so rad all the tech gizmos! (well i think so). in semi-finals today, troy, finn and loic top 3, all with electronics. separated by just .071 seconds. luca was 4th only .5 off first place. did he have flight attendant too?

Looks like he did... can clearly see it on the fork, assuming its on the shock as well.

Also, they're not running it fully automated. Looks like a Reverb AXS controller on the left which likely turns the extra compression on/off.

Colored LEDs on the fork to tell you what setting you're in.

I was watching Bruni's Gopro footage from Fort William practice, and something caught my eye. From the footage you can actually see when he switches between damping modes from the LEDs on his stem. It happens at least 3 times: 1) blue mode off the start till at least the wood section (I did not check if he switches anything in the upper section); 2) green mode in the wood section until the second turn/shark fin after the road gap; 3) back to blue mode for the new fast section; 4) red mode from the bridge before the motorway to the finish. I think this proves that it's not just a "firm mode" switch. I guess the RS flight attendant does the same thing, but automatically. I wonder how different the damping can be between the modes. 

First switch:

Just after the second switch:

Third switch:

image-20240504144135-3

what really surprises me as a mediocre at best rider is the fact that he's going with no finger on the brake at times

Anybody notice how short Reece Wilson's stem is this weekend? Looks like a 20mm stem or maybe shorter. I don't remember seeing anybody fast running a stem that short since Bulldog on the OG Mondraker/Cesar Rojo "Forward Geometry" program in 2012.

 Rulezman developed a similar type of stem, the direct mount version is 18mm IIRC. I gather it's a similar idea to the Mondraker one from back in the day (I wouldn't know for certain). His theory is on the YT channel and PB, but I gather it has something to do with a longer bike, both reach and CS length, combined with moving the steering axis further inward.

Any ideas on the blackbox shifter ?

Probably just the custom thumb paddle.

Bruni using wheel weights. Wonder what that's offsetting? It must be something quite noticeable in the rim/tyre to need that level of 'solution'.

I would think just to balance it. My rear wheel with an insert has a fair imbalance. My front feels smooth, but notice that when in a stand it will have a certain (heavy) spot that will always spin to the bottom.

PB had all the juicy photos of Bruni's bike Tongue. They were testing rotor covers. You can al so see the bike with the cover off. There is also a brace on the derailleur hanger, I am too out of the loop on transmission stuff to know if it a stock piece.

Looks like it is an electric motor that actuates the damping dials. There might also be something above the spring collar (preload adjuster?) but it's hard to see.

Look on the table to the right. The extra shock has a… not a dial but something that does not look like that. In my opinion.

I think it is that kind of silver/black actuator like the one on his bike.

Quick question,

do you "know" they arent running it fully automated, or just making an assumption.

Could they be using the controller to toggle through different modes 'open, platform, locked"?  or simply on/off with the thumb contoller, as they dont need a dropper?

Just making an assumption based on the AXS controller. If it was fully automated, I wouldn’t expect any lever or rider input.

I bet it’s on/off as you suggested.

Or it's an override. Fully automated but can bee override if wanted because the tech is in a development phase

I think that would require the pedal sensor which sits in the crank axle. Didn't see that in Troy's video but wasn't looking for it.

image-20240505145623-1 I would assume the little black sensor next to the electronic adjuster is a GPS receiver. So there can be some amount of automation to the dampening settings based on a preloaded track map. I would guess the handlebar buttons are for override or some kind of modification if needed.

Just to add, the box that's mounted to frame is a BYB controller.  In the Data Acquisition thread, Enrico said they have a new controller with custom inputs, 3, 5 or 9 depending on the size and how much data you want to record, smaller battery than the larger original box we are used to seeing.

GPS is likely for the telemetry system that’s mounted in that pic.

I would imagine bouncing telemetry data through gps would be slow and unreliable.

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

I did not see photos of them racing the bonded bike this weekend. Pretty sure they were all on the welded frames.

May not be on the bonded frames for a bit. Neko said he wanted to test the new frames himself. I believe this is to relieve his riders of  the stress of whether or not new types of frames will make it through a race weekend.

At what point does the cover on Loics bike violate the rule about fairings on bicycles? 
it’s quite a thought out aero design, I’m surprised nobody has challenged this
