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

Both chains come with spring clip master links

Stainless steel in wet contact with aluminium can cause faster galvanic corrosion of the aluminium than would be the case with Nickel free steels, and Zinc (galvanised) is even kinder to aluminium than plain steel.

It's only really a problem if your drive train stays wet for a long time, e.g. outdoor storage. Road salt added to the mix will make matters worse in all cases.

Guess that settles it, I'm getting the chain you recommended. You seem knowledgable, the chain is cheap, and it's rust proof. Can't really ask for more.

Cheers! You saved me around 9 quid from my original plan (the izumi)

Just confirming, this one right? http://www.wiggle.co.uk/wippermann-bmxtrack-1z1-anti-rust-single-speed-chain/
