I don't have any idea when it's going to be released, but a friend was at a shop who sells them and has seen it (pics, geo charts, etc). He said he's pissed he sold his v1 as v2 looks like it's quite a bit different. Said sizing is weird (med is shorter than v1 and large is longer?). Said they've switched to a four bar design to be a pedal better, but possibly at the cost of dh performance. 

I don't know anything about anything, but he seemed pretty bummed about it. I guess we'll see?

That's funny because I've seen the geo charts and it looks like it fixes a lot of the issues I had with the current bike. Does your friend want to buy my V1 dreadnought? 

Not going to leak too much but I really though the geo moved it in positive ways, for sure takes cues off their supernought on a lot of things. 

I've seen it and it's basically a supernought with less travel (swap drop outs for mullet etc) and some sick paint jobs.

I don’t know but I suspect it will be coming sooner than Forbidden wanted it to because of the leak.

Re the Dreadnought V2, any hints as to how much rear travel?

Why would you want anything different?

If more front-end stiffness is what you want; a 20mm axle wouldn't really help with that. If they wanted to increase stiffness, they would have needed to go to a keyed axle to really tie the stanchions together. There's no point in just making the axle bigger in diameter. It would achieve nothing.

The "axle" isn't really an axle anyways. It bears no radial load. It's a basically just a big draw bolt. Its only job is to clamp the hub into the drop-outs with substantial pressure. A 15mm axle can do that job just as well as a 20mm.

Yup! If there was any benefit to using a different axle size they would have done it. People should listen to the inside line episode, its goes over all of those tech details, and they really tested every idea during the development process. Including the keyed stanchions, which they had basically assumed would be needed and turns out......you do not. Its super interesting!

Ya that weight is tough. I get its coil, but my EXT might as well be coil and its significantly lighter. I'm willing to bet a Zeb or 38 with a coil conversion is significantly lighter too. 

As a Smashpot owner, the weight with a reasonable spring rate will be very close the push nine.

I haven't listened to the whole podcast yet, but I skimmed through it. What I want to know is how they addressed yaw-ing of the two tubes. 

A key issue of upside down forks in MTB is that because we use one side for a spring and one for a damper the amount of force required on each side to compress the same amount is quite different. This means the wheel and fork yaws (twists) under load. 

It happens on "right side up forks" a bit too even with their one piece lowers. Put 2 o-rings, one on each leg and notice how they never quite match up the amount of travel they use. 

I've done the same thing on a Dorado and it's quite significant at times. 

Moto doesn't have this issue as each leg houses a spring and damper unit, so the forces for each side equal.

I don't think both legs have spring and damper in MX forks:

Some moto forks do have springs in both sides but certainly not all. Some of the WP forks have an air spring on the left side and damper on the right. Other WP forks have springs on both sides. Just depends on the application.

I hope sizing isn't weird. Current reach at 462mm is pretty good for a medium. I'm 5'10 and usually between sizes so hopefully medium doesn't shrink.. 

Is there such a thing as being "between" two sizes when it comes to bikes?

Like I get a short sizes, (I like to think I'm a Large, but then I put on a shirt and think, damn it, did this shirt shrink...)

I'm 5 10 as well, and figure I'm pretty square as a medium.  Lots of manufacture info puts me in a Large, but that doesnt "feel" right.  My Medium Fugee (445 reach) and medium Spire (460 reach) "feel" perfect, due to the different seat angles on the climbs, and the pace that im trucking down.

Its never perfect all the time, and wouldnt be on a large either, so I try to optimize for the riding I prefer with each bike and terrain

My zeb 29 @170 with a smashpot (50lb spring) weighs 2900g.  The push fork is not heavy for what it is imo.

@Onawalk it's kinda like reach is not the right metric for bike sizing if you have to pedal it 😂

Moto doesn't have this issue as each leg houses a spring and damper unit, so the forces for each side equal. 

I don't know if they did anything about that specifically or not, again they might have found it doesn't matter? I was thinking about that recently and people seemed to think the fork would bind as each leg tried to move differently, but I guess if they are moving separately they aren't binding so whats the problem? If you look through Push's instagram there are photos of running 2 position sensors (one on each leg) so they would be able to tell if there was a negative effect there. 

 

A lot of moto forks have run separate spring & damper legs over the years - the racetech suspension bible (first published in the 90's) points them out and notes that there didn't seem to be any problems with it

Formula put out some preproduction DC Selvas a couple of years ago, and rumor has it they'll be released this year. Weight was in the 2.3kg range, Chris Porter from Geometron loved his.

Or maybe he finally realised that no fork with gold or orange on it belongs anywhere near a mountain bike!

Pretty brutal review of the Mavens. I saw other reviews that mentioned the lever pull, but not to this extent.
