This purchase has been everything I would hope. The part is performing flawlessly and has given me a much more comfortable riding experience. I installed it on my bike and haven't looked back with no problems to speak of.I will say that I gave the aluminum threads and their hardware a workout initially, as I am a bit OCD when it comes to making sure the handlebars are in the "straight" position as compared to the wheel, at least in my mind and my eyes. So, I loosened and retorqued that hardware too many times to count until I was satisfied.By installing this, it has brought the handlebar approximately 1.5" closer to me and 3.25" or so higher.I went with the 110mm neck but I could have even gone with the 140mm which probably would have put me in almost a complete upright position but I was concerned a bit about the aesthetics of it. I also like a little more balance in pressure between my butt and my wrists. I think if I was more upright, it would shift everything towards the seat and may have an effect on your butt on a long ride.I highly recommend this piece as an upgrade for your bike and can't go wrong for the price paid.This is installed on a Zeegr ebike.

With all the “accessories” on my handlebars I imagined it to be a nightmare but,it was so easy to install the quality & workmanship is a great value at this price. I now ride in total comfort with correct posture! n less than ½ an hr after delivery which was in about 24 hrs, I was adjusting my mirrors and back on the road. Once adjusted, you’re set. The performance in handling & absolute shock absorption is tremendous!!

Seems like a solid product. Have had 2 rides now and everything is still tight and solid. Hope it stays that way.

I rate this a solid 4 stars. It does the job, it was easy to install, and it came well packed and finished. My only gripe about it is that the angle adjustment hung up a bit even with the bolt loose, so it took a bit of tapping to get dialed in, but the screws fit well and it is exactly the size I needed to raise the bars to a comfortable angle for me. Get this one, it does the job.

So far this unit is working well. It feels solid and I took it apart to see if it was something I'd bet my life on and it looks good to me with the way it was manufactured to put most of your upper body weight onto a "socket or cup and other half is a male with teeth" with a bolt cinching the two halfs together.The only way that joint could fail is if the bolt snaps or strips out.The handlebar cradle is perfect.My neck is bad from a car crash do I can't keep it bent upwards, but love my bikes and so this time I went with this type of riser to help with my neck issue.Last conversation I did was replace handle bars from flat to raised and had to replace brake lines, big hassle.Th8s product isn't fixed like raised handle bars and gave me option of how high i want to raise stock bar with out changing hydraulic brake lines. Another potion I could have used and did use on another bike I had is the tube type raiser that clamps onto the fork tube and then you move your handle bar to it.I don't care for the look of those and how some of it sticks up.This is the third time I converted a bike to be more like a comfort bike would ride and I like this product design the most so far.
