But then, we're talking about a folding bike used to commute/tour, not riding in the Tour de France.
Besides, while shifting down fast is important, in practice, it matters a lot less if shifting up takes ~a second.
Next time I have a chance, I'll experiment with the Litepro B clamp and yet another derailleur, making sure to match the number of speeds for the derailleur and the crankset.
