Re: Stumpjumper clone Update: The location of the water bottle mounted is way to high. I noticed that right away even without a piggy back shock (which I am going to go with) so I drilled a 1/4" hole 65mm below the bottom screw mount and installed another rivet nut in to the frame. Major improvement. Highly recommend doing this. Paint so far.... Sanded - 600, then 800 -  black primer and then added color effex paint. Looks amazing in the sun light. Decals ordered, then 3-4 coats of clear.

Bottle holder really is too high, but i'm not really comfortable drilling holes in a carbon tubing... Maybe epoxy would help?

Another question, top shock mount is from specialized spec standard 6x20 but this frame has an opening of 21.6. Probably the best thing to do is to machine custom bushing to have a tight fit, right?

It's not something you want to get wrong that's for sure - but not something too difficult either. I have done this many times and I always say, pilot hole first fo you know exactly where your going. I would not recommend epoxy. I would make up a piece of aluminum 140mm long by 10mm wide then 3 holes in the aluminum spaced 65mm apart then that way the bottom hole on your bottle mount will at least be in something see drawing attached...Make sure also to install some felt under the bottom edge so it prevents the plate from slapping on the frame

Re: Stumpjumper clone Really nice build. I'm still quite happy on my P9, but this frame has compatible guards chain stay protectors etc.. Which makes it really nice.

I noticed your Seat Angle is 65 deg, which is a pity, because my long legs will expose that weakness, and It ends up defining the climbing character quite a bit. One can possible take 2-3deg back by sliding the seat forward, but I'm not to keen for that.

Still, nice bike though. Wish they would get the seat tube angles right.

Re: Stumpjumper clone Hi Bos...I think you are looking for the "effective seat angle" which wouldn't be 65 degrees.

If Mousey took a straight edge or a level and lined it up from the center of the bottom bracket to the seat mount...and then put his angle finder on that straight edge...you would get the effective seat angle.

Edit - seat would need to be at the normal riding position...not the slammed down dropper post position.

Re: Stumpjumper clone Just to update anyone who in interested...I did finally get the frame.  Took approx. 6 weeks from day of payment to delivery.  There was some drama with USPS at the end where the postman refused to deliver it to my home and wanted me to go sign for it at the post office.  The shipping carton was severely crushed and he did not want to take responsibility.  The post office would not allow me to open and inspect the contents before signing for the parcel.  This is their policy..."no inspections allowed until you sign".  Thankfully...the frame inside was not damaged.

Everything was included...Headset, QR Seatpost Clamp, Rear Derailleur, Chain Guide and Rear Axle.  The frame was pre-routed with the plastic lines to pull both the shifter cable and rear brake hose thru the inside of the frame.

Quality looks good...they are incorrectly listing the Bottom Bracket width at 63mm...it is 73mm.  There is one minor manufacturing flaw that I will have to resolve.  One of the bearing bores (seat stay inside non-drive side horstlink) is just a couple thousands too large...so the bearing wiggles a bit...it does not fall out.  I will try some carefully placed red Permatex thread lock to see if that solves the problem.  As far as a warranty claim goes...AWST Cycling Tatics is still not showing any available product on their AliExpress store...so it remains to be determined if they are no longer selling under that name.  I did some more digging and I think they may be AllStar Bicycle.  The other 11 bearings fit tight.  They ship the frame with metal shielded bearings...so I am swapping them for ones with rubber seals so I can clean an re-grease when needed. 

Frame Weight "M":
Frame (with just the Derailleur Hanger attached) = 1,920 grams
Chain Guide = 49 grams
Headset Bearings (excluding that metal expansion plug) = 76 grams
QR Seatpost Clamp = 59 grams
Rear Axle = 44 grams
Total = 2,148 grams 8)

Re: Stumpjumper clone Or if you want the actual part...you need to order it from a Specialized Dealer...they are not available on line....cost me $5

Re: Stumpjumper clone So couple of photos of the finished build per say...

Things still to be done are:

1. Cut down the front rear shock bolt.
2. Remove bushes from rear shock so flip chip fits.

In both cases thanks @swuw2331

Other all good, rides well but will take some getting used to coming from a 26er... especially the slower but more nervous steering resulting from the bigger front wheel and shorter stem.

Re: Stumpjumper clone So here is my finished product

Re: Stumpjumper clone Hello everyone!
Assembled a bike on a frame from AirWolf. I waited a very long time for production (one and a half months), and then another 3.5 weeks of delivery. I turned to him because of the promises to make any color (I wanted the blue SJ 2019 Expert), but it turned out that he can only do a few templates. He applies the logo and text with a sticker, not under the varnish.
The terrible quality of the metal inside the thread in the frame, one bolt turned (the frame was sent to me disassembled due to the restrictions of the postal service on the dimensions of the parcel), but at a risk, I put it on the blue thread lock. Perhaps I will order a new bolt from the turner, since the thread in the frame is deep, and the screw (similar to the original one) uses only ~ 7mm of it.
I took a RockShox rear shock, ordered an original flip chip, and here is the first failure - it does not fit the Chinese link (EXTENSION). The height of the flip chip is about 16mm, and the groove in the link is 13.7mm. Using physical force, I inserted a shock absorber into the link, but it looks unsafe. I ordered a 14mm bushing for an 8mm bolt. The original bolt for the upper mounting of the shock absorber was too long, shortened it by 3mm (this was reported above in the topic). I also ordered a 21.8x6mm top mount bushing, and it fits much better than the included bushing (it got loose). So if you use an RS shock absorber, then order 21.8x6 and 14x8 bushings right away, you will save a lot of nerves. I would be grateful if you could recommend FOX hubs (I only use RS on my bikes and am not familiar with FOX).
I did not succeed in closing the cable routing hole as in the tips above (with a rubber plug). I sealed the place with a protective film, made a hole in it, and pulled the cables through them.
The original chain guard fit perfectly, as did the axle. I also used another clamp, the Chinese one is huge (and heavy).
Depth for seat post approx. 170-175mm (frame size L).

After assembly, as in the photo (without bottle), the weight came out 12.85kg
The RS Super Deluxe shock has a very large reservoir can, which interferes with a 750mm bottle with a cap. I'm thinking of putting Fox on, it has a smaller tank :)

P.S. Sorry for my english (google) :)

Re: Stumpjumper clone I buy such frame in L size and white color from another aliexpress seller.
Briefly:
This is high modulus carbon frame like original SJ MY19.
But... i kill tread on one rear bolt (M12 body and M11x1 tread) - make new from В95Т1 alloy on home lathe.
Top eye shock M6x1 bolt was 90 degree champfer, but frame (as original) have 120 degree champfer... make new from В95Т1 alloy on home lathe.
There is no holes for place hosings in middle tube (as in original manual), but SWAT hile is absent and all housing plased in bottom tube.
I buy dropper OneUp v2 180mm. Frame have slight problem to place dropper more than 17cm, but i cut 1mm from diameter of dropper ass and get 22 cm!
Original bolts have rubber seal, i simple print TPU seal on printer.
Complect seat post clamp have ~40.5mm diameter instead 38.6mm, buy right item on aliexpress.
Original flipchip have big size and you need mill additional space in yoke if you whant it. As i understand that tight flipchip block bottom eye frop any rotation. But default china yoke set in "XC" position - not bad choice.

Geometry precisely mathed to info by aliexpress lots! But have no such geometries in linkage web base. See attached *.itx file for linkageX3 software.
For this frame maximum drive chain about 32T, but pedal efficiency at this 90..80%, if you move gravity mass to front - efficiency increase. I think that 28T (or may be 26T oval) and 9..42T cog wery good variant - for 28T drive antisquat about 100..110%.

Positives:
$800
Nice look.
Light weight (may be it good moment).
Compatible with  "old" common 210x55 shox - simple to find in sale section.

Negatives:
No SWAT! $(
No frame guards (use 3d printer...)
Decals above paint lyers. I use oraguard anti stone TPU film.
Frame have very thin wall in BB link region - may be this is normal, but...
