Campag mech/shifter compatibility

(expecting Pete Biggs to answer this one!)

What are the rules on campag 9 speed? Did the cable pull change at some point, making old shifters
incompatible with new mechs? How do I identify old/new stuff (veloce)?

(oh - and what's the difference between the various current rear hubs?)

cheers, clive

Yes, Cable pull and rear mech geometry changed in 2001. Some people say it doesn't matter but for
best indexing performance, don't mix old and new 9-speed levers and rear mechs.

Pre 2001 9sp: 3.20mm cable pull per click, 1.43 ratio 2001+ 9sp: 3.05, 1.50 10sp: 2.76, 1.50
(therefore 10sp mechs are compatible with new 9sp levers as far as indexing goes). There have been
no cable pull changes with 10sp.

2001+ Veloce mechs have "VELOCE" marked in large print with "Campagnolo" much smaller. Other way
around for older ones (and I don't mean capitals vs lower case).

2001+ Veloce Ergos are marked "VELOCE" large in black on the actual brake lever. Older ones are
plain. Older levers can be converted to new 9sp or 10sp (although you have to take into account that
that costs money and you get brand new springs, hoods and full cable set.with new Ergos). Some NOS
pre 2001 mechs can still be found.

There are only two major current Campag types:

1. Record/Chorus/Centaur: Cup and ball bearings, oversized aluminium axles, threadless cones with
threaded adjusting collar (adjustment possible on bike), all-replaceable parts, super light,
same design that is used in the top Campag race wheels. Centaur same as Chorus except for q/r
and requires screwdriver & fingers/spanner instead of a single allen key to adjust bearings.
Record same as Chorus except for q/r and has grease ports and titanium pawls instead of steel,
and has a 28h option.

2. Veloce/Mirage: Non-adjustable maintenance-free cartridge bearings. These are the same as each
other except Veloce shell is more polished and the (current) QR skewer nut is steel instead of
partly plastic.

Both types run smooth and are reliable in my experience so far. Both have aluminium
freewheel bodies.

See www.campagnolo.com/techinfo.php?did=c to compare part numbers.

Ta very much, that's just what I wanted to know.
