Cranks & Chainrings
|
The Specialities TA crankset with Pro 5 Vis chainrings was the system of choice for many years, due to its versatility. It could be set up as a single double, or triple, offered a huge variety of tooth combinations and crank arm lengths.
The chainrings can be assembled only one way to get the crank arm centered correctly. See below:

Above: the TA triple is fumbly to assemble with a dozen spacers between the rings but offers a wide variety of tooth-combinations. The above-pictured crank was the model available in the 1970s; compared with a modern one below, note the logo; also, the pedal bore is now a through hole, some vintage crank arms had a blind hole.
|
Above: the bolt circle has remained constant, so new chainrings fit old crank arms, and v.v.
Crank markings have been partially deciphered. 170, 175, 165 are the arm lengths in mm.

TA produced beautifully designed and machined pedals in track and road versions featuring sealed needle bearings. The pedals can be completely disassembled for cleaning and bearing replacement. Cages could be ordered of unequal height, for people with one short leg.

cleats (remember those?).
Anquetil (remember him?).
I'll bet you haven't seen cleats
in unused condition for yonks.
