MUQZISingle Speed Chain Tensioner, Bike Chain Tensioner Adjuster MTB Adjustable Tension Adjustment for Road Bicycle Cycling

I used this tensioner to turn my MTB into a one speed road bike! You can adjust and slide it to any sprocket that you wanna use. You don’t have to remove the shram and get a one speed adapter to make it work! The cogs I picked were a perfect alignment. All I did was take about 4 links out of the chain to give it plenty tension. Don’t know the longevity of the spring tensioner but so far so good . If it breaks I will let you know.

Solid design and the range is great..

I saw the price of this and thought I'll probably be sending this back because it a cheap peice garbage but I was totally wrong and pleasantly surprised. It's quality made and functions as it should. It also doesn't bad either. I put this on a single speed mtb build and love it.

I found this idler wheel and tensioner to be ver easy to install and it is securely fastened but could use a little thread locker to keep it tight while in use.
