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.

 

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

Lol at the level of confidence combined with the level of incorrectness. 

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.

My bad, confused with TRP 2.3’s I have on another bike — which have also been less prone to warping.

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

Conspiracy Theory Hot Take -  Now that SRAM owns O-chain will Non-SRAM sponsored athletes be asked by their drivetrain sponsors not to run them?  Or will mechanics just get out the Sharpie?

If I was a betting man, Id put my money on the part where Sram is going to make the product only work with their cranks anyways. So sharpie kickback hubs may be the easier option here.

Level of Future has released a website that goes into more info on their Flexstab bars: https://leveloffuture.com/

Not much info on availability for the public. I've reached out, these may save riding for me, so I'm pretty anxious to get more info on when they'll be available. They look really promising for people with wrist/hand/elbow problems.

Is there a plain image of the bars anywhere? I tried finding it on their website but on mobile that thing is a nightmare.

https://www.instagram.com/level_of_future/# has lots of photos/videos on them. Their website just went live a few days ago so it needs work - for instance the contact page doesn't seem to work and the email address on the English site bounces. Will just have to be patient and wait for them to catch up.

I've reached out a few different ways and haven't heard back yet on availability. It's really hard to gauge their intent - the PB video mentions they were looking to sell the technology/license it for others to manufacture, but some of their content seems to indicate they will be making them themselves and selling them (or both). AFAIK they haven't publicly stated any intention to release to the public or make them generally available yet, but most of their posting is in Polish so it may be I missed it.

I've reached out to them a few different ways to try and get an answer, these could be game changing for me and possibly save riding for me altogether, so I'm really anxious to get more info but so far haven't gotten a reply.

A sales manager at Shimano just built up a Digit Ring and sent me some photos.

It has an unusual Pro Tharsis handlebar which I've not seen any reporting on*. I gets fatter each side of the stem, and it's not round each side of the stem either. A fatter diameter normally indicates a stiffer structure which I'd normally be wary of, but I'm told the shaping makes this is as compliant as the OneUp handlebar. It does look pretty sick.

Both the bar and stem have cable-tourism routing - but they don't seem to be noticeable on my cable-into-the-downtube frame.

I am not upset about the weight and nowhere was I complaining. I simply stated what I built and the weight. It’s about 2 lbs heavier than the carbon frames, that’s what the conversation topic was about.

New version of the PRO Tharsis line, the EVO model I b'lieve. The rumor site had a shpiel on it back in June. Sorry to say it is not named Stab.

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.

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

But Dak is a good bit larger (4-5" taller?) than Jackson. That was the point I was trying to make. 

I think they are looking for similar positions but Jackson is getting there on a "more normal" looking setup because he is smaller.

Caliper position makes no difference on suspension at all. Only thing that matters is which link the brake attaches too. 

Very strange looking adapter. Only real differences between adapters are:

- Position: aesthetic and clearance related
- Stiffness: has impacts on vibration and noise

That to me looks like someone is either using some very optimized shapes to control the natural frequency (unlikely) or they are trying to shield the caliper slightly from air/mud/etc.

That's the stock V10.8 brake adapter for 200mm rotors. It allows for the 3 rear axle positions. They also have a 220mm rotor verison.
