I'm pretty sure he had a short cage axs setup years ago in some edit. Not long after axs came out. It probably doesn't mean a dh axs is incoming. 

Im talking about the dropper post. You are right he was running a 7-speed axs a few years back though

Oops, I'm an idiot. Weird to have a dropper on a dh sled. Maybe some of his shuttle trails have flatish bits in them? Or maybe it's just a marketing thing for sram.

Its funny you mention that, as that custom kit Nigel (NSR) made was the one I was specifically refering to, and the team got told they are not allowed to do that, and were forced to change. 

But yes, this will be my last post on this subject.

Again, go have some beers with mechanics, youll learn a lot.

Funnily enough, that said rider just won world champs on the tuned fork, must feel great when you find what works for you at that level and they tell you to go back to stuff that is a lot worse. But I know that's just how it goes when you are paid to run XYZ. Which begs the question, how on gods great earth can so many racers run different tire brands and don't face the same results? It must be in the contract right?

Just got back from 2 weeks in the French Alps - I've got an Ohlin's TTX2Air, SD Coil that came on my Wreckoning and a Fast Fenix Evo - bloody amazing shock. So controlled but still poppy - was considering selling my Wreckoning for more of a plow bike, but no need with the Fenix.. Really good kit.

I think the Demo Proto is a four bar with the pull link to drive the shock, so you get that sexy S shaped leverage curve and they can still get their axle path and anti rise they like.

I'm not sure why theyve kept it hidden for so long, does it really matter that much? Or is it because of the shock their running that they had a cover on even before the current proto frame?

Bruni has the electronic lockout (or whatever it is?) shock. Finn doesn't have the control buttons for it on the bars (correct me if wrong), so presumably his bike doesn't have it. And his bike is still covered so they're also hiding the linkage. And yes, it's a horst wheel path with a pull link and rocker to drive the shock (if short Charles and co are correct in the layout, and I think he is). Has this layout been used on a bike before? I don't recall any. I wonder if they're aiming to patent that suspension layout? I mean, Specialized had the horst patent for years and it was a big part of their brand identity and marketing etc. Perhaps they want that kind of situation back? 

Edit: Most companies just put some stretchy fabric over it an call it good. Specialized has got hard plastic and such. And they must completely close their pit area every time a mechanic has to take the cover off to work on something. My point is that they've gone to great lengths to keep it hidden, which might track with them wanting to patent it.

Makes for damn good marketing, that's for sure.

As for patenting it, I think it could be argued it's not patentable (in the shape we assume it's in). Unless it's specifically the chainstay shape and attachement of the linkage. You could argue the currently public demo uses the same layout - a horst link with a linkage driven shock where a pull link (the vertical one) actuates the shock.

This is just not true, top riders often use revalved or non-stock dampers in both forks and shocks. It is also pretty clear from the Dialed series you mentioned. Also, there are really no A-kit forks or shocks sold on the market for DH bikes unlike for MX for example, so it will always be revalved stuff. Also, brands might not want people knowing their riders are not on stock suspensions, but there were people running custom coil sprung boxxers or modified shock bodies in the past (check the NSR website) so..

Anyway, this is off topic.

I gotta be honest, thats a pretty funny thing to say....Go have beers with some WC mechanics to get all the goods. 

1. My family has been involved with automotive racing for as long as I can remember, having a "beer" with them would get you nothing but a load of nonsense. 

2. I dont trust a single thing from racers (who are generally clueless about setup, etc,) or team owners, PR people, mechanics.  Theyre all lying to you, about everything.  No one worth their salt is out there giving away trade secrets over beers with someone they dont know.  Anything you see in the pits, has been placed for you to see, to drum up hype.

3. Why would I, as a team mechanic, give anyone info that might jeopardize any little advantage my team might have?  What are the chances they are trying to sell you a bridge, I know damn well I would, every chance I got.  I certainly wouldnt be out there putting my job at risk for a couple beers......

4.  You and I can easily go and get ourselves a tuned damper, there are a number of suspension companies that can do it.  Along with rental telemetry to test and verify.  If youre a team manager, and youre not trying to use everything youve got to your advantage, well, you might be doing your team a disservice.

Apologies if this was posted previously, but is Push working on an air shock (or just messing w/ us)?

Yeah, I'm not sure it's patentable, it might be unique enough, not sure? The patent system can be are a minefield of clusterfucks sometimes, in the US anyhow. I'm just speculating as to why they've gone to such lengths to keep it under wraps.

I'm shocked Flight Attendant didn't originate on the SID and SIDLuxe considering remote lockouts are way more common in XC.

It's less ideal, but I'd put it way down on my list of things I care about in brakes.  The main reason I sold my Codes and went to Hayes is how incredibly light and smooth the lever feel is.  I loved the ease of bleeding the Codes, availability of parts, contact point adjust, MatchMaker... but once I felt Dominion levers I had to have them.  It must be a lot due to the piston/seal friction and return spring stiffness, because Codes have a bearing mount too.

New Trek Slash could be released very soon, maybe as early as on Thursday…let’s see, but apparently in August.

Seen the SRAM brakes on few bikes at Fort William at the weekend, Ronan Dunne was using them…. Pads looked like the loaded in from the bottom.

Is that an issue? when swapping pads you should re-surface the rotor a tiny bit anyway, so you have to remove the wheel anyway?

I've never thought about it, but i'd prefer a solid brake than the option of sliding in pads from the top

Nino has been running the fork and shock (we couldn't see it) in the past two world cup races. 

8/8/2023 4:20pm

With the existing post mount standard, brakes are at a point where more line pressure and or bigger pistons and pads will necessitate things like this. Maintaining good stiffness and accessing the post bolts fight each other when combined with all that. I’m not a fan of all the random standards, especially considering they aren’t well adhered to (iscg is the worst), but wider post mounts wouldn’t be the worst thing.
