*by R***. on July 10, 2024*

Fits beautifully

### ⭐⭐⭐⭐ Poor finish. Quality hardware. Meh.
*by T***Y on June 30, 2021*

I finally broke down and admitted that I'm getting older and need an upright posture on my road commuter. So...i bought this stem as there are few choices that are not black or some obnoxious color.The stem is adequate. It's more cheaply made than other origin8 products I have bought. The finish is horrible to boot. I'll probably learn to live with it, but it's nothing too be proud about. It's poor finish will stick out like a doe thumb in when decently appointed bikes. But, it's hard to find polished stems or steel ones. I recommend searching for vintage options or doing out big bucks for a better one-which I would have done if I could have found one!So .. I'm thankful i found it, but disappointed in it's quality. The universal sizing really amplifies the fact that you are truly strapping soft aluminum straps around your handlebar stretched tightly and held on by some quality stainless bolts.One thing to consider, you may have to increase the length of your brake cable if you are coming from a low rise stem. I now have to, though I didn't think of the possibility.
