General Information
This Campagnolo crank features a 3-arm spider with cut-outs and a double chain ring arrangement.  The crank arms are chromed steel cotterless and the chainrings are a dual chainring set in alloy.

The chainring sets were available in 42/49, 42/50, 42/51, 42/52, 42/53 43/52 teeth combinations. The chainrings were riveted together and the large chainring bolted to the 116mm BCD spider. The chainring sets for later 3320/A Sport alloy cranks are bolted together.

These first appeared in the 1971 Campagnolo catalog No 16. The 1974 catalog No. 17 shows the 3320/A Sport alloy crank arms but the 1974 "Special" catalog as well as the 1975 catalog No 17a show the 3320 steel crank arms.

Bottom brackets were available in French or British thread with 112mm axle and in Italian thread with a 113mm axle.
