UPANBIKE Road Mountain Bike Bicycle Stem Riser Adapter 1 1/8" φ22.2mm 25.4mm*150mm

This stem adapter did the job! I was looking for a stem that would allow me to put a "threadless stem" in the place of my quill stem for my Kent KZR mountain bike. It worked & I was able to put a 1 1/8 stem that would hold a fat handlebar or a 31.8. Bike looks great! It made an aesthetic difference!

I heard this one ( or maybe another) got recalled, but it didn't break on me...i don't know what those dudes were doing, maybe they were jumping from 50 meter cliffs 🤦🏻

This worked great to switch my bike over from threaded to non-threaded

Works perfectly fine, only subtracted a star because it’s ugly. Definitely better to pair this with a modern stem than trying to find an old style stem in the size you need.

Good

Bought this for a drift trike project my son and I were working on. He cut up an old style BMX bike for the front wheel assembly. Wanted to use an updated stem and handlebar set up. This allowed us to use the fork tube he welded into his frame. Easy install. Seems well made. Would buy again.

This adapter works well, but has one major flaw: It is not possible to easily tighten the adapter after installing a star nut. I installed the adapter in a steerer tube that was a couple of inches too short. I used Locktite on the threads to ensure it did not loosen, but after 10 minutes of riding, the adapter started to slip. I could not easily tighten the adapter because the installed star nut prevented getting a wrench to the adapter to tighten it. This was a known risk when I assembled this, but I am disappointed that it did not hold. I will get a fork with a longer steerer tube that does not need an adapter.

Have a Kent Genesis Saber 700c with 80's/90's technology. Use this UPANBIKE Riser adapter to replace the most uncomfortable one-piece handlebar and stem and added a Meroca SS01 Suspension stem and a Salsa Cowbell Handlebar. Highly recommend this UPANDBIKE Riser Adapter.
