Re: cybrsrce AM831 build I just got my frame. Assured by Eddy that the rear triangle was not an issue. Even asked him to double check. The rear triangle is so sloppy it’s a joke. Not even close to okay. I would look elsewhere. Unless you love the thrill of the gamble or the challenge of an engineering project.  Frame looks badass though!  Might end up being good if I can figure it out.

Re: cybrsrce AM831 build I ended up cutting my own nylon washer to fit despite having access to 3D printer.  Determined with my friend who is a mechanical engineer in fabrication and production that the nylon is better for this application than the material that would be used in the 3D printer.  We are going to order nylon washers in the exact measurements from a company he sources from. The spacers are going to have to serve as bushings because of a design flaw with this frame. If there is not pressure on the carbon pushing the bearings on to the upper link, you are relying on the strength of the bearings bond with the upper link to provide stability (not good). Because you need pressure on the carbon of the upper link and this link needs to pivot, it is essential in order to prevent wear and to not bind the suspension that the material used can be low friction.  I think if the bearings were pressed from the outside, this frame would work very well.

Re: cybrsrce AM831 build Eddy told me “all frames have some flex, it is fine” paraphrasing but don’t get your hopes up.

Re: cybrsrce AM831 build No one really has a way to resolve it yet. There are some good ideas out there but they will require some machined parts.  Bushings can tighten it up but not looking like a very acceptable solution.

Re: The Shiny New AM831 Group Buy (A) Thread! I think the new link is best case scenario.

Re: The Shiny New AM831 Group Buy (A) Thread! I got the washer at the hardware store and got to work with some scissors to trim the outer diameter

Re: The Shiny New AM831 Group Buy (A) Thread! Mine rides very well with the 1mm nylon spacer/bushing. I am however inspecting multiple times throughout the ride for slop and the bolts coming loose. No reputable company would ever design a bike like this expecting not to have problems eventually.  It is going to wear down at some point. Keeping track of miles till failure. We may yet get a solid fix thanks to JJJ but no one should buy this frame until the issue is resolved from the factory.  There are too many good options out there to be buying this very flawed frame.  They should actually stop selling it until issue is resolved.

Re: The Shiny New AM831 Group Buy (A) Thread! It’s gonna stick out a little but not too bad. Honestly at this point does it matter much what it looks like?  Bearings are like 4mm thick.  Recess in carbon like 2mm. Probably sticking out 4 mm at most with bolts. A solid fix would be amazing.

Re: The Shiny New AM831 Group Buy (A) Thread! For sure still going to get the bolts from JJJ too. No way we should leave him hanging with the bill after all the work. Honestly at this point, I really want to see how well it works just because I have been so invested in this problem!

Re: The Shiny New AM831 Group Buy (A) Thread! My washers keeping it rideable but too much flex still. Hard turns flex the tire into the seat and chain stays. Way more movement than my YT.
