Which Chain For 10 Speed Drive And 8 Speed Cassette

Gonna put Campagnolo 10 speed front and rear derailleurs as well as a
10 speed crankset on a bike I'm building up. I want to use an 8 speed
cassette in conjunction with down tube shifters. The cassette will be
made from a loose cog Campagnolo Ultra drive 9 speed cassette and
Campy's 9 to 8 speed conversion spacer Kit 3. This way the cassette
will fit any current 9-10 speed Campy rear hub wheels that I choose to
use, and it also should allow for somewhat practical shifting with
down tube shifters as opposed to a 9 or 10 speed cassette. My
question is: what chains will work with this set up and which will
work best?

Friction shifters? any chain...index, 8s shifters? 8s chain, like a
Sram PC-48.

For reducing a 10 speed rd to 8 speed, Branford Bike suggests using
wider 9 speed rd pulleys ($20) and 9 speed chain for 9 speed or 8
speed.

I would agree with this. When I got my 10-speed Centaur RD, I was
running 9-speed parts otherwise. My SRAM PC-971 chain made horrific
noise going through the pulleys. I switched to a Wipperman 1008, and
the noise went away. It shifted well on 9-speed cogs until I got my 10-
speed shifters and cassette.

If I was doing a project as described, and encountered the same noise,
I'd switch to 9-speed pulley bushings to space out the cage.

Branford suggests a lot of things that aren't necessary. We use 10s RD
as replacement Rds for all Campag systems, including early gen 8s..w/o
mucking with pulleys or using a chain that is not speced for 8s
spacing...but 9s chains are more expensive, so no wonder.

Branford has a SRAM 89R for $30. $10 more for a better fit?
Never heard much about 10 speed, since Sheldon's sites don't mention
much about 10 speeds in articles.
So just assumed the 9 to 10 speed was a major crossing line. And
thought Campy
suggested similar parts but you are the expert. It just sounded like
sound advice to me.

Those are expensive parts to ground down prematurely.

Does that shop still exist?

Dear John,

Wow! That's great news! Not only are they reopening, they're reopening
HERE! (In Seattle, near me. Life is good.)

Thanks for the advice.
