My front tire has significantly better grip on rough surfaces and my eyes no longer bounce around in their sockets. Before purchasing, my biggest concern was how it felt while standing since I am out of the saddle a lot. Yet, I never notice the stem moving while standing. Now I'll never build up a gravel bike without one.

Great vid! I see 3 types of bikes where you CAN'T use a suspension stem: 1. Some folding bikes that don't have a stem, but rather a vertical handlepost that the bars attach to. There is no place to put a regular stem. 2. Bikes with very short stems, as you pointed out. Though apparently no-one has done it yet, it is possible to make a suspension stem, at least a single pivot one, where the pivot is BEHIND the steerer tube, and the stem is split and fits around the steerer. That will enable very short stems, if not quite as short as rigid ones can be. (The Specialized Future Shock could also be made with a very short stem.) 3. Recumbent bikes. Technically, some use standard stems and could fit a suspended one, but it would be pointless as the bars only carry the weight of your arms, not your body. Here the suspension must be in the fork and/or frame.

Great video. Very comprehensive and informative, as always. I'm beginning to wonder whether my computer is bugged because I've spent the last week investigating suspension stems for a possible purchase and WHAM! This comes along and gives me all the answers. Thank you!

Thank you for your reviews, they are always very interesting and well made. Keep going! A big thank you from southern Chile

Great video as ever. Like how you explain everything very precise and laid back. Regarding that supsension stems. I have a Specialized Diverge EVO and although I know that the Future Shock is no comparison to a suspension fork this bike makes me ride really gnarly trails. I love it. The Diverge EVO is a great flat bar gravel bike.

I have a repetitive strain injury from too much keyboarding. The dealer that sold me a TranzX suspension stem 30+ years ago saved me. I wouldn't be able to ride (literally) without it, other than on a recumbent. For a while I could not turn up alternatives and TranzX had stopped making them. I was seriously worried about the day when my existing gear gives out. That day is nearly upon me and I'm delighted to know there are so many alternatives. I've gotten two new bikes over the years and each time had to take the stem to a blacksmith shop to modify it to fit.

Thank You for making this video! It’s was very insightful. And you answered all of the questions I had from your previous video! I truly appreciate the time, energy, and effort you put into making these videos. PS. I bought a Kinekt stem thru you, thanks

I used to have a Haro bike in the 90s with elastomer stem suspension. I liked it.

Redshift user here. Not a gimmick. Bleddy marvellous, tunes out high frequency vibes and takes the thud out of rough tracks.

Superb video. The best explanation and analysis I have seen on this subject. Critically, the differences in single and multi-pivot suitability by style of handlebar was new to me, and is so important. I now know I should look for a multi-pivot stem given I have sweep-back bar and a more upright tour bike sitting position. Thanks!

Yes, redshift stem plus seatpost is a game changer on my touring bike. Soooo smoth ride!

I used one for several years. One drawback was diving when braking. Despite this I greatly preferred the bike with it than without.

After going to a titanium framed bike last year, I've really gotten into comfort over absolute performance. Been thinking of going with the Redshift stem, but my reservation is that I've been hit by a car twice, and I use a GoPro mounted on a K-Edge Garmi to record every ride. Even with image stablization I would imagine it would create a nausia inducing image. Can't think of a better place to mount it on the bike, fork crown would be an idea location, but can't figure out a mount.

Super informative thank you. Been thinking about a stem for my touring bike to replace the fixed 80mm. Looks like the Redshift is the one I'll go for.

Been using the original Redshift stem since it came out.

That is on a drop bar bike though where there's a lot of leverage as my hands (and weight) are cantilevered out a fair distance, but I never tried it on on my bike with swept back bars for the reasons that you've mentioned. My hands are pretty much in-line with the steerer, so because there's no leverage. Perhaps leverage isn't the right word, but ya get me!

Do you run it with a positive or negative rise? (12:32)

The Vecnum freeQENCE Suspension Stem sounds like a winner. My bike has the Cirrus Cycles Kinekt Suspension. It appears the Vecnum has a similar execution, with slight improvements to design and materials. I'm happy with my stem and have no complaints. For those interested in my pursuit of comfort and handling improvements... I bought a ridged Class 3 e-bike, designed for urban use. The ride was extra harsh. I live in a big city with plenty of poorly maintained roads. After several longer rides, I knew that I had to make some changes. I detailed all of my improvements to illustrate that no single improvement does it all. It would be great if that was the case. The first improvement was going from a 28mm to a 38mm tire. A suspension seat post was the next step. Followed by replacing my stock stem with the Kinekt Suspension. Finally, I replaced my stock flat handlebars with the Spike 800 Vibrocore bars with a 75mm rise. Everyone of these additions contributed to my bike eventually becoming far more comfortable as well as adding confidence in handling.

I’ve been using the Redshift Shockstop suspension stem pro for a number of years now and find it the best bang for your buck as no servicing required, dampens most vibrations and doesn’t weigh that much more than a regular rigid stem, compared to a suspension fork, gaining all the benefits

The parallelogram systems formally have merits, however, are too heavy for a sports bike.

@oreocarlton3343

Cann Headshok is a fork suspension just with shorter travel

Hi Alee. I have a question/comment. When describing the Redshift, you said you “didn’t like the negative rise setup because the direction of the force coming from the ground up is different from the stem’s movement” (which is downward). But isn’t it that the upward direction of force is transmitted through the head tube and therefore, because of the pivot joint, the counter action is downward at the handlebar mount? Isn’t the negative setup supposed to be the correct reaction to cancel out the upward force? In other words, if the head tube goes up, the handlebar must go down to have any dampening effect.

Totally sold on the Specialized Future Shock. I don't think I would own another gravel bike with a suspension stem of some sort.

Been thinking of adding the Kinekt to pair with my now 6 year old seat post. On that, I've had 2 maintenance issues, both solvable ... add loktite to the adjustment allen bolts... otherwise, they will tend to come loose. The only major issue happened in Peru at the beginning (of course) of a 20 day tour. The weak-link passive, plastic component (hard to describe) failed, broke, and the seat 'fell' backwards to a 60 degree or so, with a rearward sloping angle (so nose up, and unridable). I figured it out eventually in a very sketchy neighborhood and solved the issue with zip ties, but the shock absorbing feature was gone. Luckily, they sell replacements and the post is as good as new now ... other than those 2 issues, I''d definitely recomend given the thousands of miles of very, very rough travel the bike has been over. So I think I'll but the stem... right now!

I just built my 2020 Santa Cruz Chameleon into a rigid skinny-fat 29er, with 3.0 front and 2.5 rear. I would absolutely LOVE a suspension stem for it (I already have one on my flat bar gravel bike, which I converted to that spec thanks to this channel's videos, and it is fantastic), but the suspension stems available are at least 80mm long, and the bike uses a 50mm stem and has a 35mm diameter bar. The alternative is obviously the Flexx enduro bar, which operates on a very similar principle, but I feel like I won't like the rise in the use I'm putting it to (I have a 35mm riser on my e-bike), and I think the positioning of the elastomers will make doing jumps and things much more awkward. On the other hand, the reach on the Chameleon is a pretty short, even shorter now that it no longer flexes in the front with the fork, and so I could easily add another 30mm for a stem, and I do actually have a spare 31.8mm bar (my old e-bike bar), so maybe I will try it after all.

my bike has an 80mm stock stem and slightly swept back flat bars. (Its a commuter style ebike).the Redshift is the only stem that comes in 80mm but they don't work on swept back bars. You said the Kinect works well on bikes that are more upright with swept back bars. The shortest Kinect stem is 90mm. Would increasing to 90mm be that much of a difference on my bike? Or I could get different bars...

My hypothesis: Suspension stems bobbing up and down is not issue (in terms of robbing power transfer to wheels) not because the travel is low in comparison to forks, but rather because it's disconnected from the legs to the ground: legs->feet->pedal->frame->fork->ground. I.e. if you use a fork suspension, the fork is between the legs and the ground: legs->feet->pedal->frame->fork->wheel/tire->ground. It may require more upper body energy to stabilize yourself when sprinting with a suspension stem that has a too low spring rate. Disclaimer: I speak from personal experience with suspension forks/stems and applying some limited physics knowledge.

I would love to use one of these, but my frame is rather large for me and i needed to put the smallest stem possible for it to fit. 😅

Brilliant.

I agree that the suspension stem can move and shown to be shock absorbing. But is it really desirable? If the handlebar is moving relative to the saddle, that instability is transferred to hands, arms and spine, making your upper body bounce. A fatter tire offers compliance, but relative to the saddle, keeps the handlebar position unchanged. I've ridden with a 90's elastomeric insert suspension stem, but think a steel fork with more rake or a softer front tire is better. Even so, I appreciate that suspension stems do offer some high frequency vibration damping.

Sagan ripping on the future shock 😅❤

I wish the specialized future shock was on the other side of the head tube like in BMC Urs suspension.

Does a suspension stem relieve pressure on a carbon steerer tube ? Allowing a higher tube .

Does the ground force direction and the stem movement matter being in a slightly different direction matter that much? An actual question!

For almost any bike. I need a riser bar (bmx) and super short stem to achive a comfortable reach and i ride mostly hands free to protect my upper body. My canyon leaf spring carbon seatpost has a good enough suspension and hope to find a riser bar that has a similar suspension. Do ordinary riser bars without cross-bars have suspension? What material might be best?

while bmx bars and altbars often provide comfort through better hand positions the addition of crossbars and also the use of steel tubing can often lead to a harsh ride in other ways. Composite bars engineered with flex in mind do very well here and also some thinner ti bars offer a nice amount of cush. Am alternative for you could be one of these multi pivot suspension stems paired with a steerer extender and very rearward bars.

I personally consider Suspension Stems as great upgrade for rigid bikes. I still use a "Girvin Flexstem" (quill) from the early 90s in my everyday (Steel) Bike. It works perfectly, of course with new Elastomere Elements from Time to Time (means "long Time", about five years). It is the same Elastomere as Skateboards have, which are available in different grades of stiffness. But yes, of course are new Types of Multi Pivot Suspensions Stems much better than my Girvin Flexstem. On the other Hand I did not feel the need for a new Stem ... I would need an Adapter (for Quill-Mounting) and it is quite expensive ...

I’ve never done any maintenance on any stem over the last 7-8 years of testing.

A WORD OF CAUTION: Please give your brain some time (about two weeks of riding) to adjust to a moving stem/handlebar or it can easily result in a crash. Why..? When riding a bike your body and your brain grew up depending on three fixed points... Feet/pedals, butt/saddle, hands/H-bars. So if you install a flexing stem suddenly your brain is given a vast variety of new and confusing inputs, so it has to instantly send a response to all your muscles to keep the bike safely on course. So obviously the mind is now confronted and confused with a new learning curve. Kind of learning how to drive a stick shift car. Eventually the brain will learn how to shift the car without even thinking. SO TAKE YOUR TIME, about two weeks of careful riding will do it, to avoid crashing.

the TLDW question is: are these redundant if you have a sus fork?

Pff, too late. I already bought and installed the anti-shocks. They have some effect as I can see them move while cycling but can't really compare to others. I also got suspension seat posts (eesilk) at the same time which really were a nice comfort boost. Edit: so I remember reading a study that had the Transx at half the dampening ability of a Redshift shockstop so I looked it up and realised it's the same paper you quote in this video. I know 20% reduction is much less than 45% reduction (rounding to the nearest 5%), but the shockstop is 168g heavier, has a minimum length of 90mm (compared to 80 with transX), and is over twice the price. I was also concerned about how much bob would be present on the redshift and eesilk if standing while peddling and so I'd end up going with a tough elastomer in which case the benefits in vibration reduction would be reduced. Anyway, long story short, I ended up going with the transX for these reasons . . . though if I knew the eesilk could provide 2x the vibration dampening ability while also being just as comfortable standing or going up-hill I would probably have gone with that.

I wonder if this technology cans disable death wobbles in motorcycles.

I watch these videos even though never use anything like this on my emtbs mtb but yeah it's just because like everything bike it's good watch to see some interesting crazy ideas ugly as they are they all have a purpose for one job somewhere! these might suit the commuter ebikes better that come with poor suspension forks or nothing atoll for the Infamous UK pot holes and cracked up roads! I'd feel unsafe standing up on the bike and really pushing it up hill with these things bouncing to much incase the went to low and made the rear of the bike to light and end up face planted into the front tyre or road haha

Wish I had this on my BMX my wrists would've love me now I'm prone to numb hands while riding 😢

A downside when comparing to a suspension fork. The suspension stem does not protect the lower steering head bearing from destruction.

Why don't you just use a fox 32 suspension? It has a lockout function.

i've removed my suspension seatpost again and i think the same would happen to suspension stems. when there is too much vibration you just loosen your grip or lift a bit out of the saddle. that much more effectively reduces the load on your body. when you have those gizmos, you don't loosen your grip, and even though the magnitude might be reduced, it's still more than when you let go a bit. so in the end the thing that's supposed to help actually makes things worse.

Nothing new here - I toured decades ago on a Cannondale T1000 with a Softride stem. Loved it then, love my Redshift stem (and seatpost) on my e-bike now.

Made them in the 90's.

if you need suspension that badly, get a suspension fork, much more rugged and imho far safer

The kinekt stem is built like a tank and comes with all sorts of spring strengths. It even has an optional added elastomer so your spring will never bottom out. My little carbon folder doesn't have any suspension fork options.

Suspension doesn't eat pedal energy. It maybe feels like it would, but technically it doesn't.
