General Information
1962 start date for the earlier version deeply fluted crankarms per Jan Heine article in Bicycle Quarterly 6/1. In the 1973 Specialties TA catalog, the Professionnel 5 Vis crankset including bottom bracket, is available in Criterium and Cyclotouriste chainring ensembles. Thus Pro(fessionnel) 5 Vis refers to the crankarms and bottom bracket, and not the chainrings. The Criterium chainrings have their small chainring(s) [double or triple] attached to a larger diameter bolt hole circle on the large chainring. The Cyclotouriste chainrings have their small chainring(s) [double or triple] attached to a small diameter bolt hole circle on the large chainring. The Professionnel chainrings [double or triple] have the largest diameter bolt hole circle, and are attached to an adapter, which attaches to the crankarm.Foil TA stickers are on the later version crankarms.
