This is the Elite Series Power side idler only (no kit). Beautifully machined side aluminum side plates and now a pair of "Ceramic Bearings" (8mm only) available, otherwise our long used ABEC 7 bearings which are machined to the tightest tolerances of any steel bearing readily available. Titaniuum cogs are standard on this idler since aluminum is now available on our 14/15 tooth Sport Series Idlers. This is the top of the line idler that you can get anywhere and outshines the competition by such a wide distance that the only idler even close to being as good is our own Sport idler, so we are really only competing with ourselves for idler quality. We have been making and incrimentally upgrading it for years now. These idlers have proven themselves durable and functional while being the nicest idlers in the world cosmetically. We take great pride in the Elite idlers and have great confidence in their function as proven by thousands sold and giving day to day improvements in performance for so many makes and models of recumbents that have this upgraded idler.
