What hubs are these?

Lewis Moon · #1 08-29-2019, 08:43 AM

These wheels came on my El Mariachi and I need to rehab the rear. Unfortunately, I can't seem to find any markings to see who made them.
Particulars: Wheels: Stan's ZTR Arch 29er rims. The rims themselves are kind of "road narrow" so these are probably over 5 years old. The rear hub has sealed bearings with a standard sized steel QR axle that has a bulge on the inside drive side to support the inner race on the DS bearing. The "cones" or end caps, if you will, thread onto the axle and have 15mm flats for a cone wrench. They are six bolt disc. There are nice rubber seals pressed in on both sides.

Front hub is the same maker but takes a humongous Rockshox Reba thru axle.

My first thought is that the shape appears like Hugi.

I was thinking hugi too, but the end caps were never threaded only pressed on if I recall correctly and the front end caps in the picture have more machining on the end caps then I remember as well.

What kind of mechanism is inside the hub? Hugi and DT are the same thing.

I'll need to get in to look at that. The freehub didn't come off with gentle pulling when I had the axle off and I really didn't want to apply more pressure until I knew what hubs they were and how they went together.
Catch 22.

Sounds like you should take the cassette off and get a better looksee.
Good luck!

I had the cassette off and the axle out but the freehub wouldn't come off with a good tug. Probably a seal but I didn't want to push it until I knew I wouldn;t break anything.

I did a search with "Hugi disc" and found a set that looks almost exactly like these... Except they're 240s, which means they have a different axle. ... But then again, the DT 340 came with steel axles so it may be an older Hugi.

If they're convertible to thru axle, I'd do it for sure! I have brand new salsa mariachi thru axle drop outs that will work on your frame I can sell too haha

Well, I tried to pull the freehub off again and it looks as if there is a sleeve that extends through both the DS hub and freehub bearings to accommodate the smaller diameter threaded steel axle. This is hopefully a press fit. I'm going to try to tap it out today. I may be able to retrofit it with a thru axle...

Well, that was weird. From what I saw in there, there isn't a drive side hub bering! The "sleeve" I saw is actually is some sort of subsidery axle and the hub and freehub act as one unit. The two bearings that bear weight are the regular NDS bearing and the outside freehub bearing. There are splines on the inside of the sleeve so it looks like I would need a special tool to get the freehub off.

Thbis sounds just like the Shimano design that uses a hollow bolt to secure the inner shell of the freehub body.

The "splines" are likely just a 12-pt "hex" that you can engage with some metric hex key size!
I've even used the four relatively sharp points of a high-quality 3/8" socket extension to successfully remove one brand of freehub's hollow bolt (lower-end Fulcrum I think).
