It looks like a zerk fitting. It could just be screwed in to a mounting point to fill the hole/troll us. The only thing I can think of would be a mounting point for a data acquisition device or some sort of electronic control on the spring side.

Unless it's using a cartridge spring it makes no sense to have a bleed valve up there.

I also remember Gee Atherton using an ultra short stem years ago, only to crash a lot and go back to normal stems short after.

You know it's something riders won't mess with when even the guy known for having a ridiculously high stack (Dak) runs a stem that roughly matches his offset. 

To me it seems like there's absolutely nothing to be gained from really short stems.

Hasn’t it been shown several times that Dak’s bar height is actually quite normal (even lower) compared to the other bikes in the WC?  It’s just that the Mondraker starts off with a very low stack height. I’m sure it was here or PB where they actually went around and measured them and it was average.

Not including sales tax always seems like a dumb thing to do. At least to everyone else in the world. 

What you see is what you pay, that makes more sense.

In the US sales tax varies from locale to locale. 

If I buy something where I'm at the tax (local plus state plus federal) might be say 10 percent but if I go over to somewhere else it might be 9 percent.

When I buy online tax is calculated for the zip code of my billing address so the tax will still vary by a couple of a percent depending on where I'm at.

Because of that it hard to get used to other places like the EU where VAT is just there but doesn't vary.

Like the metric system it just makes more sense...smh.

The bar height from the axle is, yes, but he also has his BB set lower than nearly everyone else. The stack:body height ratio for Dak is more akin to the Women (and Jacko) than the other riders of a similar height to him. Regardless of short head tubes and stuff he still has a very unique setup that puts him in a more upright position than anyone else his size.

I was going to say the same thing. 

Jackson gets even more upright by riding a larger bike in relation to his body size. His bars look super wide if you look at how little bend he has in his elbows, but it obviously works 

Dak is riding a smaller bike in relation to his size.

Dak is larger but both are riding roughly similar sized bikes. Add in the low stack of the Mondraker and that's how you end up with the big riser bars.

I think Jackson is on a medium these days. Seems that would be the right size not a size up for him? 

Would love so see someone create a database comparison with riders height and bike dimensions.

He might be. I had it in my head he was on a large, but that's probably a few years old. It stuck in my head because it was a size up from what I thought he'd ride.

Totally agree. Having a proper database with rider stats like height, weight, etc. would be super interesting, just like they do in the road cycling scene.

gentle reminder that MTB design is often based around a medium/ML size, jackson is like the perfect size for it. 
He stands very upright and this is hard to replicate for taller riders, to be in correct ratio for riders over 6ft etc the bike would be so long it would be useless everywhere except for straight lines. including a much longer fork and a very tall frame.(this tall and long theory Brian keeps jerking off about is great for a DH bike, But for anything else. forget it.)

For Normal people riding normal trails, we need to be looking at what EDR riders are using, within reason.

Are you telling me that Jackson Goldstone isn't his real name, and that he's actually called "John Mountainbike"????

Dak is not really on a small bike his reach is north of 490mm

See Paul Aston for experiments in getting the same/similar ratios for taller guys. 

As a guy that is 182cm tall riding a trail bike with 1300mm wheelbase on plenty of janky right Shore trails I would say your thoughts on wheelbase are wrong. Do I want to go longer? Not for a 160mm trail bike, but for longer travel I certainly would.

There’s no such a thing, they make 1.8 and 2mm

Brand engineers have said They design bikes for the majority... Which is M-M/L range.
as far as Bike Size overal, How many more times do people need to see Good riders using a size down to ride local trails etc.
I've tried getting  a big bike around my Locals and around the country and its just so much work.

But hey, Let your arrogant ego side make you believe physics isnt real.

I get what Paul aston is trying to achieve, but has anyone actually watched his videos and how hard hes actually working to move that bus? - the front wheel would be at the next corner before its finished the previous one -  It's also like watching Brians videos about how good a long rear bike is, while hes laying in the dirt after crashing on a long rear bike lmao.

We are not pinkbike here, stop acting like it.

I agree with you on the thing about what size they design for. Hence why people are asking for longer/proportional chainstays. 

I had trouble with heavier, longer bikes until I got stronger and better at riding. Also, those “big” bikes might have just been really unbalanced!

Sizing down is awesome when you’re on a large that has too long of a front center (also reaches were way too long for a while.) sizing down says more about imbalanced design and a suboptimal riding position than it does about wheelbases.

No need for name calling btw.

Not even touching the rest of your points. I don’t always disagree with you but that paragraph about Aston and Cahal is comedy.

Overall you’re missing the entire idea a lot of us are excited about: when a bike is balanced it doesn’t feel big. When you can ride centered in the bike you can ride the bike so much more intuitively and fluidly. You don’t have to agree but we don’t have many examples of bikes built like this (especially in L and XL sizes…) so most of our experiences on other bikes won’t really apply.

By this logic, we'd be on bikes with wheelbases of 1000mm. But we're not, we're pushing 1300mm in a lot of bikes, and they still go round corners just fine on trails we were riding 20+ years ago.

I dunno, 2.5 lbs between Stumpjumper Carbon an alloy is pretty damn noticeable. If I’m the average stumpy buyer I’d much rather have nx on a carbon frame than gx on a alloy frame. Especially since derailleurs wear out/break and I can just get a GX at that point. 

I don't think I've seen that much difference in weight if the only difference is just the frame material..

no, ride one with long cs, he is on to something 

 

and edr riders are often on smaller frames to be able to react faster, not a role model
