Which Chain? (Chains / Size / Width / Wear)

Bushed chains are less flexible from side to side, so they are worse for dérailleurs but better for singlespeed. Bushed chains should last longer, because the pin load is spread over a greater area.

Not much to choose between galvanised and stainless, since both will die from wear before the corrosion gets them. Stainless is a bit more expensive, and potentially worse for any aluminium components in wet contact with the chain, i.e. your chainring, but again it's a marginal matter. In my experience, nothing runs quieter than galvanised chain, not sure why but I hypothesise the soft Zinc absorbs vibration which stiffer Nickel coating doesn't; whatever the reason, galvanised chains are excellent for creeping up on people :-)

If you want me to tell you what ⅛" chain to run on a daily driver, it's Wippermann 1Z1. Half my bikes have that or the 3/32" equivalent 7Z1.

Hmm, was about to purchase the inox chain, but that wipperman 1z1 is much cheaper...

Do both these chains include that special link, where you can remove the link with a flat head screwdriver? That's an important factor for me as well... since I hate using chain tools more than once per chain (I always mess it up).

Why can SS damage aluminium parts when it's wet?... I imagine it's because it's harder, but why only when it's wet?
