Matt-
For a full description, I would recommend calling Chuck...he can tell you all about it.

I will try to sum it up..it is something new they have come up with and it is simply a solid idler wheel. It is my understanding that the wheel is machined on a lathe which enables it to be more precise in straightness....if you take it off the bow and spin it freely, it is hard to tell it is actually moving.....do the same with some other idlers and you can notice a slight wobble.


I'm sorry I can't really explain it any better...I would recommend giving Chuck a call. I believe that they are available for purchase by themselves to retrofit.
