Hi, my fancy new frame just arrived and I took it to the bike shop to have the steer tube installed.

I was installing the chainset and realized I forgot something important, a chain idler.

The bike frame is similar to a Bachetta style recumbent with an 8mm tube for an idler in the center of the frame. Like this:

So I've been looking up bunch of chain idlers and it's confusing the heck out of me.

1. Smooth flanged type idler vs tooth idler. There seems to be two type of idlers in general, the metal ones with tooth and plastic ones with just flanges. I'm guessing the toothed idlers provide lower friction?

2. What kind of idler do I need to have a setup similar to the one in the picture above? I think someone described it as center axle mount. Do I need something like this(over-under idler)?
Or can I get away with this(or something similar)

Thanks gents! I think I will have some pretty photos next time.

The larger idler would be more efficient but you do need to also manage the return chain, so the bacchetta idler kit would probably work better for you.

Hey John, email Terra Cycle and ask for advice. They have kits for most models, and also various grade (price) sprocket idlers. Good luck.
