10 speed chain?

joelsim

Not sure I really understand why a Shimano Dura Ace chain is 10 speed. Isn't a chain a chain, obviously materials differ/weight etc etc?

Confused.

It's thinner than a 9 speed, which in turn is thinner than 8 speed.

Yup... the more sprockets you have on the cassette the smaller the gaps between them are... hence you need a thinner chain
