Made from high quality delrin, this durable idler has an o-ring which provides great performance and a 6mm bearing. It is also handy in other return side applications too. For example, older Vision bikes used something close to this for return chain management and these idlers can be used as a replacement.
When switching from the original Volae front idler to the new Delrin idler, you will need a Volae Front Idler Conversion Kit. It may also work on old Vision Recumbents, but will probably require hardware adaptation.
