steel and bb30 and 29

[Louis for real]

As the topic title suggests i have these questions.

 

1

I live right by the coast, would buying a stell frame be a unwise decision? or can you treat the frame to not rust?

 

2

And this might really be dumb so excuse me if it is...

does a BB30 bottom bracket require a speceific crank

or will my spare crank from a "normal" bb work?

 

3

were can i get hold of a complete or if possible get a build for a 29r singlespeed?

 

thanks
