From a distance the Triplex Profesional apes the illustrious Campagnolo Super Record. Close up it is clearly from a different planet - the Planet Cheapo. The casting lines have not been ground off, the lustreless, grey aluminium is neither well polished or well anodised, the steel parts don’t quite rust, but become horribly discoloured - and I seem to remember that the spring tended to lose the will to live after a few months.

The Profesional was the supposedly ‘high-end’ Triplex model (check out those bone coloured pulley wheels - so Campagnolo). My guess is that this example is a later version of the Profesional, with no adjustable cable outer stop and an ‘improved’ front knuckle constructed like that on the later CS models.

I dread to think which particular ‘profession’ Triplex had in mind when it named this product, but if it was that of the professional cyclist it could have only been so through an exaggerated sense of irony.
