SB, is a crew of graffiti writers, I suppose to be based in the Ruhr area, probably Essen. SB may be be the shortcut of STREETBOMBERS, but I have heard STAUDERBOYS or STAUDERBANDE (named after a well-known beer brand, produced in Essen) too. I don’t have hard facts due to the members of the crew. All I have, is the names of writers which are quoted due to the pieces I found over the time. And here they are, but, as always, no guarantee of completeness and no warranty of any kind!
