Why throw out a perfectly good hub every time your wheel wears out???
The TruGrit™ REUSABLE hub adapters can be used over and over again. Invest in a set one time and then all you have to do is purchase new TruGrit™ wheels when needed, saving hundreds of dollars on every wheel replacement. These adapters are required to use the TruGrit™ wheels on your existing Envirosight, IBAK, or RST transporter(s). We do offer Cues style hub adapters if needed; however, your existing Cues hubs will work with TruGrit wheels on the Cues Steerable Pipe Ranger version 1 and 2, The Pipe Ranger version 1 and 2, Compact Pipe Ranger (CPR), Lamp 2 and the wheeled version of the WTR.
