Your best option is the CS-MB001 frame that can accommodate up to 40T 1x11 chainring.

Usual MTB frames allow up to 36T 1x11. There is a thread about this here: http://chinertown.com/index.php/topic,627.0.html (in those days fast-geared MTB bikes were not a thing so a lot of discussion is about why the hell I would need a bigger chainring)

To have 50T chainring you need a 3xsomething setup for sure. Or you need a cyclocross frame with some big tires.

Thanks for the hint on that frame (AND THREAD) - though I dont really like the futuristic-look of it. But I will keep it in mind.
In the beginning I also had an Cyclocross frame in my mind, but I would like to run an Suspension-Fork. Therefore I switched to an MTB frame, so I dont have any troubles with geometry.

I'm afraid it won't work.
I run an oval 34 on it, that makes 15cm.
There would be enough space for 16, maybe 16.5cm but not more.

The chainline of the CX may be different, but I doubt you could add 4-5cm to it.

I highly doubt it will work with a 1x setup. For reference, I have the BSA bb with a SRAM GXP crankset / bottom bracket setup. The crankset is made for a 3x setup but I'm using the middle spot for the 32t ring and the outer spot for a bash ring. If I increased the diameter of the bash ring to match your 21cm measurement, it should work but will be very close. The downside is you would have to use the outer most option and the chain line really wouldn't work when you're in your granny gear. That being said, you might have to look at different frames or consider a different gear ratio as there is no way a 50t would fit in the middle ring option.

Thanks both of you for measuring it up!
That gives me at least the space I can calculate with - if I would stick with frame.

IMHO 50T is way too big to be running on that type of bike.

Im building up a similar style bike around one of these frames at the moment, actually most of my parts arrived today, just waiting on the workswell frame/fork :D

Im going to be running 2 x 10sp XT, will have plenty of range for speed on fireroads etc and also to easily climb whilst loaded up with bikepacking bags etc.

Ive also got a touring/gravel grinder/cyclocross bike which is set up with 11speed shimano, currently have a 48t big ring and would not want to go any bigger on that, off road with decent tires (even on road on this type of frame) i think you'll find 50T waaaay to big.

Anyway thats just my 2c.

You are probably right.
50T is just the chainring I have on two of my bikes, making me believe I have to stick with it.

But with your comment in mind I did check on my bike to get my "normal-speed" gear and that ratio.

      Chainring   Sprocket   Ratio   Feel
Fixed   50T   18T   2,77   mostly good
MTB   46T   16T   2,87   average gear
MTB   46T   14T   3,28   good speed - could go higher
Road   50T   17T   2,94   average gear
Road   50T   11T   4,54   Never really used

My normal Ratio is somewhat around 2,9. Highest speed should be okay with something around 4.0.

Therefore I though I could think about an 42T up front, still having enough average-speed sprockets i can choose from (14-15T would result in 3.0 and 2.8 ), having the highest ratio at 3.81 on the 11T-Sprocket.

Still: Fitting an 42T as a Chainring still seems a lil bit tricky... But at least its one step closer ;)

How many rings will it have up front? The more rings you have (1, 2, or 3) the further out the largest ring is. We need to know the effective chainline of the 50t ring to get an accurate measurement.

Thinking about getting an SRAM CX1 / 1x11. So it would be just the one 50T-Ring.

I would probably also go with an BSA-bb.
(Do the different Bottom Bracket have an significant difference in width - meaning the resulting chainline / distance to the frame?)

Thanks!  Great looking bike BTW...  I'm working on #2 which is the same frame in the 27.5" version for my brother.  Can't wait to log some miles.

Are you talking about the Workswell WCB-M-062 as an 27.5"?
If yes: Where can I find it?

Hello!
New to the forum, new to 29"-bikes...

Planning on a new bike to build up over the year - so i'm collecting parts and infos at the moment.
The idea is to create something which i can use for touring, getting out and do quite some miles a day, without caring about the terrain - aka a Gravelgrinder.
Therefore I would like to use a big chainring, something around 50T to be able to put up some speed.
But Iam wondering:

Does the M-062 fit such an big chainring? The Diameter of a 50T chainring is ~21cm.
Would somebody who runs the frame, measure it and give me note if it would interfere with the frame or not?

Thanks and hello from germany.
