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

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 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.

I really like this for city riding. I have arthritis in my wrists and this protects them from the vibration of poorly kept city roads. Not a replacement for actual front fork suspension, but way less heavy and much more stable. Travel distance is short but for my needs, perfect. Definitely add weight to your front. I like the extension it adds to my bar height, pushing it up and forward. I'm tall and this suits my posture on a large frame 29'er

Very good quality and easy to install. It is heavy, but I purchased it for the suspension.

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!

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

Purchased the KINEKT suspension stem to help with wrist - arm fatigue riding on mostly pavement and gravel. My bike does not have suspension forks so this was plan B. I'm a big guy and I'm using the softest spring which provides some vibration damping and improves comfort. I would think this suspension stem would see much greater benefit on a mountain bike or similar for off-road riding on rough terrain. If mountain biking is your thing, suspension forks will work far better having greater damping travel. But lacking suspension forks, the KINEKT is the next best option, although an inferior one. The KINEKT is a quality built mechanical suspension stem. From a value proposition, the KINEKT is a bit overpriced IMHO.

Best seat post suspension for sure
