Excellent upgrade part
The SE bike tensioner works flawlessly and keeps my chain perfectly aligned. Easy to install and adjust, itโs a small upgrade that makes a big difference. I consider it an absolute necessity for any SE bike setup

Work great for my tall unicycle chain.
Needed new chain tensioners for my tall unicycle. Was going to pay $38 from unicycle.com when I was checking out, shipping was going to be another 20 bucks. That got me looking at other options. These work great! Much cheaper. East to put in and adjust. A win win win (unless youโre Unicycle.com.).

Very handy
I like these for micro chain adjustments and centering the rear wheel on all of my BMX bikes. I builds 20โ BMX and this is an option that I highly recommend. They add some style too.

Glad I Went with These.
These are simple and quality. If they work on your bike frame, you will be quite happy. I don't even like tensioners but like a tighter chain, so one on my drive side lets me put tension perfectly. It holds up well, looks good, and is simple. I would buy again.

Donโt buy from China !
It didnโt come from China ๐จ๐ณ. Thatโs why quality is 10 times better! If you like quality purchases check the vendor if it comes from China expect low quality and tough returns!!!!

Fixes the issue of my rear wheel from sliding loose in the dropouts
I bought the aluminum chain tensioner for my 7 speed bicycle with belt drive. It fits the 3/8" (10mm) axel; and to mount it in place, I had to shave down the tip of the faceplate of the chain tensioner (shown in the second photo), which was fairly easy to do with a steel file. So far so good. The bike rides smoother and a bit faster with a tighter belt drive, and corrected the issue of my rear wheel from sliding loose in the dropouts when peddling.
