Lol. Just enjoy the damn thing! Good to see someone actually building this up. I gave up way to easy lol.

No, you will need to source proper bushings or have them fabricated. Bushings that came with the frame were more like place holders and did not fit the rockshox deluxe shock I was planning on using. My frame came with a hanger and a headset only. It did not even have grommets around the internal cable routing holes.

My frame from Airwolf had a UHD, or at least a close copy.

« on: June 04, 2023, 08:52:45 PM »My guess would be because of your Brain rear triangle. But if not matching up to the OEM, then that means Airwolf doesn’t use a 1:1. AWST does, they use the EVO rear, 1:1.
I don't know about this AWST seller, seems like all of them tell you what you want to hear. Get it, and let us know what you think. Hopefully it works for you. What are you planning to run on the front (travel)?

Putting a 120 on the front of the regular epic will be make the seat tube angle slacker.

« on: June 04, 2023, 08:42:17 PM »Yes, we are on the same page. There is no brain involved on the frame I am personally looking at from AWST. This is the one is as seen from post #20 The seller confirmed his rear Brain triangle and EVO triangles are 1:1. It is slightly different from your experience with Airwolf.
I asked people on the EPIC Evo Facebook page to give some rough measurements of the rear triangle, they they did not match up at all to that of the regular Epic or to what I received from Airwolf.

« on: June 02, 2023, 04:51:14 AM »My friend, AWST sells 1:1 EVO front and rear triangles, but the linkage and yoke is a copy of the geo of the Epic w/ brain. Idk why, probably less carbon strength needed for that leverage ratio, either way i think i’m getting it.
Linkage layout is what increases the leverage ratio on the epic. To accommodate the new linkage, rear triangles are different on the epic vs Evo. Front triangles are identical.

« on: May 21, 2023, 06:10:11 AM »this bushings or bearings? (marked on the photo)
I am 99% sure there were bearings everywhere. I don't remember seeing any bushings, but its been a while. What I do remember 100% is that the linkage arrangement matched that of the regular epic, except some bearing sizes were different. So basically if the real epic has a bearing there, this frame would have one there as well.

Not bad at all if you want a 100/100 XC bike. It's a regular epic frame. I wanted more travel.....I wanted the epic evo.

« on: May 19, 2023, 10:40:02 AM »does anyone have feedback after long term use?
I ended up returning the frame back to airwolf for a full refund. Definitely want to give them a shout-out for working with me on this.

« on: March 08, 2023, 08:01:21 PM »@wwwru, how are you measuring the chainstay length?
I measured it with the flex stays in the relaxed position, which with the supplied linkage ended up being uncompressed 190mm long shock.
Is that the prototype 3D printed linkage?
The other unknown about this frame is the relaxed position of the flex stays. On the Canyon Lux for example, flex stays are in the relaxed position at sag....approximately. On this frame, with the supplied linkage, flex stays are relaxed at full extension. It makes sense for them to be relaxed at sag, but I can't really confirm that since I only have one bike model to compare it to and there is not much info on the internet.

« on: March 07, 2023, 09:40:09 AM »How much are you getting?
I was getting 435mm, but again, chainstay is hard to measure because it depends on where in the travel you are.

« on: March 07, 2023, 08:57:03 AM »If a new linkage was created for the current rear and front triangle, I wonder how much further you can push the rear triangle out. The Evo seems to push it out 10, 20mm?
From what I remember, I think it's only 5mm.

« on: March 07, 2023, 08:27:06 AM »Oh I was under the impression that even if we get the new linkage, we would need a revised rear triangle.
What makes me think that is
1. On the official specialized replacement part site, the Evo and regular epic have two different rear triangle part numbers. https://support.specialized.com/epic/en/service-maintenance/replacement-parts
2. Logically, the Evo linkage moves the rear triangle back a bit, increasing the leverage ratio. I would think that the angle between the seat stay and chainstay is a bit different to maintain the bike geometry.
I’m only theorizing here.
If it’s only the Evo linkage that’s different. I see it being sold here: https://www.francesconibike.com/en-us/products/ricambio-specialized-shl-my21-epic-evo-shock-link
No, you are correct, the rear triangles are different between the Evo and regular epic. What I am saying is that if they can make an Evo style linkage to work with this rear triangle it would good enough.

« on: March 07, 2023, 08:07:17 AM »Although thinking it through, if i get him the new linkage, he should be able to create a new design with the chainstay length and the seat stay length + new pivot linkage. Is that right?
I am not following your question, but if the supplier can come up with an EVO like linkage (3:1 leverage), I think the frame will work fine with the regular epic rear triangle.
