Free floating No mounting bolts No bearings No tensioning arm No idler sprocket No lubrication Less installation time Less sprocket wear Less chain wear Less maintenance Snapidle's patented device introduces minimal wear to the chain or other driveline components. This device is protected by U.S. Patent No:4,662,862 - 4,798,562. Foreign Patents Pending. Snapidle provides a constant amount of tension to the chain drive, increasing drive life. It tensions, guides, quiets, controls and increases both the chain and the sprockets life. Unlike conventional idler sprockets, it doesn't require any ancilliary mounting devices. Further, it never requires maintenance. Constructed of UHMW, it is self lubricating and nearly silent
