Timing Chain vs. Gears vs. ?Roller

He's talking about a "fake" chain that looks like a double roller chain but does not have true "roller" links.

True "roller" chain actually has individual rolling sleeves on every single pin that rotate.

The cheaper chains look like a "roller" chain but have solid pins, and don't wear as long.

Puzackly. Thanks. I missed his question. You also need to be careful which true rollers you get. I've seen some with some real cheap lookin sleeves as rollers. Some of them flat out SUCK. Most of the time with timing sets, you really do get more for your money. The more expensive sete are generally the better ones.
