Remember a few pages back (eternity ago, probably in a previous Creation or Big Bang) someone linked to a patent that has a floating bypass for dampenening? The idea is that you get 1cm or whatever of undamped fork movement.
On my ride this morning I was thinking, isn't that what those pucks do in the latest Rock Shocks forks? EXT's fork does this on the air spring side- the bottom of the push rod has a 1 inch literal coil spring connecting it to the fork lowers. Why not do this on both sides? Create a half inch or whatever spring that has to bottom before the damping connecting rod is engaged (in reality it would have a dynamic relationship with the damping).
A few years ago some small brand did this with rear suspension too- the front mount for the rear shock was a tiny swingarm with an elastomer so that your rear suspension compressed this tiny elastomer along with your air shock.

It looks interesting but who decided it's "revolutionary"?
Edit: I didn't notice the article date! The absence of this product on any modern bikes certainly puts the (hypothetical) "revolutionary" debate to bed.

Vibration mounts lol.
If only bikes had soft flexible tyres instead of rolling on steel tracks.
I’d rather walk than ride a road bike.
Gear boxes, or at least the benefits of them, make way more sense to me than a derailleur...

Gear boxes, or at least the benefits of them, make way more sense to me than a derailleur. The disadvantages in climbing, shifting speed, weight, etc seem negligible. Aside from the grip shift, because that is an absolute no-go. Like putting a thumb throttle on a dirt bike.
The approximately 13 watt loss going to the Pinion is less than I thought it would be. Still, that about the difference from a an Exo to a DD casing, enough to be quite noticeable for a weakling like me.
What I'd genuinely like to see is no drivetrain, and an e-bike that generates juice through pedaling and electronically sends that signal to a rear hub motor in conjunction with the assistance.
As far as my bikes, I'll stick to 11 sp Sram thank you very much.

Yes it's a similar idea. The big difference is it being part of a fluid circuit instead of a spring, it's tunable and doesn't store energy. I believe one picture even showed it with an external adjustment. I'm really curious to see what Bilstein does with this.

Speaking of being curious...
I am curious if Hyundai Motors having an electric motor be able to have a functioning gearbox style of power delivery is something able to be replicated through a set of bicycle cranks. Hyundai is one of the largest companies in Merchant vessels, which some of today's newest e-bike motors share affiliation within electrified propulsion in that industry.
First have to assume there's no space to have enough motor mass be able to be leveraged against when changing 'gears'. Maybe someone from Gilligan's Island can chime in...

You’re referring to the ioniq 5 N which simulates a combustion engine and gearbox with a torque curve etc.
you certainly could do that with a bike, but it doesn’t make sense unless you want to simulate a motor bike or something. Otherwise you’d just be simulating a human legs torque curve which I don’t think would be desirable.

Fork travel: 140-160mm

A Sour Cowboy Cookie frameset weighs 3.48 kg with all it’s small parts and suspension pivots, bearings, and bolts installed. This weight is excluding powdercoat which will add between 50g and 200g depending on your color choice.
That brake looks like it’s from the same designers of the cyber truck.
I haven't actually tried the 612 brakes, I was very close but ultimately decided I there just wasn't enough info out there. I listened to some podcasts and interviews with the founder/owner of 612, I got the feeling they are basically a re-sculpted Maxima. He aimed for the same leverage, piston sizes, and mc sizes as the Maxima and ran with that on the 612s. They are obviously aesthetically very different and I'm sure they are functionally a bit different, but I gather not by much. I could be wrong.
You can select hose types/material, they use Hope pads, mineral oil based fluids, etc, all fairly standard for boutique brakes. You also don't have to deal with Trickstuff support, which I've heard mixed things on for US based customers. I don't mind the aesthetic but there just wasn't enough info on them for me to throw down the $$ to try.
These and the Beringer Br4ves are basically the only brakes still rattling around in my head as interesting potentials beyond what I've tried so far.
I don’t really plan on owning an e-bike soon. But if I did it’d be something in this category. Adventure rides in places that may not suit my pedal enduro bike and a cheap 2nd wheel set away from a fun commuter bike. I get for most people the e-bike is for smashing their normal trails in way less time (or more runs). But it’s not really what I would want one for.

I don't think a short travel eeb will keep you satisfied for long if you're already used to riding enduro bikes. Also, suspension seatposts on commuter eebs add a ton of comfort, and the storage racks on those bikes make them roughly 1,000,000x more practical for actual commuting.

First 7 speed DH setup with SRAM Transmission on the new YT Tues MK4.
Was gonna ask if that's just a GX der with a custom short pulley arm, though probably not. I'm sure it'll work just fine.
Anyone know what brake caliper that is in the background? Looks pretty awesome, like cybertruck design vibes except not super douchey

German based Sour Bicycles entered the full squish market with two models at once:
MTB – Sour Bicycles
That is the bike from Timo Pries and he builds a lot of cool stuff by himself he even has a Shock bleeding maschine build into his van.
so i think he has build the GX Transmission by himself.

3.499,00 € incl. VAT, 2 stock colors, 180,00 € gets you a custom color (they have some really cool ones, including raw)
By the numbers:
Headtube: EC44/ZS56 tapered headtube
Bottom bracket: 73mm BSA bottom bracket
Axle: 12mm x 148mm thru axle (Syntace X-12)
Seat post: 31.6mm

tempo ebike. kind of a weird combination.
If they bump the travel 10mm, could see it going up against something like a Norco Fluid VLT.
Biggest thing is that they ditched the headset cable routing as seen on the regular Tempo.

Anyone know anything about new stumpy or enduro from Specialized? Was Loic on a new bike for the mentioned shoot after Poland?
One was seen in Peaslake yesterday. Apparently it's now due in July.
Layout is like the Levo SL but without a motor

Nicolai has you covered!
That's pretty cool I'm not gonna lie. I wonder if the XS has a short enough wheelbase to fit on a bus rack?
Nothing ground breaking here, but Ratio are now selling Transmission cages. Pretty reasonably priced at £75 (sans pulleys) or £95 with.
