I have a pair of old logo Cinelli Giro d'Italia bars that are 42cm measured
outside to outside on my 1976 Kessels Main D'Or, but I still find them nar
row. When I built up my 1978 Merckx (also by Kessels), I opted for a 3tt
t cockpit, and found a great deal on ebay Germany for a 44cm set of superle
ggero bars in the Eddy Merckx bend (less than $50 shipped). They match p
erfectly with the period correct 3ttt SL seat, but they are also the most c
omfortable vintage bars I've ever ridden. Nice width and great hand posi
tions.
