Hi, I have a question for the Campagnolo experts.
I have 2 bar end shifters - the right is stamped gran sport, with an aluminium lever - the left is stamped der. centrale, with a shorter chromed lever
The bolts and springs are identical on both. I assume they are not from the same period, but would you have an idea of when the short chromed lever could have been made?
Best regards Michael
"Derag. Centrale" translates to front derailleur in English. I've only seen them in bronze. "Gran Sport first used bronze and later alloy. Derag. Centrale disappeared and Campy went to "Gran Sport" for both shifter bodies in about 1952. I've only seen GS levers in bronze in 1951 or maybe '52. Later barends were alloy. Fast-forward another year or maybe 2 and they completely quit stamping Gran Sport on the lever bodies. Scott Davis Twin Cities, Minnesota USAsdbicyclegarage.com
