Using bladders for water only is a big difference to putting isotonic drinks in it... If you put anything other than water in it hygiene and upkeep of the bladder is very very important 

Wait so those mushrooms that grow in my pack are not healthy like that blueberry flavored bread i have in a cupboard after three weeks?

DESCRIBE THE THING!!! My brother in christ you are posting spy shots of some byb telemetry device that nobody knows about. Stop being cryptic, nobody here likes that. Tell us what you know about it if you're allowed.

Looks like a TMD is hanging out on the steerer tube. And, is that another sensor zip tied to the rear shock?

Probably the position sensor or whatever the device is called that measures the stroke?

Just don't use sugary formulas there, it'll last much longer.

I'll never forget grabbing a older bladder I thought I'd tossed that I'd filled with a Redbull/vodka/OJ Mix I used at a music festival for three days straight in the hot sun and then it likely sat for 9 months with water, in it after trying to clean it out, having likely thrown out the fresh one I'd picked up to replace it by accident after using it once. The first swing tasted weird and the second one I puked and went home. 

Take care of your water containers

Motorcycle endurance road racing started using this in the early 2000s.

This came through my inbox this morning, and I figured at least a few water pack yielding individuals would find it interesting/practical. The Ai voice is also too much 😂 Kickstarter HERE 

Fucking finally! Amirite? 

I'm curious how it'd work to filter out the stale taste of that one beer I regretfully poured in my pack 3 years ago

Re: Water satchel sanitary issues/remedies. One of the best bladder & bottle tips I ever got was from Dirt Rag (RIP) ages ago. That tip? Denture cleaning tablets. 2-3 depending on the size of bottle/bladder. Works a treat and even adds a slight minty taste to the water, which is better than the plasticy/rubbery taste of some of the aforementioned, IMO at least.

Anything to prevent creaking is a big hell yeah from me. I've beat this poor horse to death, but single crown forks shouldn't be a disposable item for the bigger and/or smashier set.

It seems like a thread-on crown race that in turn squeezes a flanged steer tube around the upper crown could fully prevent creaking when combined with this one-piece upper.  

Shoots, you might even be able to use a 1 1/8 without creaking with this design, allowing a massive amount of headset adjustment options. I wrote it here, can't be patented, let's make a standard, lol. 

Keeping the racenut from unthreading is likely the 'no it won't work' challenge. Here's a quick sketch, tell me why this idea is either stupid or workable - I'm not an egineer I just overthink everything all the time.

That would be a crazy tooling/fixturing setup to machine that from a billet if that's the case. My bet is that its cast then machined to provide the necessary tolerances and surface finish. Either way I would really like to see a video of the machining in action!

Creaking can come from any of the 3 tubes in the crown…  so ideally you’d address all of them at the same time.  I also think more parts=more problems.


The one piece is awesome but obviously not going to work for anything price sensitive.


I know RS did a ton of testing to try and fix creaking CSUs as it’s a significant warranty cost to them and also hurts image.  I believe we had warranty data showing good progress but yeah it still happens.  My Zeb is loud AF.  Haha

The steering tube is the most highly stressed component on the fork and possibly the whole bike, so adding stress risers in the form of threads is a non-starter. 

I think creaking can be nearly eliminated in the current design, but at the moment it comes down to the balance of increased production cost/time vs warranty cost/exposure for the big guys.

Intend make a press in version of what you're describing. Pressing this in is likely much easier than threading:

No photo description available.

Also I'm sure this was unintended, but I got a laugh from this, maybe you'll find it funny too:

Looks like the part is machined but it really doubt it's cast - works for lower on rsu forks, wouldn't work for the crown and steerer. And with Intend sales numbers die casting anything (to get a decent casting quality) is a no go. Better to just start off with a block of aluminium.

As for threaded crown race, no way are you putting enough axial force on that thread to make it work better than a pressed in interference fit that we have these days...

Yeah, so dual crowns I guess. Turning diameter on eebs is probably stopping that progress. Oh well, I'm getting old and can afford replacing forks on the regular. Still feels wasteful and CSUs are in need of an elegant (aka robust and affordable) solution.

Isn't the Rockshox RS-1 already a single piece (carbon) inverted fork? And those failed carbon linkage forks from a few years ago?

I think a lot of the issue is oem concern about weight and stack height. 
 

Make the crown height 2x taller and add wall thickness to crown, steerer and stanchions I’ll bet you solve the problem completely.   

Easier said than done though.  Forks would be taller and heavier for same travel.

My warranty replacement Zeb CSU crown is thicker around the steerer tube and the flat area around the crown race is now wider than the headset cup. Hopefully this makes it less prone to creaking, but making the interfaces taller would be way more effective as you say.

Yeah its definitely not cast. Im guessing they (radoxx who machines them) has a wide block of billet aluminium, and machine out several rough forks, and then put each one through the operations in a 5axis machine

The "legs" also have way rougher machining marks than the normal forks do, most likely since its one piece, they cant put the legs in a lathe, but rather has to have the cnc machine swivel around the leg to remove material. 

I believe they also use the regular steerer pressed in like the other forks.

Will be a limited edition run, orders opening in a few weeks 

They probably start off by cutting them out of a block like this:
