KINEKT Suspension Stem for Bicycle Handlebar - Adjustable Shock Absorption for Road, Gravel, and E-Bikes for Increased Shoulder and Neck Comfort

The damping system is excellent; it absorbs all the impact on the hands—even the strongest shocks. It is a heavy component, which added quite a few grams to my carbon bike, but it was well worth it. I've had it for a few years now, and it hasn't needed any maintenance so far. It's very durable.

I've owned one of these Kinekt spring stems now for about a year, and put a couple thousand miles on it. I love these! I'm about 155 lb, so I had to use the lightest spring they provide, but it's about right. On most paved road bumps I hit now, it rides roughly in the center of its travel - and occasionally bottoms out on the really severe bumps on our lousy Michigan roads. That's about what I'd expect, for suspension tuning for any such bike part. My only (tiny) issue with it is, it seems a little-overdesigned (too heavy) for 'bike weight snobs'. That's ok, they can continue to get their teeth rattled by the rock-hard ride of their bikes :) ...Actually my next step with this will be to drill some lightening holes here and there on the assembly, away from the corners where stress is concentrated of course. Overall, a very worthy and helpful upgrade... even at it's significant price. One last thing - I did order (and return for refund), the similar RedShift polymer suspension stem this month. It just didn't measure up to the Kinekt's pleasant, wide and linear deflection. The RedShift's polymer 'springs' are way too stiff and nonlinear in action. Plus I kind of like the open, techy look of the Kinekt stem. Nice! UPDATE June 2024 - I now have these on three of my bikes (a carbon road bike and two of my e-bikes)... still very happy with them! A few here have been troubled by the small travel of the unit. I do agree it doesn't move a lot; at most there's maybe an inch of travel. But it's constrained by the stringent bending and twist requirements in a steering stem. It simply MUST be super stiff and strong for such loads. Also - IMHO, you get most of the utility from the first 10-15mm of travel in these; they crucially take the 'edge' off the initial jab or jerk of a sudden bump. I've now put thousands of miles on these, with no problems whatsoever. It's the mark of a great design and product, that now I barely notice them - nor the hundreds of jolts my wrists and shoulders used to absorb on each ride.

I'm really happy with the KINEKT Suspension Stem. Works great,but after installing it on my bike, I changed the spring to the lightest one, and when I did I lost the little lock screw for the pin. I've contacted Cirrus through emails and phone messages for the last three months to get a replacement screw, but they haven't bothered getting back to me at all.

You will see the exact same pics on the review for the seatpost, these things are awesome! The stem does a fantastic job of taking the sharp edge off of the bumpy sections of the bike trails, it greatly reduces fatigue and the soreness us older folks feel after a long ride. I have put about 45 miles on the stem and it works flawlessly. There is no side to side flex when you jump out of the saddle and crank on it, it is STOUT! I will say this, and it's not a knock in any way, it just is what it is: this component is not light, if you are what we called a "spoke licker" back in the day, this isn't for you. I have the 90mm, 7 degree, and it weighs in at a stout 470g. Not as heavy as a suspension fork, or anywhere near as expensive. I STRONGLY recommend this thing, it is awesome! Now go read my review on the seatpost!

I never write reviews but I thought this one deserved it. My wife has severe arthritis in her wrists and hands she always complained when she hits bumps how bad it made her hands hurt. So I did a little researching and I found this stem and purchased it and I put it on her electric bike it’s night and day it made the ride so much smoother and now her hands don’t hurt when she hits bumps. It is well worth the money if your bike doesn’t have front shocks. Very easy to install.

This stem provided two things for me. It got me more upright over my old stem with the 100mm 30 degree rise , it gives me significant suspension to smooth out the rough stuff and yes I have it paired with my cross country suspension fork. Together It's much better !! I feel it was worth the money.

Easy install and feels SO good when riding. Although pricey ?

The Kinekt Suspension Stem is excellent. I have a road bike with a flat handlebar. I had a tough case of tennis elbow from riding too much last year, and I was looking for something to lessen the stress my arms take when I saw this thing. I use the heaviest spring, and I took out the little stop between the two end stems to get maximum travel. When I ride along and look down at the stem, it is in CONSTANT motion. This is motion that would otherwise be transmitted directly to my hands, wrists, arms, elbows, and shoulders. This stem absorbs the impacts and greatly lessens the overall stress that I would otherwise take during a ride. This thing is truly revolutionary and worth every penny and gram it costs. In addition to doing a great job, it appears to be solidly built. I don’t expect any issues from it.

ロードバイクのロングライド用に購入しました。２年くらい使用していますが、手の負担が軽減しました。それなりに重量があるので、レース志向の方やヒルクライムメインの方は、「必要ない」と思います。悪路・ロングライドの用途なら、強い味方になってくれます。

Super durchdacht und in der Wirkung zwar nicht mit einer Federgabel zu vergleichen, aber kein Vergleich zu ohne. 100EUR hätte ich mir noch gefallen lassen, 200 sind zuviel. Ich werde es behalten, die Wirkung ist deutlich spürbar.

I was skeptical at first and also concerned by possible lateral and undesired movements and play. Also doubius about the actual device ability to absorb any shock. But I was wrong: this thing is amazing. The added confort is real and it completely changes the ride, in a positive way. What I found interesting is that with the original spring and my load, the handlebar is somehow suspended and floating, meaning that shocks are absorded in both direction (upward and downward). This means that when the front wheel goes suddenly down (due to a hole or a step) the shock is partially absorbed before being transfered to the arms. Same as it happens with a suspended fork.

Habe den gefederten Vorbau 50 (Grad) von KINEKT für mein e:sy Kompaktfahrrad gekauft, da dieses keine Gabelfederung hat. Bin nun bis jetzt ca. 200 km damit gefahren und sehr zufrieden. Die Vibrationen sind merklich abgefedert worden. Fahre entspannter und angenehmer.

An meinem Reiserad habe ich auf eine Vorderradfederung verzichtet, damit ich vorne eine Gepäckträger anbringen konnte. Auf z.B. Feldwegen schlug dann aber quasi jeder Kieselstein durch. Dieser gefederte Vorbau hält diese vielen kleinen Stösse ab, die sonst von Händen, Armen und Schultern abgefangen werden. Auf langen Touren fand ich das sehr entlastend. Zuerst war es gewöhnungsbedürftig, dass der Lenker sich etwas auf- und abbewegt, doch die Lenkpräzision leidet nicht. Beim Einbau muss man etwas aufpassen, dass der Vorbau beim Federn nicht an andere Teile anschlägt. Ausserdem ist der Tausch der Federn ziemlich fummelig - immerhin sind überhaupt Federn für verschiedene Belastungen dabei. Nach ca. 4000 km kann ich keinen Verschleiss feststellen. Ein gutes Teil, wenn auch teuer.
