My 2008 Ice Trice “S” has always had a sagging return side chain that almost touched the ground as it got close to the long cage on the rear 20” wheel. Also, the chain tube on the power side always bothered me. After trying a variety of fixes that didn’t quite get it done, I mounted the Dual Idler with an over/under keeper on one of the T-Cycle clamps, locating it just under my seat. Bingo! No chain tubes, good tension and enough side-to-side movement to keep the chain and rear gears happy. The power side goes under the idler, and the return side goes over it. The kit is mounted just low enough to keep the deflection on the power side productive, but I still have plenty of ground clearance under it. This idler kit, paired with one I bought from Terra Cycle 12 years ago(!) for the front location work very well together- smooth and quiet cruising and shifting, and the feeling that what I put into pedaling is transferred to the rear wheel without a lot of power loss.
Thanks to the crew at T-Cycle (especially Aaron) for helping me get back on my trusty trike!
