Sachs Maillard 6 Speed Freewheel

I removed this very nice early 1980’s Sachs Maillard 6 speed freewheel from the Méral Randonneuse I am currently restoring.  Since the bike is already in great condition, probably the better word is “servicing” – there isn’t much restoration involved for this Méral, being very well preserved already.

Meral Randonneuse – early 1980’s

Sachs Maillard 6 speed freewheel

This freewheel looked sparkly after just a tiny bit of cleaning.  It spins sweetly, with that pleasant sound that some vintage freewheels emit, like a Suntour or a Regina. The freewheel is well engineered, and is lightweight.

Notched tooth pattern

As I was cleaning and lubricating this freewheel, with its useful 13-28 cogs, I noticed these interesting notches on the cog teeth.  That made me wonder if this was a freewheel designed for indexing, and perhaps added later to the bike.  But that didn’t make sense, as the Méral is equipped with friction Simplex downtube shifters, which were clearly original to the bike.

So, I did a bit of research to find out what model this was, as well as to determine the timeline involving the Maillard and Sachs companies, wondering when they had merged.  According to Velobase and other sources, Maillard was absorbed into Sachs in 1980.  By 1989 the Maillard name was no longer used.  Sachs did indeed develop an indexing compatible freewheel, which supposedly can index with any system.  This was the ARIS model which stands for Advanced Rider Indexed System.  It appears the Aris line was developed in the late 1980s’, using their proprietary “Rapid Grip and Shift” tooth design.  So, why does early 1980’s this freewheel’s teeth have these notches?  Is it an early indexing model, or is it an idea that Maillard had developed before indexing was standard?  As far as I can tell, these notches in the cog teeth were present in early 1980’s models. has several Sachs Maillard freewheels from this era, all of which have the notches on the freewheel cog. Reader insight is welcome!

The freewheel takes a standard splined tool, which can be had from Park Tools or other suppliers.  That was a pleasant surprise.  And, I won’t be needing to overhaul this freewheel.  With a little bit of lubrication – a light oil at first, and then heavier automotive oil – this freewheel will probably last another 35 years or more, and we’ll see how these notched teeth work out on the road.
