Review on 🚲 UPANBIKE Adjustable Bike Stem Riser: Enhance Comfort & Flexibility for Mountain Bikes, Road Bikes, MTB, BMX - 120 Degree, 25.4mm/31.8mm by Keegan Herbert

I wanted this UPANBIKE adjustable stem but it doesn't securely hold in the adjusted one Position. Other reviewers have commented on this, but one reviewer mentioned that it stays in place if tightened enough. Well I've tightened it up as much as I can and it still wobbles back and forth a few degrees with moderate force just for testing. There is an obvious risk that more violence or normal wear and tear will cause it to move even more and become dangerous. If the photo I've attached is correct, you can see that there is a discrepancy between the two parts that make up the main part of the bearing. I don't know if that explains his inability to stay tough. Whatever the reason, I don't want to drive with a wobbly steering column. To return.
