I was thinking about it for the DH bike to let the rear end be a little bit more efficient.
Also, why don't we see floating brakes anymore?

Anyone use an Ochain thingy?

I had one on my last enduro bike, and just sold it because I didn't feel like I needed it for the new bike. Blister has a pretty good, in-depth review of it also (came out after I got mine). I think they're really nice for bikes with certain kinematic traits, but not necessary for others. The bike I had it on had a lot of pedal kickback and high anti-rise throughout the travel. My newer bike has both those traits drop off pretty dramatically starting around 50% travel. The OChain felt like it helped reduce foot fatigue on fast, medium hits (like brake bumps), and correspondingly was able to add a bit more damping.
That said, I much prefer the feel of my newer bike with more balanced kinematics to the old bike's firmer kinematic coupled with OChain trying to take the edge off.

Wish we did still see floating brakes
Instead of pretending like antirise is a good thing
Just read it. Overall, they were "meh" about it, unless you were riding in fast choppy terrain.
My anti-rise starts at about 120% but the big majority of the time it's between 100% and 80%.
I'm envious of your need for a DH bike, let alone that over priced Ochain stuff.
Just saying.
yeah god knows getting on the brakes hard has nothing to do with leaning back
I'm saying that it's silly that they push anti rise as pulling the rear of the bike down "to maintain geometry"
What so 8lbs of wheel, swing arm, brake, casette$shifter are supposed to counteract forward weight transfer of a 140-200+lb rider and the other 20 something lbs of bike?
Nah come on.....
High antrise will just pack the rear end on braking bumps,
Race car vehicle dynamics talks about a condition where the wheel has traction then rises, loosing traction, begins skidding as it's unloaded, then as traction and antirise forces are lost, the wheel lowers regains traction, in a cycle. Seems more like a pavement thing that you might get on a road race or autocross car with an SRA with 3 or 4 link and high antisquat.
I haven't necessarily experienced this on a bike but on a motorcycle In some conditions at medium to low speed i can make the bike do it.
So why do you think floating brakes have disappeared?
Reduction in faff?
Some of the dh teams were messing with them last year
Option on a acrofive p train $$$$
The dynamics between a DH bike and race car have to follow the same rules but a long vehicle with a low center of gravity on mostly flat ground with extremely high levels of traction is going to have to deal with much higher contributions of rear braking forces than a relatively short DH bike with a high center of gravity on steep grades and low traction. Not to mention a DH bike carries the majority of mass in a large wad of meat that is actively moving around just as much as the suspension itself.
THIS
Despite tens of thousands of miles experience on Shimano E bike motors with a freewheeling* crank spider I'd still rather have neither an O-chain or WRP
But if I had to have one, fuck elastomers!
* the greatest improvement is chain retention rather than foot stability or suspension performance from percieved reduction in pedal kickback
This. I went from a bike with >100% AR throughout travel to a pair of bikes with ~60% and the difference is huge on brake bumps. And the new bikes brake way better too because you can just drop your heels and the rear tire sinks in, rather than skipping around.
It's not the mass and has nothing to do with the mass of the swingarm. It's literally packing up the suspension and affecting geometry, like I said. A particular affect on geometry that happens to benefit hard, straight line braking.
Show me a race car or even motorcycle you can lean over the back of, at 5 times the weight of the vehicle.
Every dumb idea in mountainbiking's history has come from people trying to treat them like vehicles that are massively heavier than the rider, when the exact opposite scenario is reality.
There's no other suspended vehicle out there that is a small fraction of the very mobile riders weight

I think I like to have at least a little squat, on the bikes I've been on that were closer to "fully active", old school HLs, but not stinkbug LTSs, the forward weight shift on steeps was not a good thing. You're going to get it on the fork and it's going to unload the rear, but at least with some squat and braking the rear it doesn't go into ejection mode.
Years ago I think it was the German Touring Car series implemented a minimum weight limit to reduce costs. So some teams decided to spend more money and made the car as light as possible then added weight that could be shifted around for better corning and braking performance.
just like muh fat ass on a mountainbike!
thats pretty damn cool
thats pretty damn cool
WTF? You never played Gran Turismo?
That's been a thing for like.. forever
I mean brake floaters were used on and off on motorcycle just slightly longer than mtbs.
Disappeared from both, slight re-emergence on mtb
I got an Ochain on sale for my 2017 Horst link aurum. That Norco isnt perfect and needs it. Kickback is high and i ride flats. Broke a chain at the bike park and loved how much better it rode so hunted one down.
Just had a look at those, they are some money too.
I’d love to try one on my 2019 Sender. Busted my chain at the top of a run once and loved how it rode without the chain. Have you mounted yours up yet? Curious as to how it rides. I was surprised as to how many riders are using them on the DH circuit in Ed Masters DH bike weigh in video.
Because they aren't aesthetically pleasing to the majority?
I said vehicle, not clown prop
grabbing your crotch and bouncing up and down isn't a traveling with a vehicle

have you seen the sunglasses most mountainbikers wear these days?
the real reason is that the supposed massive superiority of floating brakes rely on two assumptions that sort of apply on dirtbikes, and apply much less with mountainbikes
and there was one frame in particular that floating brakes made worse.....because it turned the bike into a bucking catapault when you hit the brake hard

Rappers do it and call it music and entertainment and talent they make millions. So find a way to race em..
Very true...
I mean the "maintaining geometry" logic in itself is sound. If your rear is completely unaffected by breaking forces those forces don't magically dissapear. What's up for discussion is how much you can control front dive and geometry change under breaking by changing anti rise. I didn't see anyone going specific and talking if the difference is noticeable or just theoretical. Then again I might have missed something and maybe Steve for Vorsprung talked about it.
I have one on a DH bike and it makes the suspension feel a lot smoother. It makes a big difference, imo.
Similar to a low POE hub or different?
but "pedal kickback doesnt exist something something derailuer takes it up" - one of the regulars
is the biggest difference mowing down braking bumps?
I use it with a low POE DT 240 hub. It has elastomers and it’s set to 12 degrees. There is a lot of room before it could engage. It makes a pretty big difference for bump absorption and suspension improvements.
It makes everything feel smoother and your shock feels way more dialed in. I’d say it’s an improvement everywhere and the higher your AS then the better it will feel.
