That seems nice, maybe se can use it only to protect the cables at the headset level

Hey all, finally building my beast!
For sure going to order carbon cranks, and the Nukeproof headset. This stock headset is not good.
Unfortunately mine came with v2 screen so I need to replace it with v3.
720wh and I’ll get a full weight for you once I’ve got shock bushings. I have full build list but right now I’m just below 4k usd with very high end components shopping sales over the last few months.
Does anyone have links to a lighter spider?
Also is there anyone with a phone mount 3d printer for the fake power button spot on top of the frame?

non integrated headset is the best. Brand like Santa Cruz and Specialized still using external routing cable port.

On both CEF49 and CEF50 frames I use Nukeproof Neutron ZS56. No water gets in and the wires are all intact
Are you sure the thread its 1.5, i got this diagram from Linda and size is M12x1 183MM and thread length 19mm

How are you using a 150mm? there is no way that reaches across and threads in?
@calvintys I believe its a 1.5 I dont know what that diagram is. This is the kind of thing that drives me crazy about dealing with China, nothing is ever correct, the initial diagram I got had a shock bushing at 44x8 instead of 22.2x8. that was fun and cost me a couple days on my build. maybe thats the new size for the UDH rear triangle?

I have a conventional hanger, not UDH.
I hear yeah, definitely frustrating. My main pivot bolt was too short by 10 mm. I had to have a custom TI replacement (upgrade) made before a big riding trip. Cost $80 but only took a week rather than 4-6+ weeks for a free warranty bolt from SZZS.
The trip was awesome, so I got lucky. DIY has it's inherent risks unfortunately. Especially, on the first iteration. Fortunately, SZZS seems to want to correct it's errors, thus still worth the ride quality for my CEF50 build.
but even the conventional hanger is 179mm so you would need a 180 or 178mm axle length?I have a conventional hanger, not UDH.

I've built 2 dengfu e10 with m600 and a couple bbshd commuters so I am no stranger to DIY, its always just a bit frustrating though that you never really know what you are going to get until it gets there and you measure for yourself.
I'm hoping they ship out new headsets to all their customers, the current one is absolute garbage and we all will be replacing cables and brake lines before too long. The nukeproof one doesnt seem to be available in the USA. I will be upgrading to UDH triangle, 160 carbon cranks once its available. Transmission is a must for ebike, the shifting under load is so nice!
I'm about to pull the trigger on the LCE930 in size small and build one for my kid for Christmas so there is another custom bike on my list
... I have a problem!!! Send help!

178 mm is the Hardlite TA upgrade. Same as Mike posted earlier. Seems to work well.but even the conventional hanger is 179mm so you would need a 180 or 178mm axle length?

Upgraded headset update: Linda just sent me this today.
She says $30 USD ready to ship apparently. That's all I know. I'm just doing the upper (4 arrows) for $18.

I'm pretty sure you can get it from chain reaction to the USA. I order stuff all the time from there and never have a problem.

Aaaargh! Just severed the delicate changing port wires blk/red when I was changing out my shredded dropper cable yesterday. 🫣
I ordered a replacement that will be shipped with my other warranty parts...so yeah! I saved $15-20 on shipping.
So, I guess that $20 savings will now finance my cheapo soldering kit from Amazon.
New DIY acquired skill...yeah soldering!

At least SOME good news for me! 
New upgraded Hope dropper remote and new cable/housing successfully installed. Matching bling for me!
Now we'll see if I can successfully solder those tiny charging port wires competently in order to actually ride this weekend!

Don't confuse the over lock nut convention i.e. 148x12 boost vs the actual measurement including threads of 179mm.
Just a reminder for newcomers that I created a specifications thread with all the specs I could find in one place.

So my build's starting to take shape (I'm thankful the M820 uses the traditional 8 splined isis crank design).
And i'm equally happy that Bafang have embraced the disk magnet sensor, compared to the spoke magnet sensor.
And cable routing was fairly simple (although, make sure you route the disk magnet sensor cable first, before routing the rear brake hose).
But my question is about the fork style which should be ran (1.5 tapered or 1.8 supertapered).
Initially, I was going to slap in some 160mm travel Fox 36s with the traditional 1.5 tapered steerer. But now I'm thinking maybe, I should simply go with a Zeb with the 1.8 supertapered steerer.
Has anyone built up a cef50 using a supertapered fork like a zeb or domain. Or have we simply used a 1.8 crown race adapter?
The bottom race on the CEF50 is 150 not 180.
*I should have said the bottom bearing seat on the headtube.

Oh!!
Mine came supplied with a zs56/66 headset to support a 1.8 supertapered steerer fork.
The upper headset cups is a zs56. The lower is a zs66 with a 1.8 crown race.
Interesting
Mine is a ZS56 28.6/ZS66 with a 40mm crown which fits my Fox tapered 1.5 fork.
