 Sharpie, the worst tool for keeping MTB secrets. Looks like the new caliper is MAVAN or NAVAN.

 Here's hoping the 38mm Boxxer does actually have the same Zeb casting and bolt pattern for the fenders, the front lip on that fender looks just right. Current Zeb fender is a bit weak.

Didn't even look closely enough at my own post to see that, good eye.

I actually just solved the floppiness of my own Zeb's fender the other day. Realised it rattled in the rough, and that there isn't enough bracing outside the plane of the 3 bolts, they must've realised the same.

+1 for rattley Zeb fender. tried to add some foam to quiet it down but didn't help. Adding additional bolts might help, but would need a new casting.

No it wont, they got fox to follow. Added support using the air bleeders

...unfortunately I have broken numerous Mudguards from Fox due to riding in the cold, or by loading the bike in the car. The support at the air bleeders is the weak spot IMO. Beginning of the year switched to RRP and have been happy and rattle free since.

Now back to team rumors...

Well, solved might be a stretch because I didn't ride it yet, but put some mastic tape on the two 45 degree surfaces seems to resist my slaps well enough.

J bend confirmed, 32 spokes if I see correctly? 

So 240 exp hubs, competition spokes and fr541 rims? 

Hm... 🤔

If there is the opposite of Sharpie, this is it.

Some interesting stuff hanging off AP’s Commencal V5. Top of the left fork tube and rear axle / caliper.

Could be. You can see the data logger on the riders right fork leg.

Ive just never seen anything like that mounted to the top left of the fork with a round tube. Or on the gear brake caliper. The BYB data system is mounted on the downtube.

Do you think they are simple tube "counter weights"? Would certainly take a few runs to get used to the technology.

 

Why are quotes generated around counter weights?  Do I now need to go to the other, other-site to obtain cavalier use of AI?

Formula is teasing new product launch on Friday. Is this the elusive Selva XL dual crown enduro fork? If so, I am tempted - very tempted.

Oh… I certainly hope so. Dual crowns just make an awful lot of sense for >160mm forks.

speaking of product that's yet to materialize on sale for the public..... anybody know what's going on with the box stealth hubs?

Read in the pinkbike comments that the new SRAM Maven brakes will be mineral oil. Interesting

Doubt it. The block is unsprung on the rear but sprung on the front. It would also have to be a tuned mass damper to achieve this functionality and I think a tuned mass damper might be quite heavy to do anything, depending on the frequencies that were intended to be filtered out.

To be completely honest, not thinking it through completely, I don't see much of a use for an interter-type unit on a mountainbike, except for pedalling performance. In F1 (and prototypes) Inerters were used to take off the spikes in forces in suspension to ensure as constant force as possible on the tyre patch as that gave the most grip. And I think one of the effects was it made the car seem much heavier to the suspension than it actually was, effectively improving the sprung/unsprung ratio.

For what it's worth, they were banned in the new 2022 set of rules: https://www.formula1.com/en/latest/article.tech-tuesday-how-2022s-suspe…

Considering it's being run on existing levers, kinda doubt this one. But if true, I guess it's time to stock up on current (old?) Codes Smile

Code levers could probably run mineral oil just fine. Worst case they'd have to change material of some of the rubber parts. So they could be mineral and look the same.

The only issue would be the rubber- EPDM for DOT fluid, buna for mineral oil.

But the reservoir membrane would require a new tool for it. That's why I find it kinda unlikely. It's not a problem as long as we're talking about O-rings, but when custom seals come into play it becomes a bit different. Not impossible, a new tool (to cover different molding characteristics of a different material) is a few grand at most and most prototypes cost more than that, but still...

I guess we'll find out sooner than later.

They could be using the same internal soft parts as the DB8. The outer body is similar to the Code.
