The Bent Crank: Chronology of an Idea by Harvey Sachs

Each year, the bicycle industry produces dramatic and radical advances in technology. One of the most startling of these was the P.M.P. "bent" crank, which outdid even the Gear-Tel for originality. Harvey Sachs, best known for his active leadership in East Coast tandem events, predicts what the future holds for P.M.P. in the following special report:

1981: P.M.P., a small Italian firm, bursts on the scene with the revolutionary "bent"crank, featuring a 90-degree bend in the crank arm. The "L-shaped design increases the pedal's propulsion power and lessens energy dispersion on the downstroke, " according to the manufacturer's literature.

1981: The British magazine Cycling issues a set of P.M.P. cranks to an unnamed first category Surrey roadman for road testing. "Whatever the theories, in practice our roadman tester felt the P.M.P. cranks offered an advantage and surely that is the true criterion," Cycling reported. The roadman himself said, "At low pedaling speeds, dead center seemed to be removed. "

1982: P.M.P. cranks are the talk of the New York trade show. Not many orders, but lots of talk ...

Zum Vergrößern anklicken....

Der Text spricht von ähnlichen Vorzügen wie bei nicht-runden Kettenblättern.:rolleyes: Also schon ohne Polchlopek-
 
The British Best All-Rounder (BBAR) competition, organised by Cycling Time Trials, is an annual British cycle-racing competition. It ranks riders by their average speeds in individual time trials, over 50 and 100 miles (160 km) and 12 hours. Between 1980 and 1989 Ian Cammish won the title a record 9 times.
