Review on MKS Track Chain Tensioners: Secure 10mm Axle Adjustment Solution! by Shahed Cleveland

I bet this (and I convert road to single speed as a perk and know my way around) beats them all because a) the spring notice is INSIDE the actual arm. Those outer springs always show up and you'll never find them while riding. B) There is only one screw and that is screw against screw (used by 99% of the other spanners in this category) and the screw is a typical hex case - just like your head probably. And they are never weakened by vibration. Listen: you're sticking this needle DIRECTLY onto the skewer - just take the handle off and put it back on. Destinations kind of suck, but you'll understand if I could.
