What do you mean, refined? It’s the exact same thing as it was before.  All they did was just choose two different colors. 

I think the only difference is that the head angle got steeped by just one degree

STFU guides. They actually work. They also help with the mythical pedal kickback.

External cables with proper guides/clamps.

Lastly a silent rear hub.

But none of it really matters when you ride solo with earbuds in 90% of the time. 

My issue with my Rocky Mountain Altitude is actually that the Sram eagle axs rear deraillieur b-screw will violently slap against the hanger and make really loud clanking sounds. I've taken slow motion videos to confirm this - chain never makes contact with the frame. Has anyone solved this? 

In terms of rumors and speculation, I imagine that bike manufacturers could make a silent bike but the effort involved wouldn't translate to increased sales.

It’s probably just because it comes to the boxer, which is a different height than a 40. They also could have changed the spec to look better to consumers without changing the actual geo (lot of brands do this lol)  everything else looks the same but head tube angle   Or the person entering the data on the website coulda messed up lol  


   Speaking of rumors and tr-11 I saw a recently sponsored kiwi rider bouncing around on a “new” one.   Dig around and there’s some pics of it some pages back.

look up the hall lock mod. seems like a well-kept secret. havent done it yet but it seems to be the answer for a lot of us.

Yep, solved if I'm understanding you correctly. Hall-lock mod so the b-pivot can't rotate. File the X01 b-bushing down slightly, a little bit at a time (test, file, test, file) until the derailleur can't rotate at the bolt. 

If you've got a GX there's no bushing to modify, it's a crappy steel-on-aluminum design that suffers from premature wearification. The X01 b-bolt with bushing is around $30 USD and works perfectly on the GX so get that and do the mod.

Your rear wheel will be slightly harder to remove as the derailleur doesn't pivot out of the way. But it's not too hard to get it off, easier than what we used to deal with back in the early '00s.

I really, really need to make a video about this mod, it's absolutely worth doing to silence the derailleur and it makes shifting nice and crispy, particularly on played-out GX derailleurs.

Does SRAM do the hall lock mod different than shimano? Shimano you just put a washer between the B screw bumper and the derailleur so that it bottoms out when you tighten it. To get your wheel off, just loosen your derailleur. Pic of shimano for reference. Insert 1-2mm plastic washer where red line is. I didn’t remove the c clip and b screw bumper, I just cut my washer so I could open it and slide it in there.76668900306  8E50B86A-5DEE-4473-B1BF-152A61047BA2

What about just affixing a piece of plastic or something where the b-gap screw touches the hanger, so that when it smacks against it, it's damped?

Dude, Rali chain mag!! I’ll plug it if you won’t haha. I have it on two bikes and it works amazingly well

I’m more confused on why they’re running xts with centerlines

Welcome to the wild and wonderful world of the bike industry, where you get worked to death and paid next to nothing, but there are literal piles of new and lightly used parts, even parts falling out the cracks of the building. What parts are you running? Whatever's in the pile. At least until you get laid off next week.

Quite often running used parts off returned/warrantied bikes that can't be resold. I've got a lot of kit that way.

please do make that video, i miss my 1st oem GX eagle derailleur, it was silent as until it gave up, i had both xt and a new gx and they slap so much more, nothing else has changed, i'm thinking to go ViVo but damn it's an expensive piece of component, while for sure worth it i'd rather keep the cash

Haven't tried Shimano, been on SRAM lately. For SRAM I looked briefly for a washer that was the right size, but didn't fine one. Rather than spend a day looking for a washer I ordered the bushing and have been happy with the results having done it a handful of times.

What kind of washer did you use for Shimano?

I never said refined. Just saw that they were live before their timeline they said earlier. "Coming in May". Looks like small changes only. Was hoping for a bit more tbh.

So the alloy transition that we saw posted a while back with a vertical shock and dual crown must have been the new Spire then and not the TR11

Maybe I missed the news or a previous post, but those pretty red Pike and Lyrik forks we've been seeing on athlete bikes for a while are now available for retail purchase. Was that lumped in with the 70/90/Motive release or was it just a quiet trickle out into the market?

I thought people were just like me and figured that Rockshox forks always came in Red so it wasn't a new thing?

Rockshox has run a number of red forks over the years no doubt, but the current Pike and Lyrik (also the SID and Rudy too) are new releases.

The red now becomes the universal color on the Ultimate forks, replacing the silver for Pike and the forest green for Lyrik (and blue for SID) that they had previously.

You can just use a washer on SRAM as well.  Not that hard to find.  Works great on X01 mechanical or GX with an upgraded B-bolt.

Definitely was a tr-11 or dh bike.  Shock was way too long for a sprie. Also the one I saw was also definitely a dh bike as the person is a dh athlete I saw on it

They could just be transferring the Spire to a 250 i2i shock to better utilize its long travel - always thought a 65mm stroke shock isn’t enough for a 170mm bike (or even 180 as seen with a Cascade components link)… Wink

Maybe they canned it due to the financial climate and just slightly re-jigged the existing TR11 then? 

The frame looks like it uses the same hydroformed tubeset they just have a new headtube, slightly adjusted seatstay with the CS adjuster in it, and a slightly lower overall leverage ratio. 

Maybe i'm missing something, but it looks very close to the previous model

Yeah them saying its just a prototype and absolutely nothing more I dont believe. There is a reason it was on like 10 different bikes at sea otter. 

Also, having made moulds for the carbon leg-guards, rather than using an already existing diameter of carbon tube seems expensive. And some of the plastic bits looked injection moulded, not 3d-printed. So it seems like there is a lot invested for something allegedly not being planned for production.

I believe some people here in the thread said June release for this fork. Looking at how buttoned up it looks, does not seem impossible.

Every time I start thinking about a USD fork, I look at where the scratches and dings are on my fork lowers and realize they would be a problem on an USD fork. 

They do look cool though.
