• Yes, I'd noticed Tony Oliver was a fan of centrepulls (and indeed of 650B wheels...). I'd not seen those Dia-Compe wing shifters before; very much like the old Suntour command shifters. Not cheap, but then neither are most of the alternatives.

    I think I'd prefer the pump in the rear triangle because it allows the bike to be shouldered more easily; helpful when rough-stuffing etc.

    It would be sensible to get a Rohloff test ride or two in to see if I like it; I suppose the easiest would be to take a trip to Thorn. For drop bars the best solution would seem to be the Gebla Rohbox.
