Identify a freewheel please!
 

Anyone have any idea what freewheel this is? It seems to resemble a Taiwanese Falcon, but I don’t remember those having 7 speeds?

It is attached to a Mavic 550 hub.

It is not the best picture. I know, it is not your picture but one that someone posted on eBay to sell it. So you don't have control over that. It used to be that sellers would provide more details. That seems to have faded away. A couple of crappy pictures is all you get now. I thought Falcon had 7 speed freewheels.

Think what we got here is an 8 speed freehub rather than a freewheel.
(Tell is that seven cogs are retained with a Bottom Bracket lock ring,)

Compare with:

(Picture shamelessly snatched from this eBay listing for a Mavic 571 freehub, Not going deeper Because Lazy. Let us know what you do find?)

Holy mackeral, I hope you're right. That's why it looked so weird to me? I ended up buying the wheelset because I love the 550 series hubs, and the tubular rims looked pristine...but I didn't remotely think that it was a freehub (I knew the later ones like 571 crossed over).

However, the hubset is definitely the 500/550RD looking ones. Did those 571 labels slide off, or were they part of the hub body?

Here are some more pics.

Definitely doesn't have the 571 logo

Very much looks 550ish

Why I bought them


I am truly surprised. I should have looked harder. Falcon DOES have a 7 speed.

But it doesn't really look like the cogset pictured either.

Hope you are right. That would be cool!

The lockring on the smallest sprocket makes me think it could be a Singapore-made Shimano SIS freewheel:

I kind of aagree about it being a shipmano 7spd HG. It's a real lousy pic though

Definitely a 7-speed freewheel. Those Asian clusters are a bit of a blessing, really. They are of passably decent quality, cheap as dirt, and keep many an older bike rolling happily along.

It is either a modern day Shimano or a Falcon based on the sloped cogs and lock ring. The Falcon ones are a cheap knockoff of Shimano. Based on the quality of the wheel, I doubt it was made by Falcon. Both useva standard Shimano removal tool, which is the most common freewheel removal tool for anything made from 1990s-modern day.

One more vote for a freewheel and not a cassette. Sunrace also makes freewheels that look very similar.

Tubular wheelset! :D :thumb:

I checked a bit more on velobase whether the 550 series ever added a freehub and it doesn't look that way so I am assuming 7 speed freewheel. Whether it is Shimano or Sunrace or the Falcon, we shall soon see.

Based on a closer look, the cogs seem to have that Sunrace finish to them. Though the ones I have seen with a lockring tend to be iron colored or have an iron-black first cog.

Mystery solved. It is, in fact, a Shimano freewheel. XJ model made in Singapore as John surmised above. Interesting. Since this will be going on a AD Superleicht with Suntour Superbe stuff otherwise, will have to swap it for a Sachs freewheel!

Tires are Graphene Corsa Control and do not look used at all, really.

So,
Ambrosio Durex Super Pro rims
Mavic 550/501 hubs with the correct skewers
Vittoria Corsa Control tubulars already installed
Now disposable XJ Freewheel

For $80 plus $50 shipping. I think that was a decent deal.
