Inexing conversion - more Campy questions

Quoted message said:

If I get a used wheelset with a Campy Record 10 speed hub, do i need to
use the Record cassette or can I use a cheaper one. Will the cheaper
cassettes affect (i.e. wear) the aluminum freewheel body on a Record
hub?.

You can use any cassette. I don't think that the hub body is
different on Centaur, Chorus or Record.

I've forgotten the advertised tooth max for a Racing-T rear
derailleur. I used one on my tandem, 52/42/28 and a 13/30 cassette
w/o problem. If your inner cog is 36, you should have zero problem
with chain drag on the front derailleur.

I'm no expert but I recall my Racing T's came with literature
suggesting they were made work with up to a 28 rear cog. Isn't that
the largest that Campy offers as well?

I'm pretty sure you could set it up to work fine w/ a 30 if you adjust
it and the chain length carefully.

I have a Campy Centaur 9 speed with a Shimano style wheel and casedtte,
and a 30 tooth as the rear largest. I put it togeather from two
differnet casettes, according to Sheldon's advice. He sells a "century
special" that seems to work with most rear ders, and has a 30 as the
largest.

All the best,
Larry

From the catalogues:

2000 Racing T: max 28, capacity 37

2001 Racing T: max 29, capacity 35

To use a wider gear range than "allowed", have the chain as short as
possible for the big-big and avoid the small-small gears.

No, even the cheapest Campag 10-speed freewheel bodies are aluminium now,
with the same spline pattern as Record's. Use any model of cassette you
like.

you can use a Campag 28(9s) or Campag 29(10s) w/o problem. Remember
that '10s' and 13-29 was around before long cage RDs from Campag.

Veloce cogset, either 9s or 10s will work fine and dandy. Cogs wear the
same as those above it, just the addition of aluminum carriers and ti
cogs affect the weight a smidge and make them much more expensive. Like
chains, 'least expensive and compatible' is the way to go.

On my long cage 9sp Veloce, I have an 11-32 SRAM cassette with
conversion spacers, and a 52-42-30 Veloce crank. The RD clears the 32t
cog just fine, but I need a 116 link chain (SRAMs come standard at 114,
Shimanos are 116) and have a little droop in the 30-11 combo, which
should never be used anyway. My setup has 43t of difference, so I guess
that would give a total capacity of a hair under that - 40 or 41 teeth
of wrap?

The Racing T rear derailleur was a medium cage. Back then Campagnolo
had short cage and medium cage. They now make all of their rear
derailleurs in short, medium, and long. The long is very long. I
tried a medium cage with a 52-42-24 rings and 13-28 cassette. The
medium cage did not wrap up enough chain for me when using the inner
ring with the smallest 4 or 5 cogs. Long cage works on all cogs with a
24 inner ring.

My short, medium, and long cage rear derailleurs all clear a 28 tooth
rear cog. Medium and long clear a 29 tooth rear cog. Never tried the
short cage with the 29 cog.

we have this on our Waterford demo bike, double full sized crank and it
works just fine and dandy..large-large to small-small.

Anybody have the cage lengths for what Campy considers long and medium
these days?

If I go with Campy wheels I'll use the 13-29 10 speed, and if I go with
Shimano wheels I'll use (probably) the Sheldon custom "Century"
pattern, 13-30. With a 52 T large chainwheel, I don't need any gears
taller than 104 inches.

How do I tell what year my rear derailleur is? I don't see any patent
marks. The cranks don't have any diamond numbers on the arms, like
Nuovo Record and Super Record. The chainwheels do have some markings,
and diamond C's. I assume my front der, rear der, and crankset are the
same year, since the Ebay seller said they were take-offs from same new
bike. Not reliable, but the best info I have.

Campagnolo USA has it listed.

55 mm bolt to bolt on short cage.
72.5 mm bolt to bolt on medium cage.
89 mm bolt to bolt on long cage.

If you don't have wheels now, then get Campagnolo wheels and use
Campagnolo 9 or 10 speed cassettes. No issues or worries about whether
you need to match 10 speed Ergo shifters to 9 speed Shimano or use a J
Tek adaptor thing. Which cassette you run, 9 or 10, would depend on
what your Ergo shifters are. Yes you can change Ergo levers from 1999
onwards between 9 and 10 speed. But that would run at least $50 in
parts. Maybe more. Just use the cassette that matches the Ergo you
have.

As for going with Mr. Brown's 13-30 9 speed custom cassette. You can
cheaply build your own. Just buy Shimano HG70 or HG50 cassettes. They
have loose cogs and come in sizes such as 12-25 and 14-23 or so. Mix
and match with ubiquitous loose cog 11-32 and 11-34 cassettes. The
11-34 has a 30 tooth cog.

Doesn't make lots of difference, sort of. Pre 2001 rear derailleurs
have a different swing than 2001 and beyond rear derailleurs. You can
use Pre and Post 2001 Ergo shifters and rear derailleurs together. But
I have found shifting suffers, a little but noticeable, when they are
not matched. Pre 2001 rear derailleurs and pre 2001 Ergo. 2001 and
after Ergo and 2001 and after rear derailleurs. Since you mentioned a
Racing T rear derailleur, I would guess you have pre 2001. And
presumably your eBay bike is old so it will have pre 2001 Ergo. And
everything will work just fine.

I don't see any patent

Crankset and front derailleur year won't have any affect on your
drivetrain.

No real markings as to date..Just some time with a stack of catalogs
from Campagnolo, and differences in graphics, can give a clue.
