The mold and shape of this CF rim is made for 32 holes, not possible to drill it at 36
Strange that guys from 36 MTB didn’t care about unicycle market, 10 years ago they contacted us when they developed the off road VEE tyre

It would be interesting to know how large the 36" bike market is worldwide but if it’s sizeable then I’d have expected to see another aluminium 36" rim before now. It only seems to be Qu-Ax and Nimbus making them at present.
the bike-market ist at least twice as big (since two tires) but still really, really small. just like the 36" unicycle-market unfortunately.

Oh, that makes sense. I guess it’s up to UDC to drill the hubs to match.
Yes but Schlumpf hub is only 36 holes !
People who ride G36 want for most of them have a lighter wheel and put the money to get it, this is a pity. For me it’s ok, I don’t ride Schlumpf and found a 32 holes hub from Nimbus in the end of last year, so I can enjoy my 36" CF rim

Does it make sense to have an adaptor 36h to 32h and go on using an EDB spirit crank with the Ghub?
Depending on what you want to achieve, it could make sense. I have a very precise idea of what I want for my G36: aerobars and a brake for each of my position - sat on the seat or laid down on the aerobars. To achieve that goal, I have to set an internal and an external discs. So I still find EDB Spirit cranks useful.
However, if you don’t want to have two discs, you can perfectly go for some more traditional cranks with a littler q factor. You should look at @toutestbon pictures : he uses Venture cranks.
If you are lucky enough to have Spirit cranks, Schlumpf hub and a frame that works with them, for sure. A simple adapter from 36h to 32h would be fairly simple to make by having someone lasercut them from steel (pretty cheap to get done through internet services), and a drill to chamfer the edges and get the holes to final size.
I have some simple 36 to 48 (that I’m using laced with 32) adapter that I’m using on a Schlumph. No issues and it’s a very simple design.
I run spirit cranks with the Schlumph and would regardless of whether or not they carried a rotor, they are a nice shape for shifting and have just the right q-factor for me on standard width hubs.
In my opinion, after the misadventures I had with the schlumpf hub, it doesn’t make sense. The adapter (designed by Martin and Roger and available soon) allows as much to go from 36h to 32 as to mount a disc on the hub. An EDB can cause a lot of damage to the schlumpf hub, and it is not possible to brake and downshift at the same time.

If you want to brake in every hand position you can DIY your brake lever. I made the longest existing brake lever because noone seems to make them. But it was really easy, cheap and fast
I’ve seen your modified brake lever but it won’t work on my G36. The brake lever should measure at least 50 cm and couldn’t be straight because of the shape of the KH T-bar.
That’s all about your will, tools and time. I just used a shorter iron squared bar, but was easy to cut and get the shape using the required tools. Longer and more bended shapes can be achieved (if you look at your lever you can easily guess how and wherea it was pressed, cutted and bent)
Translation: that’s about 207 off and 414 kPa on the road.
Take a look at the Shimano GRX inline levers ( BL-RX812). I’ve yet to give them a try, but that should enable you to have a lever in both positions with a single disk.
I fancy doing it for my freewheel so I can have a lever on both sides of my t-bar in an easy to reach position (I hate the central mounting setup).

Looks great! How do you mount it? Do you simply put a duct - is this the right name for the part having the oil in it? - on both sides of this lever?
I have been looking for something llike this but never ffound before.
Yeah, the lever installs inline:
As it’s designed to mount on the wide section of bars (31.8mm) it may well need some serious (off-centre) shimming to mount nicely on bar ends (22.2mm) but I doubt it’d be too much of an issue.
It may well be that the metal strap clamp could just be re-drilled to be shorter.
On all of the pictures I’ve seen it’s also looked like it was out at a bit of a weird angle, but the specs say that it has reach adjustment.

Why do you say that an EDB can cause damage to the Schlumof hub? I’ve been using one on mine (#428) with no issues whatsoever.
I could imagine doing some damage if braking during a shift, but otherwise I wouldn’t worry about it.
