The Greenspeed Dual Idler Kit is here to eliminate those lengthy chaintubes. A T-Cycle Power and Return idler are paired using a Clamp-On Single-Sided Chain Keeper to allow the idlers to float side by side as you change gears and conquer mighty terrains. Since the chains do pass so close to the bike by the steering linkage and cruciform tube, you might need a small chaintube there to prevent contact (we recommend a pair of Floating Chaintube Holders, but only because they're super high quality and easy to install).
Note: On pre-2008 trikes, the idler shaft is 10mm. On 2008 and later trikes, the idler shaft is 8mm. Elite level idlers for 10mm shafts come with ABEC rated 10mm steel bearings. Elite level idlers for 8mm shafts come with 8mm hybrid ceramic bearings.
Have bought a few idlers over the years for several types of recumbent. The have all been fantastic!
Quality built, as usual.
I haven't yet installed the Greenspeed dual sport idler yet, because of dealing with the aftermath of a "little storm" called Ian, but as typical with TerraCycle products, it is well designed and built from quality materials. If you're looking for purpose-built upgraded replacement parts, look no further. You've just stumbled upon the motherload. They also have many more parts to customize, accessorize, and make your 'bent more comfortable, practical, and useful.

Very good service and excellent quality product. It came from the US to Australia much quicker than I expected. Very pleased, thank you
Excellent product, just didn't work well on my greenspeed GT 20. Not T-Cycles fault
