They are definitely running a different damper in the fork. This is from Ancillotti’s story. Looks like it could be the Nero damper (with the HSC dial taken off)?

Coil also

That crown looks identical to the one on my Selva C, the text on the axle is definitely different, the casting looks slightly different, although it's hard to tell for sure with the livery on it. The main difference looks like along the supports that run down from the arch on the inside, they extend further down on the Selva. The preload adjusters and top caps look identical, although the damper obviously lacks the lockout and compression adjuster (or CTS, I can't tell which)

Those stanchions don't look to be 38mm though, maybe 36 at best, but pictures can be deceiving. That or I'm just huffing copium because I just got the fork in for one of my bikes and really wanted a larger chassis version Smile

With high pivot getting a lot of attention lately I’m very curious about this Dave weagle system on the proto pivot. Everyone mentions the idler drag and need for a lower chain guide idler but this system seems to eliminate both downfalls. Or does this system still have similar drag? Have to wonder if this gets more attention for trail/enduro bikes where pedaling efficiency matters

Looks like RockShox quietly released the next version (A2) of the Reverb AXS.

Minor changes, lower price (but remote is not included any longer) and 170mm is still the max.

I hope they fixed the internals. Blew up my 3rd one in a year.

It has the same spec as the A1 with the exception of not including a controller and being e-bike certified. Seems more likely to be a new SKU for AXS-integrated e-bikes than an actual refresh.

It's patented by Dave... But the drag should be similar as with an ordinary idler. The benefit is the packaging as you wrap more of the chain around the chainrings so the retention should be better, the chainline at the top and the bottom is closer to what low pivot bikes have, thus chain length is not extreme, chain growth is more along the lines of what is known, etc.

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.

(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.

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.
