Is it true that during the Nuovo Record era Campagnolo produced a slightly reduced diameter lower race? I heard such headsets were available for steerers that were a little over-worked for the standard 26.4. Chris King makes one now, did Campy make one then? A friend's Masi GC is crying out for one, so I would love to buy said headset if it's not a unicorn. Thanks All,Nathan CozzolinoSan Francisco, California
