Which means: the disc brake tab has to be on the right side of the frame, not on the left side as it is on the QX frames.
You can still use a d’Brake on this side, but since the RGB frames don’t come with magura mounts, you aren’t even able to add a Hugo-Strut. (By the way: Hugo, the inventor of the Hugo-Strut died two weeks ago 
)
If you want a colored frame that allows disc brake with a Schlumpf hub, take and modify a Mad4one frame.
Mad4One has disc tab on both Left and Right sides
Thanks for the explanation! Isn’t it possible to reverse the frame to have the tab on the right side?
Does Mad4One have 36er frame? I haven’t found any size for their frames on their website.
You’re almost New here, did you already ride a Schlumpf hub ? What is your experience of Unicycling ?
Flansberrium will make the frame you need 
The tab has to be on the left-back of the disk, flipping the frame around doesn’t change anything to this as the tab moves forward, so it’s still on the wrong side.
I haven’t seen a 36’’ mad4one frame, I dont thing he had any built.
-
as Jacob said already: turning frame will not help
-
mad4one does not have a 36 frame
-
for a 36 frame (with Schlumpf) plus external disc there are at least 3 options:
- KH frame
- Quax frame with D-Brake
- a specifically made Flansberrium -
Nimbus oracle 36 frame won´t work with Schlumpf as it has 125mm bearing spacing.
… but both with modifications! Neither a QX-frame, nor a d’Brake fit a Schlumpf hub! See here, what needs to be modified.
The bearing housing wasn’t too tight. This was the problem. Maybe wrong serie of the frames from factory. This is the reason why knurled bearing was slipped and there was no marks on the bearing housing from the knurled bearing. I made a little modification on the new frame (photo). It´s OK now. Thanks for all your replies.
Hi all,
This has probably been discussed before and there are no right answers or conclusions. I have KH26 which I like very much and I use it weekly to ride technical trails. However, not all trails here are technical, and sometimes I’d like to go further more easily to reach new trails and forest areas.
So I’d like to ask is there someone who has been in similar situation and has found gear hub useful?
I now the hub is good, but by the same amount of money I could buy a new 29er for easier trails and a 36er for touring or a good bicycle.
I guess my alternatives could be to learn to increase cadence to fast spinning on easy sections or to use a bicycle to take my uni to new areas. A 26er is also compact in size and can be taken to public transport when going further away.
It’s just money…
If spending money is not an issue, get the Schlumpf geared hub and enjoy. If you’re thrifty, forget spending your hard earned cash.
You later will most likely regret whichever choice you make.
I put a lot of technical downhill miles on both a KH24 Schlumpf hub and a KH26 Schlumpf hub, enjoying both immensely. Yes, I have purchased five different Schlumpf hubs. Only one still works (I gave this one away new to a friend and later bought it back from a pawnshop), two are literally worn out, two have been on a ski vacation in Switzerland for almost two years waiting for warranty repairs, and I have also previously had two warranty replacements hubs. Plus Kris loaned me his personal Schlumpf after mine broke a couple weeks before my 24 hour Seattle to Portland 204 mile event ride.
My favorite technical downhill unicycle was the KH24 Schlumpf. It was the most versatile and the most fun.
You will enjoy the KH26 with a Schlumpf,
JM

I had exactly this situation as well, I ended up getting the Schlumpf and was super happy. You have to be careful though, as riding the Schlumpf hub for technical riding obviously wears out everything much quicker that a normal uni or riding the schlumpf only on the road.
My hub is now only riding on the road. I got tired of paying the expensive bearings and replacing them. I’d probably enjoy the hub for muni just as much as I used to, but I feel like I’d rather pedal more and pay less hahaha.
As BungeeJoe said, if you have the money, go for it, it’s awesome. If not, just pedal more!
I bought a Schlumpf hub for the same reasons: To get to and from the trail head fast on one wheel. I guess I also just wanted to try it because it sounded awsome. I rode it for a couple of years before it ended up collecting dust in the attic. It is not the same as a bicycle with/without gears. It’s hard to ride unless it’s fairly flat. I now use a regluar muni and either a car or a bicycle to get to the woods. I would get a 36’er before buying a Schlumpf hub.
After 4-5 years in the attic, I put the Schlumpf hub in a 29’er. I now use it in the winter on bike paths with a studded tyre. The long flat boring sections has now become the fun sections, so I’m happy with the Schlumpf hub, but it’s different from what I thought it would be. A lot of people ends up selling their Schlumpf hubs, luckily there is a second hand market for them.
I’ve spent a lot of money on unicycle stuff, and the problem is that it’s there to remind me that I should have paid morgage or other sensible adult stuff. I’ve wasted way more money on things I don’t longer have (food, alcohol, vacations etc.), and never gave it a second thought.
Thanks for your input, I appreciate it!
bungeejoe and jaco_flans, is the wear in the hub mostly related to drops? Serviceability is hard to estimate, but can you throw a ratio how much quicker gear hub wears compared to regular KH hub? Does warranty repair work for the hub?
Terrain here is technical mostly due amount of roots, rocks, snow/mud and continuous up and down sections. Otherwise there are no over 100 m height differences or over 20 cm drops. I was thinking maybe gear hub would last in these conditions.
UniMyra, I like your uni videos, great work! 
I’m watching this discussion with interest, as I still haven’t decided between getting a small-wheel geared Muni or a medium-wheel nongeared Muni. My usual terrain varies between nontechnical XC and medium-technical muni. No big drops (which I can’t do anyways).
Currently I use a 24x3" with 137 mm cranks, which is OK on the more technical bits but a bit too slow on the flatter parts.
I’ll share my own experiences with the Schlumpf hub.
I bought one of the most recent 800 series muni hubs directly from Florian and had it shipped to Silva Cycles for installation into a 19" wheel. On my first ride, a crank bolt came loose and froze the button in place. I had to send the wheel back to Silva for repair. Duh, I had somehow assumed everything was tight.
After Silva fixed the wheel, a crank bolt came loose during the very next ride. I realized I would have to constantly check tightness. Silva told me they were unable to tighten the crank bolts very tight, because the cranks would bottom out. Neither Silva nor I were aware of the new design of the 800 series hub, allowing a “crank stop”, allowing spacers to push hard against the hub.
I started using spacers, and I changed cranks from Ventures to Impact Eiffel. I have Eiffel cranks on my trials/street uni, and they never need tightening. So, I figured the Eiffel cranks would make a better interface with my Schlumpf hub. I could tighten the crap out of the bolts, now.
So, things improved, but I still had to re-tighten the cranks fairly often. The inside of the bolts were deforming. I spoke with Silva Cycles and they said they also had problems with “buggering” the crank bolts. So, I ordered another pair of crank bolts from Florian.
This summer, after taking a long ride, the plug in one of the buttons stripped while I was loosening it. I had only used the torque driver from Florian to loosen and tighten the buttons. At that point I tried hack sawing the button off. The whole thing got screwed up, and I have to send it back to Florian for service.
I am concerned that the same issues, related to the material strength of the crank/hub bolts and the button plugs…are going to affect me in the future.
I have come to the conclusion that the Schlumpf hub is not good for muni, even though it’s called a “muni” hub. I tend to pivot the uni around while riding muni, and that seems to cause more accidental button shifts / momentary freewheeling. I am also heavy, weighing 210 lbs, and I feel that even small drops are too much for the hub/crank interface.
Once the hub is fixed, I plan on installing it in a 24" wheel. That’d be fun for cruising and XC riding. 24" in high gear is about as fast as I care to ride.
Anybody who thinks the hub is a magic bullet…should think twice. I’ve gotten a lot of fun out of mine, but it’s also caused headaches.
When I was living in Australia the only unicycle I had was a 26" Schlumpf. It was perfect for the highly variable terrain I rode on. It takes some getting used to the little bit of slop in the gears, even when riding in 1:1, but after a while you hardly notice it.
They do take considerably more effort to keep maintained than a regular unicycle hub, but then a regular unicycle is practically maintenance free compared to more complicated devices like multi-speed bikes, or geared unicycles 
They are a bit pricey, but a great novelty and allow you to go faster on a smallish wheel. Like many others on here I own two of them. I bought the second one used when I sent my first one in with the recall. One is currently in a 26 and the other in a 32" and are currently working well.
Well, a regular hub only need bearings repacked/replaced every few years. A Schlumpf hub has a total of 9 bearings inside. Mine had bearings replaced twice in 4 years of riding. The disk brakes make the bearings wear quicker as well (even on the new generation).
The warranty does not cover wear, it only covers manufacturing defects. Bearings wearing out is normal use unfortunately.
If you have one, be careful, test it’s limit (the hub is pretty tough still!), ride it and have fun

interesting comment, and that is why I put the disc on the hub of my schlumf so the brake torque does not transmit through the gears.
see my adapter on page 101 of this post.
new style Schlumpf hub
Hello again, while rooting around in the garage I found this disc adapter for a 48 spoke rim, 36 hole schlumpf hub. It could probably be re-drilled for a different rim spoke pattern. That means fare game to anyone with abilities like Jaco-Flans or Saskatchewanian because this had to be remade due to mistakes. Oh the disc measures 8" across, and it was made for the new generation hubs.
