Sadly this one is not mine, but forum member @sanosan34 shared this yesterday.

Raw carbon, RH2, 600wh, Fox air, #147 (23.2 pounds as delivered: frame, battery, drive system, shock):

Spreadsheet math puts my build at 48.5 pounds if it all adds up right!!

Does the frame only option. Come with brake mounts ?

If not want size will
I need, front and rear ??

Yes, it comes with a rear brake mount. They are specific to whatever size dropouts you have.

Has anyone found a nice storage box (not bag or strap) that mounts to the top tube bottle cage bosses? Something narrow and sleek, large enough for a Tubolito small spare tube, a Dynaplug and a CycPlus Mini Ultra pump?

@digitale your power cord routing is not idea. It should to through the RD mounts. Check @bikedrd pics above your post.

Do you have a 3D printer? I made tool roll out of TPU that holds a CO2, Probike inflator nozzle, Dyna plug pro kit and a tubolito. It's held on with a Daysaver coworker kit's and the rubber strap. Pretty much all I need but water. If you want it I can post my model on printable

whats everyone’s weights and sag on the vivid coil?

I’m 155lbs on rh3
Mine came with 500lb spring and I’m just under 20% sag on that. Ordered a 450lb to try out. Wondering if I actually need 400lb.

Odd because on my amflow I’m on a 525lb spring (ext storia v4) to get 28-30% sag at the shock. Guess the vpp makes a big difference there.
 
When I take all the air out of the shock and compress the linkage fully there's about 10mm of unused travel in LT and about 5mm in ST.

Can someone confirm this is the same on their bike too? Or explain why this would be? What am I missing?

Nice set-up....Getting ready to start building mine...I also went with podium fork...How are you liking it? I was a little concerned with the 180mm rear and 170 front but. 10mm really a big deal? Thx

I'm assuming they're running the rear suspension in the ST/160mm configuration with the 170mm fork.

That’s very odd. Is the rebound knob hitting frame? Or could it be something with the hbo?
 
breakfasttaco93 said:
Rebound knob is off and running no HBO. Bike is progressive enough as is. It's almost like there might be a travel reducer in the shock?

Have you checked this on yours?

Dang that sucks man. Keep us updated. I have not. I have the vivid coil and I just got surgery today so trying not to move haha. I’ll check mine next week now. Hopefully someone else chimes in.

Virtual pivot suspension designs (I.e.VPP) typically require considerably less spring (air pressure or coil spring).
If you think about it it's one of the things that contributes to the excellent weight of the Cresties. Their probably saving a 1/3# just in spring weight.

I'd follow what Troydon recommends, works for me and you'd need way less that 500.

Even at 0 there's still HBO. It's not turned off.

But why would his max travel be different just by changing his lt to st on the linkage if it’s the hbo? I initially thought hbo too, but both would still be the same if it’s hbo stopping the full travel.

Obviously there is still some hydraulic bottom out working saying running fully open HBO.

Still would think you would see full travel happening at full bottom out.

Let all your air out compress your linkage fully and let me know!

Im the same weight and was running a 375lb spring on the 181.1. Running a 400lb spring now on the 181.2 but have yet to test ride.

I’m on a RH2 first time running coil but all my other air shocks (fox & RS) I run stiffer than suggested by apps ~20psi over, my ride weight fluctuates between 170-175 lbs i’m in short travel config @ 27% sag & will try the 400 spring, if i didn't run my air shocks higher I would’ve prob gone directly to 350-375 spring so I’ll try this out & see as i still haven't gotten first dirt yet 😢

I'm 135lbs and run a 350lb spring on my 181.1 with Vivid Coil and also on my 181.2 with Fox DHX2 Coil.
 
Any reason I shouldn’t run the EXT Era V2.1 LT with 190mm travel on my Forge series frame to pair with the EXT Aria rear shock? I can reduce it to 180mm if it feels too tall, but I was originally planning to run 50mm rise bars but will run 35mm rise bars with this 190mm fork.

A little more initial pressure pushing through the HBO, I'm sure there's air still in the negative chamber... too many factors just letting air out. If the concern is rear suspension binding take the shock off to test it. If concern is with the shock let some air out so you know you can fully cycle it with your body weight to get through the HBO.

Yeah I thought more and think it's a combination of the stiff ~4mm bottom out bumper and some HBO working in the last 20% of travel.

Im sure if I hucked to flat with low psi I could get full travel. Been riding hard and still have about 5mm unused travel consistently, though on trails with no mega compressions.

Feel like it's still a bit progressive on an already progressive frame and would like to get in to that last bit of travel more easily so am gonna remove the vol spacer and see how that goes.

No longer think it's a shock or frame thing.

Troydon has recommended running no HBO because of the progression at the end of the travel, you sound like you're on the right path. If you ever have the desire look at Fluid Focus for a custom tune. It's well worth the cost, they're magicians.

Or try coil someday. It's really transforms the suspension.

Running a 450lbs spring at your same weight and it seems perfect!

That's a sweet setup custom setup. Would love to see what it looks like unloaded. I life things to be enclosed, as I've had too many issue where, by the time I need a tube, the tube has deteriorated due to elements.

You’re welcome! I did my first ride with this yesterday on trail mode and for the first time I was forced home not by battery life but actual life (time)!

I used trail mode as well in the power setting. Did 21 miles, 5200 feet and had 25% battery left! The mode provided a great level of assistance and felt very comfortable. I was definitely working a bit more, which I enjoyed, yet it was very much zone two exercise. I still had the turbo setting that I was able to use for steep sections with tons of assistance.

I think I’ll try to use the daily settings next and see how that compares

The extra power is nice but not necessary. Give me range on a lighter platform every time. Having the option to use it if needed is nice though ie turbo and boost.

I must be an imbecile — I briefly looked at the chart and decided there is a page missing, that explains it in layman's terms….
