chain size

I am not sure what size chain to buy. I see chains advertised as 6/7/8 speeds and also as 10 speed plus.

I have an old road bike. It has 2 chain rings in the front and the cassette has 8 cogs. Does this make it an 8 speed? A 16 speed? I am not really sure which size chain to buy. Thanks.

On a similar note.. does anyone know if a 9speed chain will work fine on a 6 speed drivetrain?

You need a 7 or 8 speed chain. They'll be 7.1mm wide if it's a SRAM/KMC/Taya/whatever, or 7.4mm wide if it's a Shimano.

No, it won't. It will tend to bind and slip.

Chains marked '8-speed' are designed to work with 5, 6, 7, and 8-speed cassettes/freewheels. 9-speeds are for 9-speeds. Ditto for 10spd - works on 10-speeds.
