from reading about 531 speedstream it seems it's quite a flexy tubeset
i did a google search for speedstream yesterday and there weren't a lot of bikes that came up
there were some nice time trial frames however
i guess a few manufacturers using this tubeset for special projects
i would hazard the speedstream is rarer or maybe the owners just don't sell them, have seen very few speedstreams but have seen quite a few AA-Supers
