I visited London last week and made a bee-line to visit BLB to get some inspiration and buy some bits. I was pointed in the direction of an American (i think) female who told me she didn't have any Sugino 75 chainrings in 48T as the American Importer's don't send that size which I thought was quite odd. Sacked the rest of my want-list as she then offered me a 46T. Bought a 48 of Hubjub this week, arrived today... sweet! And that will probably be my only dealings with BLB.
