Mine came with a bracket which goes takes up a bottle holder position; the pump is in line with the frame tube, not alongside. These are also the only extra (for a second bike, say) that I could find from Topeak.
I could design an adapter in a few minutes but getting it built is another story; I already have too many little projects so I'd prefer to buy one.
