For those who will be in London in the next few months this looks interesting:

Part of the exhibition is profiles of independent bike builders, including Shand. Also one that I've been reading about, Hartley Cycles. She's a jeweller/silversmith who has started building some really lovely looking bikes. Not sure how practical they will be (sterling silver details!) but they look great. I'm now trying to persuade my wife (also a silversmith) to build me a bike but she says it's not quite that simple ;-)
