Sachs Maillard Clusters LY model details?

I have a couple of Sachs Maillard 8 speed clusters. One is marked LY92 and the other is LY97...

Does anyone have a definite list of which model numbers are Shimano or Campagnolo compatible?

Given the age of these, i haven't found a list which confirms if either is shimano or campagnolo. I don't have calipers so can't accurately measure the cog spacing.

My understanding is that these Sachs clusters were made for the Sachs ARIS system of indexing.

As clusters they are superb, one of the best tooth designs. I've used several different Sachs on my friction-shift bikes. To use them in a modern indexing system, I don't know.

The 6's are difficult, in that with a conventional (70s era) freewheel hub, axles are sometimes not strong enough to be used at 130 mm OLD. Originally they were designed for 120 mm OLD.

Thanks for the reply. I was running the LY97 on an old Zipp 950 disc for TT's using Shimano 8 speed indexed bar end shifters and it worked okay. Only asking as I am not using these clusters anymore and was planning to sell the LY92 when i was asked if it is Shimano or Campag compatible.

I lined the LY92 and LY97 up and eyeballed they look like a match, but I've just read it suggested that only LY96 up were Shimano compatible and those in number below Campagnolo compatible. Unfortunately I dont have digital calipers to measure the spacing to confirm.

Compare the color of the spacers (if they are clean enough to see) Shimano is one color and Campagnolo are a different color. The spacers determined the indexing compatibility, not the model number. The bodies of the freewheels are the same.

I want to say that Brown is Shimano and Gray is Campagnolo--- but only IIRC! So proceed cautiously.

Interesting. The LY92 is NOS I'd saved as a back up so is spotless; this has definitely brown spacers. The used LY97 looks like brown spacers too and is the one that I used with the old SIS bar end shifters...

Just found the following reference on https://groups.google.com/forum/#!to...ch/Y1bX1eEYTFI

"Sachs makes two different spacings in their freewheels, namely spacing for Shimano indexed systems and Campy indexed systems. Shimano compatible freewheels have black spacers, Campy has brown spacers. A Shimano/Sachs freewheel will not index properly on 8spd Campy and vice-versa."

Looks like mine are both Campag compatible - which is odd as I was running the Ly97 as SIS shimano!

The older campy 8 speed spaced cassettes freewheels would work OK with sis in some cases. But for the most part the campy 8 speed stuff wouldn't work with a SIS freewheel cassetes.

I'm going to say I remember the Campagnolo version having BLACK spacers, Shimano was brown. This for 8s freewheels at least.

I don't use these freewheels myself, both because I don't normally use 8s freewheel hubs and because Sachs/Maillard/Aris freewheels transmit more-limited power, more roughly, during shifts toward larger cogs.
...That compared to Uniglide or Suntour freewheels in my experience...

So we are 50/50 if brown spacers denote Shimano...
