What is the inner bearing diameter of larger derailleur idlers? Is it 8mm or larger? I see they have a large bearings, then static reducers are on both sides to fit the derailleur.
I have a recumbent and it has plastic idlers to guide the long chain below the frame. The bolt through the idlers is 8mm. The stronger motor will chew up the plastic idler. I hope to fit metal idlers, something like 16T or 20T or similar.
