External headsets? Are they all the same size?

[Eville140]

Needing a new headset for my older Santa Cruz superlight. It currently has an old aheadset that needs a bottom race. But the thing weighs a ton so I figure I'll just get something new.
Looking at cane creek 10, is ordering one simple or are there different sizes of 1 1/8" ones?

They come in different stack heights, you can mix and match so you just need to match them up.

A 1 1/8" Cane Creek 10 EC34 (external cup, 34mm) is what you need, enjoy.
