Over Under Idler Pulley
Worked just fine even in a hybrid application.

Best there is
I installed this dual idler on my custom recumbent bike. It works like a charm , smooth and silent. You can't find a better dual idler anywhere. I highly recommend it.

Don't bother looking elsewhere
I've been working on bikes since the early sixties when me and my Dad would fix up my little Sears 20 inch coaster brake bike after a hard days thrashing. Countless bikes bought sold ridden since then, always fiddling around or upgrading something. I am the consummate tinkerer. In those years I've become and un become a Campy snob, always looking for the best. Recently I bought this TerraTrike, which is merciful on my knees. Naturally I couldn’t resist....the drivetrain was noisy. So I replaced the rear idler(s). What a difference! Well-engineered and fabricated AMERICAN parts. Who woulda thunk? Thank you!

For Barcroft Virginia
I replace the chewed up idler on my old Barcroft Virginia with this Haluzak Kit. It works better than the original.
