Isn’t that hub a CV?
Hmmm, I guess it is fixed, which might work if it could be hot swapped, but as a permanent fixed gear it would require multiple wheels sets.
There’s so many threads on this topic, but there is only one succesful geared hub, which is why I was asking about the patent since it precludes anyone setting up shop and refining it or even fixing them without the patent owner’s permission.
And all I want is a smaller gain, 25%…this would be totally usable as a daily trail rider, would probably have one on my 29er as well, so that’s two hubs in regular use vs one hub that gets no use. Could be there is a market, cuz I can’t be the only one; Tholub?
Yup… 1.25 would by nice… maybe Florian would consider doing them so they could be exchanged to a 1.5 at a later date??
I’ve done over 3500 miles of G36 riding. The last 3000 has all been on my “new” one (late 2008, #225). It just works and works - I would be devastated if I didn’t have one rideable. Would switch to bike! Luckily my older one (#56) that Beau and I put maybe 1500 miles on total is also still good as a backup and occasional loaner.

Since there is no visual way to see how much grease is left in the hub, (without taking it apart! DON’T!) how would you know when it’s time to add more…short of it seizing up, falling apart, etc, haha. And I also wonder that if you’re seeing an excessive amount coming out of the hub via the seals, if that means there is maybe a bit too much inside.
That was happening to my hub for the first few months of riding, but now the “leakage” has almost completely stopped. So I don’t know if that means it’s time to add more, or simply that the excess grease has made its way out. 
Maybe add half a syringe and see if you start getting leakage again?
Over time, maybe you’ll observe a cause and effect.
I don’t pay attention enough to leakage so I’ve just added half a syringe a couple times a year.
Check your PM.
Thanks for the grease man!
You’re welcome Kc!
My 3-pack is on the way too! 
actually it does, but the arm that holds the sun gear to the frame has to be bolted to the hub, which you obviously cant do while riding
Wow 50 pages!!! As I am a new owner of a Schlumpf I better start reading this thread as I’m sure there is a lot of good info here…please tell me if I shouldnt bother.
Riding my geared 36er in high gear makes it feel like a “virtual” 56.25 inch wheel (Schlumpf ratio is 1.5625). I have always had to “imagine” (to try and get my brain to “talk” to my legs) that I was pushing a 56" wheel. Now I have an actual picture of what that would look like. See QU-AX FaceBook page for more pictures.
wow!
Great!
Who is that man?
Where to buy such a monster uni? It’s not listed on the Qu-Ax internet page.

These people are not that far from you. They usually have a few different sizes in stock.
They will let you special order or take the class and build your own.

John Foss’ hub update:
After Florian’s first cryptic/mysterious message to me on Jan. 22, he followed on Feb. 14 with the question of what would I like to have laser-etched on my new hub? Woohoo! I replied, and then later that same day, he sent me another email with a picture of my new hub! It says “John Foss, the Uni-Cyclone”; predictable, eh?
Then I waited with baited breath for it to show up at my house.
And waited…
And then on March 1, an email from Bronson Silva (Silvacycles.com), the maker of my beautiful custom 36". “I have your repaired hub.” Florian sent it, not to me, but to Bronson who only lives 130 miles away. Hmm. I’ve got the rest of the wheel and Bronson has the hub. Uh, we’re still figuring out how I get his wheel back to him, and me get my parts back without me killing a day to do it. Looks like we’re going to ship them back & forth. But soon (I hope) I will be riding on my new hub! 
Better to use the # of posts; page count depends on your user settings. This is post #756!
Is that the correct math? I always thought it was like a 54" wheel. I’ve ridden a 56" wheel before. It’s very different from riding a geared-up 36" wheel, but at least the 56" fits into the car. 
That “Qu-Ax” 56" wheel is a beauty. I especially love the clever use of those rubber bumpers on the ends of the pedals. Big wheels are very susceptible to pedal (and crank, and potentially axle) damage in drops. When a wheel that size falls over, it’s quite an impact on the crankset!
My old roommate had built a set of handmade big wheels, Tom Miller style. He had a 40", 50" and 56". Adding my 45" filled in the gap. Those were great novelty cycles for road riding, but not comfortable, not light, and the big one was not good for hills. Limited to 140mm cranks due to leg length, it was scary riding down even little hills! 
Glad to hear the hub is at least in the right country. Simple solution to the swapping plan. You come over some Saturday afternoon (when he has time), drop the wheel off at Bronson’s, he builds it. Then we go out for a pre-ride awesome dinner and then do a big ride the next day.

Glad to hear that your hub has returned John. Mine showed up on Feb 25 without warning. It was a very nice surprise. So far I have put about 100 miles on it. Still working flawlessly.
I dont know if it has been answered before, but I dont want to read all the other 758 posts to find out… I’ve had my Schlumpf hub for 2 weeks now and I absolutely love it! I’ve been riding alot of Muni on it lately, and it’s pretty much mud everywhere at this time of the year. Is there anything I have to not do to wash it? Or does it even matter if it’s covered in mud?
Also, I noticed today that the bearing protector on the grey side of the hub (you know, where the 6 bolts are on the hub) is moving. It moves and stick on the bearing holder, which also makes noise. Is this normal? Is there anything I can do to fix this?
Thanks!
