Those  are all great choices.  i have had Shimano hubs for years and have just gotten used to the cup and cone thing.  gives me one extra thing to fart around with.  here are some pics of the wheels with tires and some measurements of the tire widths.  i have tubes in them at the moment and they are at about 35psi. i am hoping to stretch them out as much as possible before i put the inserts in and set them up tubeless.

I’ll be curious to see another measurement when you have those set up tubeless at that same kind of pressure…pros are running several PSI higher than non-radials so for me I’m guessing mid 30s in the rear and 30 front.

I’ve ordered an Albert Gravity 2.6 to test tire clearance in the rear. NP says 2.5 but that’s with generous mud clearance and probably the shortest (440mm) rear axle flip chip position. Maybe the 2.6 will be fine at 445. If only the 2.5 really fits, I’m not sure what I’ll do. Different tire sizes front and rear have always felt weird to me, but what I want is more like 2.55 not 2.45.

Tire clearance is one of the gambles I took with the Dissent. On the 1286 you can definitely fit 2.6s with room to spare. I’ve always run 2.6 Hans Dampfs on my 1266 (that are really closer to 2.7) and would only consider switching it to the Alberts if I’m really happy with them on the Dissent.

I will get some measurements once I convert the wheels over.  Did you see that Nuke proof is alive again. You may snagged a frame at just the right time.  I had reached out to DIY Carbon about my frame since we are coming up on 30 days and I had not heard anything.  Long story short, the price they were charging was for the non-UDH version which was actually the Dissent frame. If I wanted the 1286 frame, I had to pay another $200.  They said the shock was a different size on the non-UDH frame and since I didn't want to have to deal with the shock issue, I paid the extra money.  Hopefully they can ship quickly now. We just got 11" of snow so not like I can get out any time soon but I want to be able  fondle the bike in my office.  Hahahah. 

Have you received the Dissent frame yet?

That’s weird since the 1286 and Dissent both use 250x75, and Carbonda has the Dissent priced higher than the 1286 not lower. I do worry about replacing stuff like the flip chip integrated hanger (even with a new company taking over) so UDH is another area where I think the 1286 is a safer bet.

Fingers crossed you don’t have any more complications from them, and they can actually get you a 1286 sooner than Carbonda’s “maybe April” timeline.

My Dissent arrived over a month ago, it’s been at my LBS/wheelbuilder for three weeks having a few steps done for me like installing the reach-adjust headset and Hayes Dominions. I think they had to order the special Hayes bleed kits and such before they could finish it. Soon it will just need wheels, and I’m starting to order the parts for those.

I thought I’d have a build thread up by now but the first round of work at the LBS is taking longer than expected. In the meantime I have the FR541 rims and GRIP X2 damper for the Fox 40. Just need to get the hubs and have the wheel builds started which will probably take a few more weeks.

I thought that the dissent had a 250x75 shock and was surprised when they said it was a different size.  I am guessing they just mis-spoke.  too late now though.  Can't wait to see your new rig.  I am hoping the weather here turns warm real quick so I can get mine out ASAP once it arrives.

So i have ordered the frame from DIY Carbon.  i am still waiting on the frame to ship.  there was some confusion initially so that delayed things.  i actually reached out earlier today to see where things are at.  hopefully it has been shipped and i can get to building.

UPDATE:  So i have the frame.  took a bit to ship but it only took 2 days to actually travel which was incredible to watch on the tracking website.  My plan was to do a custom paint job with a white to black fade.  got the first coat down and then when i painted the second coat, 50% of the frame went crinkly on me.  So i spent a day trying to clean it all off and sand it back down.  so new plans are to just go all black with some color splotched on there.

But i am too impatient so i quickly through all the parts on and took some pics just to see what this beast will look like.  The frame has guide tubes for the cable routing so that makes this super easy to install.  Also the inside is super clean looking.  i don't have a boar scope or anything but looking in the head tube and feeling in the BB shell, all looks good.  All the mating surfaces look to have been faces.  headset cups lined up perfectly and BB threaded in super smooth.  no issue with the BB threads at all.

Looking good! One thing that surprises me is that pictures of other FM-1286s make it look like the rear triangle is basically the same as the 1266 but yours looks noticeably different: some differences in the details of the shape but in particular it looks vertically shorter…more like the super compact swingarm of the Nukeproof Dissent.

Which reminds me I need to hurry up and make my Dissent build thread, now that it’s close to dialed…made a bunch of tweaks recently after a few sessions at Highland Bike Park, installed a 2026 X2 shock and tried out the progression adjustment (went back to 21% since 28% was too mushy off the top and sucked the life out of jumps; added spacers and might try the round 25% pivot axle at some point since braking bumps are harsh at 21%).

Can’t wait until you have your build finished up so we can get some ride reports! Looks like it’s going to be a real beast.
