Technical Q&A with Lennard Zinn – I shift, Ergo I am
Unwelcome floatDear Lennard,I have 1997 Campy chorus (9-speed) on my bike and other than the factthat I have to replace the right lever indexing spring every four years,I love it.My friend has '99 Chorus (also 9-speed) and is not as happy. It seemsthat sometime between those two years Campy changed the "balance" of thesprings in the right lever and the rear derailleur, so that instead ofclicking into one set position, the rear derailleur has about 1-2 millimetersof lateral "float" that allows you to center the chain on the selectedcog. Maybe they thought it was a good idea for folks who
