(D2O) BMX Chain Tug Black (Pair)
1pair (2Pieces) BMX Chain Tug/Adjusters-10mmColour -Black The main body of these is aluminium anodised black. Lots of modern BMX riders dont need chain tensioners, mounting their wheels in the slammed position tight to the front of the dropout and adjusting tension by removing chain links (usually with half-link chains). However if you want to run your wheels further back in the dropouts and find yourself suffering from Slack Chain Syndrome, the only prescription is a chain tug. The advise is to start with a single tensioner on the drive side, and if that doesnt cure it, use one on the other side too.
The classic chain tug consists of a steel or aluminium washer with a centre hole equivalent to your axle diameter (and an outside diameter the same as that of the average peg), an end cap that fits over the back of the dropout, and a threaded bolts that connects the two. Other designs (the push type chain tug) may feature nuts designed to fit into the front of the dropout, or you can get some models that can adapt between the two mounting positions.
