Early Specialties TA 3 Pro Attaches Crankset: 170mm x 52/42t - Capped Pedal Holes - 116mm - English - Dust Caps (EXC+)
Early version of the 3 bolt Professional road model crankset, indicated by the presence of the closed pedal holes dating to the 1960's sometime. These are one of the nicer three pin aluminum cranks from the late 1960's and 1970's. It was the biggest direct competitor to the rare Campagnolo Gran Sport 3 arm crank. The 116mm BCD chainrings for these are fairly common, but the arms are exceedingly tough to find. Pedal threads are English/BSA, as indicated by the W stamped on the back of the arms. Includes original steel dust caps. These chainrings also fit the 3 bolt adapter for the Pro 5 Vis arms.
Excellent or better with fairly low miles. Arm ends are lightly scraped. No heel rub. Arms don't have any significant wear worth mentioning, only very minor imperfections. Clean dust caps, only light chainring wear
