Please help!

To be fair, neither an Aerospoke nor a Brooklyn Machine Works track frame are things that a middle-of-the-road bike shop owner regularly sells, isn't it?

I don't think that the chap that runs the bike shop on Roman Road (my LBS) has heard of these either.

I wasn't implying that they would stock either but could get them in or know of someone who might stock that caliber of frame/components... the point was they had never heard of them!
