What is Campy 8 speed cog spacing? Shimano is 3.0, Sachs/Aris
freewheels are 3.2.

I am having problems getting Sachs 5000 levers to index correctly with
an 8 speed Shimano Ultegra cassette. As Colorado Cyclist has a kit that
will put Campy spacers in a Shimano cassette, and the Sachs Ergo levers
are basically campy stuff anyway, would I solve the problem by going
with the Campy spacer conversion kit? I had the Sachs levers on my
tandem with a Sachs/Aris 8 speed freewheel and they worked fine.

Help!

Thanks.

I have done several conversions just as you suggest, respacing a Shimano
8spd cogset with Wheels Manuf. Shimano-to-Campy spacer conversion sets,
for use with their Sachs shifting systems. It works great.

I have run Sachs Ergo levers with Shimano Ultegra cassettes both 7 spd and 8spd
and also with the Wheels Manufacturing Shimano to Campy conersion kit. I found
that the straight Ultegra works OK but takes a lot of adjusting to get it right
(or close). The WM kit solves the problem and it works well. Its worth the
cost of the kit. (Also, FYI, you do not use the screews which attach the cogs
together when you install the WM kit. I was surprised by this when I first
installed the kit. ) Good luck. Jeff.

The Sachs road components are all Campy compatible (as far as I know, anyway),
and the Sachs mountain components are Shimano compatible. So if you get Campy
spacers, you should be okay.

Ready for the silly part? I was building a cross bike, and wanted to use
Sachs Ergo levers with a Sachs mountain rear derailleur, and it wouldn't
work.

The situation is a little more complicated than your first statement.
Sachs road componentry is shimano compatible in the shifters and
derailleurs. What this means is the sachs derailleurs move the chain
the same amount for a given cable pull as the shimano derailleurs. Thus
you could use shimano STI with a sachs rear derailleur or vice versa.
The ergo levers, however, pull a different amount of cable for each
click because the sachs FWs have a different spacing than shimano. The
crucial thing to match is the rear cassette/FW spacing and the shifter.

I am surprised the Sachs MTB and road stuff did not work together.

To make it even more complicated: the cog spacing on a Campi is 3.2 mm
center-to-center. For Shimano it's 3.0 mm c-t-c. For Sachs it's 3.1 mm.

So you see you cannot really mix anything, and yet it is all so close
together that you can generally get a Shimano to shift a Campi rear
wheel, a Campi to shift a Shimano rear wheel, Either to shift a Sachs.
You can mix Sachs and Shimano Ergo/STI and rear derailleurs but not
Campi and Sachs. To make it even more confusing, Ultegra and 105 is
different from DuraAce.

The best bet to guarantee everything working properly for the longest
period of time is to match components and not mix them.

It's not that complicated, because the spacer thickness is only half the
story (by the way, you got the Sachs and Campy thicknesses backwards).
Shimano spacing is 1.8mm cogs with 3.0mm spacers, 4.8mm
cog-center-to-cog-center. Sachs spacing is 1.8mm cogs with 3.2mm
spacers, 5.0mm cog-center-to-cog-center. Campy spacing is 1.9mm cogs
with 3.1mm spacers, 5.0mm cog-center-to-cog-center. Both Sachs and
Campy have the same cog spacing center-to-center (which is the dimension
that matters). Didn't I correct you on all this just recently?

Dura-Ace was different from the rest of the Shimano groups only in
shifters and the derailleurs (not the hubs or cogsets), and only for
6,7&8spd. With the 9spd groups Dura-Ace is now completely
interchangeable with Ultegra and 105.

That's what the manufacturers and dealers would like us to believe.

Nope, those are the spacer thicknesses. Everybody's standard 7-speed spacing
is 5.0 mm c-to-c, as is Campagnolo/Sachs 8-speed spacing.

Shimano 8-speed spacing is 4.8 mm c-to-c.

There's more detail on this on my Web site (didja know I have a Web site?) at:

This has not been so since the 1996 model year.

That's no fun!
