Review on 🚲 Coherny Lightweight Aluminum Alloy Bike Chain Tensioner - Premium Bicycle Replacement Accessories by Chris Goldsby

LOL. What a joke, so glad it was cheap! Arrived with no hardware, instructions, or pictures of intended use. As a former bike mechanic, I was completely amazed at how they planned to attach this to the bike. I even took it apart and rearranged parts to try and get it to work but then it doesn't reach the chain lol. Skip that junk and buy a Jerry SS 4 chain tensioner. It installs in seconds and has spring tension.
