I’m definitely appreciative of the effort. Especially as I’m sure I’ll warp the crap out of the current rotor eventually.
I think it’s a really great step that you have the new sample rotors to test. But it’s also just hard to get all of us on the same page when there are so many options. Hard to have a tribunal over the forum so it’ll probably just take more time for things to be agreed upon and be less up in the air
Appreciation, appreciated - Dane! 
I think you’re right. I suspect it may end up having to be less democratic and more like whatever gets worked out as this is discussed with BrakeStuff.
I will take my foot of the gas here a bit as I’ve been trying run with this when we’re at the toddling stages really.
Less haste more speed really.
Sorry if my message was a bit blunt.
It took me a while to understand that an asymmetrical disc isn’t quite the same as an asymmetrical rim… I was looking for an asymmetrical left-right… 
I’ll have to find the time to check that a 203mm disc is sufficient.
It’s true that a 220mm disc gives more clearance for the caliper and may be less likely to be contaminated by grease from the hub…
Do you see any real downside in using a 220mm disc? I have 2, but they aren’t big:
Back to this thread - any news on the prototypes? Are they better than the official rotors? 
Today, I’ve finally found time to install the offset rotor @aws sent me a few weeks ago. I had to file the adapter to make room for it but it seems way more stiff than the official rotor. I’ll try and get a try during the next days
I’ve also checked the brake pads. They wear really fast. Almost faster than on my freewheel! I have probably ridden 400~500 km and 2500~3000 m of elevation but they are nearly dead. I hope the new rotor will help prevent the wear.
What kind of brake pads are you using? Organic/resin pads will wear faster but cause less wear on the rotor. Sintered/metallic pads will not wear as fast but will cause more wear on the rotor.
Sadly I’ve not had the scope to test my rotor yet. Planning to move it to my G36er for a better chance to test it.
I did hear from Becky that it is better in terms of braking performance but still heats up and the metal distorts but in a wavey shape rather than like a place with the official rotors.
So yes the current feeling is that an asymmetrical one is still needed but progress in that direction is slower at the moment. I have spoken to Roger about this and it looks like he may help with some designing of such a rotor to help with the process of getting BrakeStuff to shift forwards in this.
But don’t hold me (or him) to that.
I will try and test my one soon! (I stupidly cannot ride at the moment due to my tattoos 
)
My pads are metallic. So that’s even more frightening!
Even though they were organic, it would not have been normal - compared to usual big brands rotors.
Thanks for the follow up! Let’s hope BrakeStuff will try and make the next prototype as 220mm 
Small update!
Good morning, I will make you a draft in the coming days, first of the 203mm disc and then the 220mm.
So things are back up and moving (a bit).
And we may even get the option of a floating rotor design made by Hope for these uni-hubs too 
And Florian Schlumpf will send me the new prototype of hardened disc. Hope this one will be better than the fist one
In the meantime, the one modified by @aws seems to work really great! Still had no time to go for a mountain ride (because of Grischa Muni Challenge 
), but I try and take some time in the next weeks…!
If you need help testing a disc, I’d be happy to help
I’m back on G36 
Just a few pictures of my metal pads after a few hundreds of km on Schlumpf’s first rotor model. Don’t they look nice?
I finally took some time to replace them with organic pads (on the rotor @aws kindly sent to me). I hope the brake power will come back! I’ll give them a try today during one of my daily trainings
Did you wear through those pads entirely?
I would say there is still a bit of material. But one of them seems to be glazed (is that the right word?).
I think I’ve rode a bit less than 500 km on these… So, not much for them to be so worn out.
It’s been a while. Is there a future in “after market” rotors?
I’ve had to politely chase BrakeStuff twice on this and the first time I was assured designs would be over to me in a matter of days. More recently I was asked again what size I’d like to try first. I stated 203 as that’s probably the most useful asymmetrical one if we have to one at a time.
I’ve not heard back since. I don’t want to become a pest or annoying so I’ll leave it for a bit. But I am wondering if I need to message again….
Update on these rotors.
As the option to get more rotors made in this testing phase wasn’t really possible - the idea of my ordering them for my own entertainment (while very tempting) wasn’t a logical step and my skill in geared riding let alone braking is minimal at best.
So I’ve gone with the option to have @Maxence and @toutestbon test out the 220 and 203 rotors respectively.
This to me feels logical as everyone will then know how much of an improvement these asymmetrical rotors and sizes make for geared wheels - principally on G36ers.
The unicycling geek in me is a tad crestfallen that I won’t get to see one of these new beauties in the metal - but I think they’ll end up working very well and perhaps after testing with maybe a few tweaks to design, we’ll all be able to place direct and official retail product orders from BrakeStuff.
Prices should be in the 75-85€ region I think.
Mid-stage design photo to give an idea. These will have a Shimano style hole punch design on the rotor braking surface edge.
Back to this thread! I have received both rotors late December. Due to a shoulder injury, I have not ridden that much since then (maybe 200 km, mainly flat sections). The rotors look great and fit perfectly on the hub. The 220 mm rotor that I use seem to offer plenty of braking power, but I’ll have to test it out on long downhill before being able to say whether they are better than Schlumpf’s.
I’ll let you know when there is more to share
Any feedback with BrakeStuff rotors ?
Not much since my last message. I still haven’t had the time to do long and hilly rides. The rotor behaves great during my city rides, though. It doesn’t seem to wear out so far. I hope that, with the sun that slowly comes back, I’ll be able to go and have longer rides
