Here you go

In general they can do any color you want, as long as you provide the right Pantone or RAL reference.
Here is a sheet with Pantone ones: https://docs.google.com/spreadsheets/d/1UZ6UEuG95xwcYVxeFkX9yzxlZV7NgETX8P8weUrZIV4/edit?usp=sharing

Beware your screen will show a color differently than the real one.

Look for a color you like, and then search pictures with the reference on the web.
To see items painted in that color. Again this is false colors, but it gives a better idea.

And the best is to look at physical color chart in a paint shop for instance.

Then you can draw patterns, add sequins, or a metallic effect, etc. at extra cost.

Re: The Shiny New AM831 Group Buy (A) Thread! Here is some more photos including rough measurements of the shock tunnel and fork clearance. The fork is a 150mm 51mm offfset Pike for reference. I'm still need to buy a few more parts before I can really start to build it up. Overall the frame looks really good!

Re: The Shiny New AM831 Group Buy (A) Thread! I have a L on order.  Eddy confirmed my address two days ago and said the frame was in painting process.

Guys,

Sorry if this has been asked multiple times already.  Is there a nice full parts list that someone has done for their build for this AM831 bike?

I'm kinda new to this whole "build from scratch" thingy...TIA!

A list of things you'll need to complete this bike, but not specific brands or equipment:
Things included -
Frame
Headset
Seatpost clamp
Rear axle
BB depends on when you buy and might not be useful depending on your crankset

Things you'll need:
150-170mm fork with a tapered steerer tube
210x55 shock
8x22mm rear shock mounting hardware (linkage side, need to confirm exact measurement)
8x30mm rear shock mounting hardware (front mount of frame)
31.6 seatpost - if it is a dropper make sure you get a lever if not included
165mm or 170mm crankset and chainring 30t or 32t - (any longer will be crank arm strike city)
BB92 bottom bracket for whatever type of crankset spindle you get
Rear derailleur
Shifter
Chain
Cassette
180mm rear rotor or larger (larger will require an adapter)
180mm, 200mm, or 203mm front rotor (pay attention if you need an adapter)
Brake levers and calipers front and rear, usually come with hoses
Wheels and tires
Headset spacers
Handlebar
Grips
Pedals
Stem
Saddle
Shifter housing and ends if you go mechanical

Optional bits-
Better IS42/52 headset (I hope it is 42mm, sometimes they have a slightly smaller bearing)
A stealth rear axle from a few pages back
Chain guide, bash guard, or combo

I think that is all you need to get on the trail but this is off the top of my head, hopefully someone else will fill in the blanks.

Re: The Shiny New AM831 Group Buy (A) Thread! Attaching a picture of my finished build. This frame size is "S".
Only the bottom cage is missing and I haven ridden it yet, apart up and down the street to tune suspension and saddle height.

Some interesting parts of my build:
  • assembling the lower pin of the rear shock was challenging, as I could not find any position of the rear triangle that gave me enough clearance to remove the bolt. I ended up unscrewing the top hinge form the frame (removing the 2 bolts just under the saddle). Not sure if that was the best choice because repositioning the hinge wasn't easy, but it worked
  • my mounting hardware for the shock was M8x30 and M8x22.199. The x30 (top) fit perfectly, the x22.199 was loose: i measured 22.86mm for the opening. Rather than ordering a new one, I 3d printed 2 spacers, which seem to work well
  • My shock is a Fox dpx2. It fits pretty well, but the access to the air valve is tight, I can barely connect my pump to the valve.
  • I used a Fox36 fork, that barely clears the frame, after using the 0.5 degree angle spacer from Reverse, which is about 10mm tall. BTW, jham asked about installing the angle spacer: it is an "interference fit", just like a standard crown race. I used a piece of PVC pipe with id of about 1.5" to push it down, with the help of a rubber mallet

As for my component list, most of them are reused form other builds or both 2nd hand:
  • fork: Fox36 w/ GRIP2 damper. The damper adjustments barely clear the frame even after adding the angle spacer
  • rear shock: Fox dpx2, see my comments above for the mounting hardware
  • drivetrain: SRAM Eagle GX, with SRAM DUB 89/92 pressfit bottom bracket
  • wheelset: Lightcarbon 350MB-AD938-Race, shared with my other frame
  • breakset: Shimano M8200, which I got new at a good price form a seller on Pinkbike. The rotors are generic from Amazon (https://www.amazon.com/gp/product/B082NVF3TD/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1)
  • dropper post: and old Tranzx 31.6x140. I pushed it all the way down the downtube.. and it still might be too high, I need to double check it, but I have not measured the insertion depth
  • saddle: a SDG Radar.. I have no idea of how good or comfortable it is, I got it at a discount because my other SGB Bel Air failed, but I have to say that I like a lot my WTB Volt on the other bike
  • stem and Carbon Handlebar: inexpensive from Amazon (https://www.amazon.com/gp/product/B0916YJ81R/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 and https://www.amazon.com/gp/product/B07JPF4T71/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1)
  • headset and Sitclamp: I used the one that came with the frame. The frame also came with 4 cable hole plugs, for the larger holes by the bottom of the downtube. They are rubber, not easy to install. Not sure if they will hold
  • missing: chainstay (and maybe downtube) protection. I have something that might work, but I haven't tried to install it yet.

I hope this is helpful to others..

Short answer - 22.2 and have some shims.  We don't have multiple samples of the linkage reporting dimensions...yet.  Also, one person will test the Santa Cruz linkage - if it works the 30mm front and rear roller bearings become options.

If going the 22.2 option BK5864 is a part that has a needle bearing.  Bikeinn had some in stock at the time of this posting.

My measurement was 22.86, which you can find, for example here https://www.amazon.com/Shock-Mount-Hardware-Washer-M8x22-86mm/dp/B08HR4YLMY
I used 22.2 + shims, because that's what I had.

I should have had my frame today too but USPS delivered it to the wrong address! it even required a signature but that wasnt even enough to prevent an incorrect delivery.  i really hope they can recover it but seeing as i havent heard back from them and its already 7pm here, i fear the worst.

Eddy,

There are some really nice and honest people. A lady with two young babies just dropped off the box . It was delivered to her house by mistake and she went through the trouble to make sure it was delivered correctly  thank you for all your help and sorry for bothering  you! I have thr frame now.

Jon

The frame received, thanks.

Re: The Shiny New AM831 Group Buy (A) Thread! Got the frame today. I have to go out so will go over it better later but it looks good so far. It's a large painted frame and with just the der hanger it weighs 2435g.

I stuck the rear shock in since I pulled the shipping rod to weigh it, and with the 22.2mm rear mounting hardware I was able to put one 0.5mm shim in and it was a pretty tight fit and I can't feel any "slop" or play even before tightening the bolt.

I also slid the Suntour Auron fork in with the bearings just to get an idea on clearance, and one side misses and the other side with dampening knobs just barely hits. A couple 2 or 3 mm will probably be all it needs. But I imagine it will depend on the fork and some will clear a large frame.

I will work on it later and add any thoughts or issues I come across

Edit: spelling

Can someone post the exact specs for a crown race spacer that worked for them?

Currently available options that will work without a special bearing:
3mm race
https://canecreek.com/product/3mm-52-40mm-alloy-crown-race-baa0855k/
6mm race
https://canecreek.com/product/6mm-52-40mm-alloy-crown-race-baa1078k/
10mm -0.5 degree race
https://reverse-components.com/en/products/05%C2%B0-angle-spacer-tapered-forks

Alternatively, use a downtube protector as a bump stop :) :
https://www.ridewrap.ca/products/shuttle-armor/

Specialized used to make a tall race for stumpjumpers and I think Hope and Chris King had some sort of race spacer available.  Not sure if any of those wold work right without a specific headset lower to match.  Anyway, don't have the frame yet but just throwing out the available offerings.  There are probably others available on Ali or Amazon but for under $20 USD I picked up the 3mm Cane Creek to match the headset.  I'll just add the downtube protector if it still hits, I'm not planning on doing bar spins and I move the back end on tight turns and switchbacks.

Re: The Shiny New AM831 Group Buy (A) Thread! Received my frame today. Quite a bit of shipping damage on the box but the frame seems unscathed.

I ended up purchasing the frame from Topfire, not Haidelai like most of you. I thought they'd be a bit faster after talking to someone else on another forum and their own statements - I was wrong.

Furthermore, they shipped the frame without anything in the way of spacers where the shock was meant to be - the frame was free to slam in to itself over and over on the way here - fortunately doesn't show.

They also sent literally no hardware other than what I requested (and was charged for) specifically - a rear axle and hanger. I guess I'll need to source everything else from a SC dealer and hope it fits?  The other two full sus bikes I've purchased (from different Chinese manufacturers) at least had like... some hardware...

I also asked for a RAW frame, unpainted - which they agreed initially.  They informed me when it was ready to ship (like 9 months later) that they weren't going to do that - it was coming matte black whether I like it or not.

Between this and their poor organization (they sent a message saying I had to pay more for shipping if I wanted a rush shipment and no duties, and then realized they were looking at the wrong country) I'd HIGHLY recommend avoiding them and going with Haideli. I know I should have. I sure hope that I never have any further issues with this, I think I'd be completely on my own.

Edit: Can someone else measure the thread pitch and length of the included axle? I didn't actually get one despite paying for one. Stick with Eddie guys =/
