Re: The Shiny New AM831 Group Buy (A) Thread!
By the way, how did you guys manage to route the lines through the rear triangle? Using an ebay knock off of the Park tool internal routing kit. https://www.ebay.com/itm/Bike-Bicycle-Internal-Inner-Brake-Shift-Cable-Frame-Guide-Routing-Tool-Kit-Set-/133643298200?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=711-127632-2357-0 September 28, 2021, 01:20:19 PM |

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: The Shiny New AM831 Group Buy (A) Thread!
It is worth showing the link assembly issues with pictures rather than just words to get the message better across, so I've drawn some (not to scale, dimensions exaggerated, showing the principles). This is the 831 assembly of the upper link to one of the rear triangle eyelets, as far as I could make it out. Grey is the aluminum link, black the carbon triangle, blue the ball bearing and pink the screw. The screw presses the inner race of the bearing against the link, so the screw and inner race are one piece with the link. There is some clearance between the screw head and the triangle so that the parts can rotate with respect to each other. This assembly would be alright if the two eyelets of the triangle (only one shown) were perfectly rigid relative to each other, but that is not the case. So, what prevents the outer bearing from sliding out of the triangle eyelet (to the left) is in practice only the press force of the outer bearing race in the eyelet, as Maffly stated. Inevitably, when the triangle is submitted to lateral forces, the bearing will end up sliding to this position, where the eyelet contacts the screw head, and rubs against it as the triangle and link rotate relative to each other. After a while, clearance may build up between the outer race and the eyelet, whereby the bearing will move freely in and out... The rubbing with the screw head will cause wear and potentially loosen the screw... The situation wouldn't be improved if the bearing were pressed from the outside. The bearings should be in the link, not the triangle, as per the SC assembly shown below. Yellow is a tube for taking up some of the axial force exerted on the bearings by the screw. Here, the bearings are mounted in the link and rely on the rigidity of the link between the two eyelets. The bearings cannot slide out. Dammit, the 831 link and triangle need to be redesigned!! A not too drastic redesign would be to provide something for keeping the bearing in the eyelet, such as a retainer ring. What about the assembly of the lower link to the triangle? I haven't looked close at that yet. November 29, 2021, 04:10:44 AM |

Re: The Shiny New AM831 Group Buy (A) Thread!
Back again with some comments on the upper link bearing mount. On the left, the actual mount, to scale. On the right, the nearest correct way to do it - an elastic retainer ring holding the bearing in its recess. This is a suggested (IMHO good) correction for the existing frames, to scale, using a standard pair of 6703 bearings that fit in the recesses for the bolt heads. Needs a new pair of bolts as drawn - I have a mechanic workshop in the neighborhood, and will check if they can do this and for how much. Probably cheaper if I can order a certain number of pairs. A minor issue is the tolerance of the carbon width (approx. 3mm) between the two bearings, and whether the inner race of the new bearing will rub against the carbon. I've ordered a pair of 6703s to experiment with. December 01, 2021, 04:06:13 AM |

Re: The Shiny New AM831 Group Buy (A) Thread!
Eddy. 220 dollars is a great price for a crash replacement. If you send me a perfectly functional bike and I crack it by crashing into a big rock, that is on me and I am happy to pay to fix it. If you send me a bike with a clearly documented flaw that is not capable of basic trail riding without modifications then that is on the company. I even emailed you about the issue when you still had the frame. You assured me that my frame was all good with no problems and that the issue was fixed. You may get away with charging for this, but the trust in your company will take a huge hit. Haideli may save a few thousand in the short term by not taking responsibility for their mistake (deception?), but will probably lose in the long run by losing all consumer trust. I understand that you are probably not calling the shots but this is bad bad business. No one should by buying frames from Haideli until they step up and take care of all of us who trusted them with our business.

Re: Stumpjumper clone
Just leaving this here for future buyers... So I have been in communication with Airwolf regarding the poor Quality of their bolts that they use. They wanted to get out of sending me new bolts since they see it as Consumables, and the warranty only covers the frame, even though I only received the Frame in November and the bolts are already worn out. So in my opinion they will use anything to try and get out of warranty claim. I love the Stumpjumper frame itself but I do think you will need to think twice before ordering from Airwolf. Perhaps another manufacturer that has better service would be a better option, else I would recommend going for another frame as I doubt if anything should go wrong with this frame that you will get assistance from Airwolf. I needed to threaten them with registering the transaction as fraudulent with my credit card company due to the frame being unusable without the bolts. They have agreed to send new bolts now, for me it was about the principle of the matter of supply poor quality bolts, I will be opting for the Specialized bolts kit and letting something machine the other bolt for me that needs Right hand thread as well.

Re: Those with AM831 built, are you happy with it if not including flexing issue?
pretty much any vendor is going to be able to get you a nice cobalt blue if you ask. yeah i know...just that I already have it. I've painted cars before too so I could prob do it myself if I got a primered or plain version for cheaper. January 03, 2022, 06:14:17 PM |

Re: FM1002 / FM1166 - 150mm frame
For anyone following along at home, the frame arrived just before Xmas (3wks postage to Australia). The finished quality of the frame and paint job is great. Paint near the bearing is generally good, only looks like one spot where the paint might flake off, time will tell. The only thing I don’t like is the top cover for the headset but you can’t really complain for $15. Overall I’m quite impressed with the whole experience. I know we are "down under" but that bike really is gravity defying.  January 04, 2022, 05:14:37 AM |

Re: The Shiny New AM831 Group Buy (A) Thread!
Whilst I completely understand this sentiment, it probably wouldn't do much to help the numerous other members of this forum that are trying to get Haideli to step up and do the right thing. January 06, 2022, 04:17:09 PM |
