another taipei show video. very little MTB content, but interesting look into how things work. he discusses transmission and frame tolerances a bit.
I found this in the instructions
The issue is people think tine and time again that pedal kickback is the only thing this helps with (and it does help with that every time your rear wheels is locked up or close to it, the actual speed doesn't matter then), but it also helps with chain slapping around, the free chain weight isn't that little considering how fast it oscillates in those slomo vids. It absolutely is heavy enough to transmit vibrations through the chainring to the cranks.
and shane miller's taipei day 2 vid - first 7 mins is mostly talking. show footage starts after
But with the Ochain the chain can move/slap around even more.
Thinking about it the only way I can see it helping (I've ruled out a few other theories) is that when the rear suspension goes into compression, the cranks won't be tugged on as the chainring can rotate freely - if the increase in chainstay length requiring the derailleur cage to move wants to be compensated by the top and lower length of the chain, the Ochain allows that. Running a solid chainring requires the length compensation to occur on the lower length of the chain only and invariably rotates the cassette. The cassette can maybe stay put somewhat running an Ochain.
If that is the case, enduro and the large cassettes should see even more of an improvement than DH bikes...
It can slap even more, but you won't feel it as much through the pedals 😉 and we all know racers care more about feel than anything else. And to be honest, who doesn't?
especially on flat pedals it calms the bike down on yank
Is it April elready?
The front end and headtube on this bike look just like the front end of the TEMPO, which we know has headset routed cabling. Plus, as the other person said, no port on the headtube/downtube area. This is surely going thru the headset.
Intentionally punny typo?
Now this is interesting. What do we make of this? They just rolled out the (super underwhelming) Stealth lineup, so these are what? Either a year plus out from release, or they're slotting in a DH-oriented brake more powerful than Codes.
Also, anyone know anything about the dropper situation? I thought we'd see a Reverb AXS update, or at least introduction of a 200mm (I've heard it's showing up on dealer B2B sites) this week. I guess since that's a RockShox product and the launch this week was SRAM focused, it makes sense not to have included it. But folks are saying April for RS launch of Boxxer and Vivid, and it seems like a dropper update doesn't fit that well with a DH-oriented launch. Curious...
Oh Ellsworth....
Don't ever change.
kill me please
Speaking as someone who works in product design.
The headset routing thing is still happening because these designs are done years out. So the early adopters stir up public sentiment first. So when it gets released and the public is saying "get fucked" the companies that are later in adopting it already have those designs locked in during product cycles. So they can't do anything for a year or two because all the manufacturing orders have already been made. Then you have another 2-5 years of having to sit on that design because of tooling amortization. So we're in the middle of the companies really not being able to pivot even if they want to.
Also this can be blamed on roadies just like all the garbo press in BB shenanigans
Is this the new AXS dropper?
Edit: He said it's just reversed in the comments fwiw...
Meh, got sniped...
Looks a bit long and bulkier than a normal axs reverb in my opinion. Kinda like the battery clips in from the bottom up?
He posted in the comments that is reversed in order to avoid tyre buzz.
Derailleur looks HUGE on a regular size mtb
Nice video by Steve from Vorsprung about chain slap and pedal kickback > https://www.youtube.com/watch?v=grNUgu0H9YA&ab_channel=VorsprungSuspens…;. I totally see why the O'chain would help with the chain tugging on the pedal when bouncing around. I think it would also help in some slow speed scenarios like the bottom part of Leogang's WC track.
Something from Spesh popping up tomorrow:

Not intentional, haha…
Looks like the sensible way round. Battery + tyre + mud isn't my favourite.
When you want to simultaneously up vote because humor, and down vote because ridiculousness.
No headset cable routing tho…
That was 100 times more clickbaity than anything Abus Helmets ever did.
Looks like Sour just leaked new Ohlins.
Funny timing as I was looking into a bunch of Ohlins stuff just last night and went down a rabbit hole.
My speculation is that this is the new shock Bruni has been hiding under the cover the last couple years. It's a change to a spool valve like their new moto Flow shock and they happen to have released an electronically controlled spool valve on a Yamaha moto in the last year.
I'm just a guy, but how can you tell there's a spool valve inside a shock from a drawing of the outside of said shock? All I could tell is it uses a coil spring and has knobs on it.
He's guessing its a spool valve from the handlebar remote Loic has. A spool valve makes sense functionally as it literally just diverts the oil flow to a different outlet.
The reason why I don't think there is a spool valve in there, is because how do they fit an entirerly different compression damping setup in that shock to divert the oil flow to. That shock is the same size as a normal one, there simply isn't enough room to cram it all in.
A way to think of it is like the Push 11-6, a spool valve run by a servo would switch the compression setup just like how manually you flick the switch to swap between the two setups. Im sure Darren could answer it, but I don't know if Push use a spool or a gate for that setup
Also I can't spot a difference between that CAD drawing and the normal TTX22.m2 Trunnion. Anyone else spot a difference?
Seems i have looked at the side load version too many times and forgot that they use this layout for the trunion mount. Doh.
My speculation for spool valve comes from their newer mx TTX Flow shock.
Seems I can't post links. Google Ohlins TTX Flow to see their moto shock.
The electric control from this Yamaha moto shock.
Google Ohlins Yamaha M10 Sp
Combine those two and this is what i speculate the button on Bruni's handlebar is controlling.
FYI, Multimatic has a patent on spool valves that covers use in all vehicles, if I remember correctly even bikes. If Ohlins is using it here, they had to pay up.
A spool valve isn't much different to any other valve used in dampers when it comes to electronic control, anything can be locked out with an actuator, it's just a matter of finding the best kind of actuator and location. You can even have a solenoid poke into a channel to block it off and you're done. Supporting the spool valve with an actuator is actually a bad way of doing it as the forces required to hold it in place could be very high requiring a strong actuator.
