I think an IRO has a higher chance of being stolen than a Bob Jackson. Kind of like how the most stolen car is a Toyota Corolla. Everyone has one, and they're easy to sell. You can't walk out of a store, see someone riding a black Mark V with IRO hubs/Deep V's and yell "HEY! THAT'S MY BIKE!!!"

Bob Jackson has a long lead time (8+ weeks usually) BTW, even for their "off the shelf" frames. Obviously not as long as a lot of custom stuff, but still much longer then I'd want to be out of the saddle.
