Box Two Chain Tensioners let you dial in your chain tension so it's just right.

Two mounting holes provide room for ample adjustment on most frames.

Single-bolt design does not mar dropouts or paint finish on your frame.

When used properly, Box Two Chain Tensioners help protect frame dropouts and keep your rear wheels locked in place where they should be.

Available in anodized colors.
