But.
If I want a 20" frame, say the T-Pro just for the sake of convenience, I phone SuperCycles up on the Monday before 12, frame's here next morning with headset, bash and BB.
If I want a 24" bike, it's either Leeson or Curtis. I phone up Clive. We talk about geometry. 1 month later I might have a frame.
It's not going to happen until they become more mainstream (at affordable prices, too), as opposed to custom orders. The Ed Tongue rode super nice from what everyone said, so I guess if Ashton could make one of those that could take a beating we'd have a winner, but until then it's just not feasible for most riders.
