Geometron wasn't happy about people finding a spot to squeeze a bottle in up front of the shock so they stick a brace in there. 

Any list of what has changed on this one?

Got the pic from the Geometron facebook group. Original poster noted the following changes: lower standover height, straight (not tapered) oversized headtube, additional gussets and UDH compatible. 

Other visible details include internal cable routing and a taller headtube (less spacers under the stem compared to the current G1's in the background)

Taller headtubes/stack feels like the next 'feature' trend that will spread across brands.

I asked the Geometron guys and they didn't say specifics but said they made some geo tweaks. Maybe stack is higher, which would be welcome. That fat head tube will make adjusting reach or head angle via headsets a bit easier. Hopefully they retain the ability to cleanly run fully external cables.

While I want taller/longer headtubes its been the opposite of many brands, they are going smaller because it allows Riders to upsize but then lower the bars.
They will also argue its cheaper(smaller) and stiffer but I disagree about stiffer as On a 105 headtube bike I can feel the extra flex verse a 125 headtube because you have to run the steerer tube much longer where its not supported by the headset/frame

It's a bike being ridden by one of the Canfield guys. I don't think they can build a bike without putting left-field parts on it. Tongue

Just run higher bars with more rise.

Avatar checks out. 

 

(Also yes please, currently running 30mm spacers + 10mm stem rise + 35mm bar rise on a 110mm headtube, which is just silly, maybe I need some Dak Stack bars...).

One thing I recently learned is some stems have a limit on bar rise. Due to excess leverage and flex. 

Basic rule of thumb is run as little spacers as possible to reduce flex in the steerer tube and run taller bars within the limit of your stem spec.

On my new build, I am running an Intend fork with thicker steerer tube walls, and Intend Stiffmaster top cup and Rulezman 15mm fully clamped on stem (HC-V3HD) with 50mm Enve M9 bars.

Doubt they do that. More likely GPS is used to log the position on track where the telemetry data is being recorded.

Oh, data acquisition

Same, only with even more spacers... Can't wait to get my hands on a 55 mm (or more) rise bar.

@chasejj that sounds... stiff. Also, regarding the limit, got more info on that? It's the first time I'm hearing that and it's not intuitive why that would be an issue... A bar is a bar is a bar is a bar? I mean a 20 or a 35 mm rise bar at 810 is going to have about the same leverage as a 55 mm rise bar at 760 mm.

EDIT: scratch that, bar rise has almost no effect on leverage by increasing the distance from the clamping area linearly. Additional torsional loads in the clamp might play a role in things with higher rise bars, but for added leverage bar width is the main driver.

which is what i do but hard to find 40mm Carbon bars similar to Oneups
I also feel like higher rise bars, especially alloy flex more

yes and no, Theres oneup flex and then theres 'sketchy flexy' 
Longer steerer, short headtube and high bars is awfully vague

Is a long steerer and not high bars more vague than high bars and a shorter steerer? 

What is the difference between Oneup flex and sketchy flex? The location of it? Or something else?

I've got some PNW Loam carbon bars at 38mm rise about to be delivered - also looking for a higher rise than my OneUp 35mm.. Also have an i9 stem which I've found to offer one of the greater rises.

Eventually with even shorter cranks, even bigger bars than Dak we will resemble monowheels with our supreme upright posture. 

The stack increase is an interesting development, it's not a reaction to the extreme reaches some frames come nowadays, it's restoring a normal body position with the benefits of a long wheelbase.

If you're looking to optimise, the Funn Equalizer is ±10 mm and also has only a 34 mm stack.  In total you can gain about 10 mm of bar height compared to the i9.

That's the stem I settled on (came from an I9). 

Sorry, back to rumors; anyone seen the Conti soft in trail casing available to buy anywhere?

New Motion Instruments gizmos: https://motioninstruments.com/products/system-2

Cheaper than before but also has some limitations (e.g. won't work w/ EXT forks, which probably means it won't work w/ Manitou either).

I have this: DMR Defy. 27mm stack. I gained 20mm of bar height!
