Not necessarily directed at you Dave but just tacking onto the conversation, that along with bushing sizing the other important part is lowers alignment.
Because lowers are cast they're not that straight when you get them, and through mistreatment can bend quite a bit. But more importantly the uppers aren't perfectly true either, so with most forks they need a bit of bending to align the lowers to mate with the uppers.
The factory gets them to a standard and just combines two, but if you get a slightly left point lowers and right pointing uppers the fit is quite bad.
I'm changing out my ZEB CSU because it creaks like my knees in the morning and I'm hoping everything still lines up nicely. I'm guessing the best thing to do is check how the CSU moves in the lowers before swapping over any internals. Lowers were burnished with a .07 die.
Yes, and make sure you have a hub spacer in the lower leg when checking
I burnish bushings in my struts so I'm interested in this topic, but we're really getting in the weeds here.
Let's continue this discussion here: vitalmtb.com/forums/hub/fork-friction-burnishing-chassis-alignment-etc
Did the old brightness trick on the EXT pic from their instagram. Cant tell much from the pic, but there are some differences compared to the V4.
Cant spot it from this angle, but if its a cheaper version as someone earlier commented, we can suspect that it doesnt come with an HBO, or at least not an adjustable one as the V4. Adjustors/lockout look similar otherwise. Possibly a normal/heavy spring instead of their lighter springs. And it looks to be a "regular" chrome(?) shaft, instead of the V4's DLC coated shaft.
Might be some other differences, but it will be interesting to see how much of a difference it does to the price.
I don’t see anything on this new orbea bike that’s worth the hype they’ve been building. Specifically i heard on (downtime I believe?) that it supposedly has some new features that aren’t seen elsewhere. Surely the weight compartment can’t be it? Is anyone noticing something that I’m not?
Yeah, 0.1mm is as large a burnishing head as I've ever made. That is the max limit for me for sure.
In the last decade Nike, Adidas, etc. made factories which focused on robot automation instead of relying on people in China to make shoes. Long story short it was not profitable.
Point is, could you make a robot to burnish bushings with enough time and resources? Probably. Is it cost effective? Very unlikely.
The heads I've made have a bunch more lead-in than the almost square heads that people sell. More lead in makes more sense to me.
140mm in the rear.
+5mm
Is this you?
😉
you at least could call me a dumbass, else it doesn't work
Not sure if i has already been discusses, but Pirrion seems to run a non production Supreme.
Current supreme has the Brake and axle on the SS this one has it on the CS.
Not sure how this will affect kinematics
very rought astimation on what this would do to the Kinematics of the bike:
Blue is the version pirrion is running, pink the production
is high antirise the new trend?

a lot of stuff for the new Rallon on the Orbea site
New propain tyee just launched about an hour ago.
Interesting to see both Ochain and Trickstuff brakes come as oem. Its this the first bike to come with Trickstuff from factory? I know there was a scott scale in limited numbers if that counts, otherwise I cant think of one.

I would guess that A ) this has something to do with Trickstuff now being owned by DT Swiss, so maybe better distribution/manufacturing potential, and B ) this shows how few 'Factory' models Propain is likely to sell
Edited because I got caught by the B + ) =
, which still crops up on faded-red articles from time to time and I find hilarious that no one seems to check or change that
Do you see a change in Anti rise?
More photos
Yeah I think that too.
We've already seen quite a few bikes now this year that doesnt come with the "full" sram or shimano package. Instead they have started speccing TRP's or Hayes as oem on some bikes. From YT and Spesh for example.
No doubt DT will try to sell these as a package deal with hubs/wheelsets to manufacturers. And if the quality stays despite moving the offices/factory, hopefully more people will get to experience great brakes.
The cover is officially off, Orbea's new Rallon DH and Enduro bike is live - https://www.vitalmtb.com/features/first-ride-revealing-rallon-orbeas-dual-purpose-enduro-and-downhill-machine
Rallon Highlights
- Carbon front & rear triangle // alloy rocker and lower link
- Enduro - mixed wheels or 29-inch // DH - mixed wheels only
- Linkage-driven single pivot design with Orbea's Concentric Boost rear axle pivot
Travel:
- DH - 200mm rear wheel travel // 200mm fork
- Enduro - 170mm rear wheel travel // 180mm fork
- Progressive and linear leverage rate adjustment
- High and low geometry flip chip (enduro models)
- 442mm or 450mm chain stay length
- +/- .75-degree head angle adjustment
- Internal frame storage and water bottle mount
- Optional weights can be added to the lower link (up to 583g DH/550g enduro)
- 148mm boost rear spacing
- Sizes: S-XL
- Enduro builds: E10 - $5,699 // E-TEAM - $7,199 // E-LTD - $9,999
- DH build: D-LTD - $8,299
- Weight (size XL, weights installed): E-LTD - 36.3 lbs (16.5 kg) // D-LTD - 37.1 lbs (16.85 kg)
This is a very elegant solution and makes perfect sense in the economics of product development.
Also the best implementation of a Neo Shock to date. Build a bike with great descending characteristics and use the shock to sort out the climbing.
The bike comes with 3 weights. I applaud the out of the box thinking!
That Rallon is specced with the unreleased XTR M9220 brakes as well.
To say it plainly, yes. That's why you've been seeing the chainstays on nearly every production DH bike settle on a midpivot. They'll all calculate the rider's CG differently, but nearly everyone is chasing high AR numbers at the moment, and the easiest way to do that is to change where the chainstay mounts. In that graph the bike reaches the 100% AR mark at around 40-50% travel, so it'll pack down a bit at sag, until it goes past that 100%, where it will want to stand up a little. This basically means the bike is experiencing a form of equilibrium under braking, any braking force at any point in the travel will try to bring it to that 100% mark.
I love this. For ages brands were saying their Enduro bikes were DH bikes you could pedal, but nobody put their money where their mouth was until recently!
