Greetings for your modifications! I’d be happy to try out your Magura 203 rotor if you’re in Europe

In case helpful!
Many thanks @Mayor_McCheese for the bolt. I’m really happy to have a growing and now complete Hub ToolKit

Just a thought… why are we not going for floating rotor?
Aren’t they harder to build? I guess the non-floating one-piece rotor is easy to cut from a piece of metal.
A question… we have someone who has ordered (and paid for) a new schlumpf, they had it built into a 27.5 wheel (dominator 2 rim). Now wants to cancel the order. Does anyone think there is a market for a complete 27.5 wheel with out waiting for it, or should we take it apart again and sell it as a hub?

That would be nice. I wouldn’t mind an adaptor type system that allows for us to mount a donor edge from say the 220 Magura rotors or a Shimano one like used on BrakeFast.
Just getting it drawn up very precisely and with somewhat ease of assembly that would be key.
Edit: like this work that was started on this area

I would picture there could be quite a market for that. Remember in days gone by seeing CDK in France showing complete schlumpf unicycles for sale. And the fact it was a realised item kind of made it more attractive.
(Note to self: do not need another hub, do not need another hub, do not need another hub!)

Floating rotors are good, but I think they should not be necessary. Plenty of MTB DH worldcup riders run simple disks, if they don’t warp them, the disk on a schlumpf with larger mounting diameter and a big aluminium heatsink of a hub not so far away should be fine with a proper design.
I think either Schlumpf revising their design, or Brakestuff making one that is not just a different material but also a more conventional design with angled spokes and staggered holes in the wear surface is the best solution.
I did draw an adapter to the 203mm Icetech outer disk which would probably end up being “semi floating” but from hearing/extrapolating the pricing brakestuff can probably achieve, I don’t think it would be an attractive solution long term. (Although it would be fairly easy to develop)

I tend to agree on this point. I like the adaptor idea solely that people can buy rotors for the edge part more off the shelf - but it does require more work.
I discovered quickly that in order for BrakeStuff to get a really precise drawing of the interface they needed a physical rotor being sent to them - which I did, and without that I don’t think it would have been safe for them to make a rotor as even a single mm here or there can impact the way it securely fits.
But it would be great to get a direct 1:1 copy drawing of the interface, made up to an adaptor option out in the open source / public domain so that there is the option for those that want to tinker or make their own disc option that floats and rotates asymmetrically

No, but they do look rather nice, especially the Hope ones… 
I think one of the Hope 220mm vented floating discs and a V4 brake would be the top-end of performance…
Interestingly, when I first saw the wavy sine-wave type profile on the new Schlumpf brake mount it made me think of the early Hope disc fixing before the six-bolt standard was around, albeit it was a lot smaller diameter (there were no bolts on it – a bit like a Shimano centrelock without the splines but that wavy profile instead (as I recall)). I built a set of tandem wheels on Hope Tandem hubs with that disc fixing back in the mid '90s – things moved on though!

One possibility could be to list it as a wheelset and as a hub and see which one gets ordered first 
(however, it would ideally require the online shop software to support linked inventory to avoid the scenario where 2 people order the items and one get his order cancelled).
If the price hadn’t increased that much, I would be jumping on it…

Floating disc… Not for a company already making them, the expensive hardened disc part is common and the aluminium profiled section is easy to make. That is why I asked.

I thought you were talking about Florian, which probably doesn’t have the experience/capacities to make such a disc. And I don’t think BrakeStuff makes floating discs. Se we’d have to find another company 
Oh, I had not realised that BrakeStuff did not do floating rota’s. Due to the PCD of the schlumpf disc bolts there is less than normal flex for expansion of the disc when it gets hot, a floating rotor would deal with that.

Ok, here are some more pictures. I think the spokes they used are a bit thicker at the bottom (I had the wheel built, didn’t do it myself).
That’s annoying because I already had to return the wheel once because they mounted the spoke head the wrong way round even though I pointed them to the part in the manual where it says how to do it…

Thanks, sounds like I have to get washers…
That might help… as I do personally this it is best with washers in NDS.
But I’d be curious to know if @Joris had this kind of issue and come to think of it it seems like their build is closer to your set up.
(Hope you won’t mind me tagging you into this Joris!)
Really hope we can figure this out and get you up and running @r4nd1nt

Except for the wider rim that’s very close to my setup, yes.
Thanks for digging up all those helpful posts and people.

No, I didn’t have this problem myself. I used the 2mm spokes from einradladen.com (which I believe are the same spokes as from unicycle.co.uk), without any washers. The clearance I have at the non-disc side between the spokes and frame is somewhere in the 0.5-1mm range.

Thanks so much for the info Gocup!
The first Bike shop I found in Sydney had an upmarket spoke machine was going to charge me $2,50 per spoke which was ok, until he told me his machine couldn’t cut and roll spokes that long.
He was good enough to recommend another bike shop in Cremorne who was amazing and charged me just for the time to cut and roll 44 spokes (15minutes - $AUD.30) I’m so grateful for that! The job included cutting through the thread and continuing the thread from existing. And to think I was considering buying a spoke cutting/threading machine for AUD200+
He mentioned he builds bikes for some high profile Aussie cyclists and was a nice guy.
Looks like I will be building the wheel myself as no bike shops have stands for 36’ wheels.
I don’t mind, I have built wheels before. Yes, will use the frame as a stand.
Do I have to use specifically spoke head washers?
Can I just use any washers I find that have hole just slightly larger than spoke diameter? I guess the material needs to suit the schlumpf hub. Brass only?
I know of a spoke supplier online in WA Aust.
So shopping list remaining for my G36" build:
138mm crank
2 mm spacers
Pretightening axle bolts ( found some)
KH Tee bar set ( just to use the L brackets and TBar sleeve) I might make these myself, possibly.
Shimano XT brake lever and calipers
Aero bar (enclosed or two bent bars) might depend on if I can mount the brake caliper on enclosed aero bars.I think enclosed Aero bars seem to handle ground impacts better? I put a tennis ball on the end of my current enclosed aerobars.
For pedals, I’m going to re-use my KH stock welgo pedals. I really like them… nice and grippy even after taking off the pins. And robust. I avoid pins on pedals..( my best scars…on my calves can attest to that)
