Every 10 years some dipshit forgets derailleur springs exist and thinks your cranks get pulled backwards on suspension bikes*

Corratec Enduro 175 mellows out with frequency-damped suspension, plus more new road, MTB
In 2014, Corratec developed their 10Hz damper to work in concert with their InsideLink suspension platform. The idea behind it is simple – provide frictionless small bump absorption to reduce high frequency vibrations that a sealed, damped shock absorber simply can’t keep up with. Because the...

Just take your shock off and hold your pedal while cycling the suspension. Its not complicated. Chain kickback doesn't happen on any suspension design worth a damn because the derailleur unwinds.

Whelp, I am ready to buy some fancy expensive slop-inducing spider to offset the high precision engagement of my fancy expensive hub.
DA FUQQ???

damn, this plus a pack of those anti vibration stickers are sure to shave seconds from my strava pr's.
oh hey it's only 300eur; how can one not?

Why end your search in such modern times?
ACS Z-rims is where it's at for ultimate compliance
Just think how comfortable your cutties could be
just look how compliant that rim is!Why end your search in such modern times?

lock the brake and you will see pk, the derailleur is on the slack side and doesn't have anything to do with PK.
i got your compliance right here:
bolt these onto a flex stem, add rev grips, and you've got a properly plush cockpit.

If you guys want flex maybe check out that Starling Murmur. I think if you corner hard enough it turns into a Bugs Bunny noodle bike situation when the rear end flexes past your fork.
I just want to turn my Capra into an idler set-up for cheap. I know I know... ain’t gonna happen.

Reason #1 I'd never buy one.
the murmur is a rad bike. not noodly at all; great corner shredder (tho i'm no connor fearon). it's just the right kind of compliance, imo.
One of these days I will get around to installing my new in box shockster on my old Turner with bolt on brake bosses for the ultimate suspension kludge.
Let us know when you do, so we can revoke your privileges.
I'm no suspension guru but the dominance of the Commencal Supreme high pivot in WC racing tells me that the chain forces have much to do with suspension performance. That and Neko Mulally got his best WC result after dropping his chain at the top. and Aaron Gwin, remember that?
How many people have had fucked runs because of a broken chain? I don't have an answer but i'd say most of them.
I am guessing some people could have better runs on some tracks without a chain not because of suspension action but because they are no longer wasting energy pedaling. Bombing down a technical track is exhausting on every part of the body even without pedaling. I've never had bike computer on a MTB but I have gone down steep roads on a road bike and once I get above about 35 mph pedaling as hard as i can barely makes a difference. Dudes who go faster on a chainless bike are probably doing so because they are no longer wasting energy they can't afford.
Suspension bikes work better chainless because there's no energy being wasted in pulling the chain on the spring loaded derailleur. You can even tell the difference between a clutch derailleur which is even worse. Doesn't mean your ass is winning a run because of it though. That's from focus and being efficient. Like the guy with the shockster said.
No, and yes,
Without a clutch the derailuer simply adds spring force, maybe a miniscule amount in low gear, and 20% of miniscule in high gear.
Take your spring off bet you it wont hold your bike up, flip it over, wont even hold up the suspension. Maybe just maybe on a bike with HUGE chain growth and no lower guide the derailuer might keep the shock 0.002" off the stop in low gear.
Now if you use a lower chain roller the chain "unwraps" as the suspension compresses and feeds the chain growth keeping the derailuer from getting tugged as much
Now a clutch derailuer,
Now those little buggers ceartainly add some stiction to suspension, best you can do is back down the clutch adjustment to the minimum needed to keep the chain in check and use a guide with a lower roller as high as possible
Exclusively yes.
Um ok ill take your (single) word for it
Man you should go back your preload off 1/73rd of a turn. So you dont feel the extra 0.2lbs/in your derailuer is adding to your super exact wheel rate that you came too without a chain.
How do you know the force on my chain if I didn't tell you what derailleur, which clutch, how old and worn, and how long the cage arm is, nor what bike which is going to vary the growth and leverage?
Instead of me messing with preload, why don't you go take a few chainless runs?
That stance is far from singular.
Like vrock said, pedal kickback is only a thing when you tension the chain and try to pedal. Just coasting along, you're standing on the pedals, it's not like your cranks are constantly trying to throw you off. All that force going through the chain wraps around the cogs and gets taken up in the chain growth by your derailleur. That crank doohicky that started this thread is just redundantly adding to what your derailleur is already doing.
Personally I only leave my chain on so people can tell how much money I spend on loud hubs.

Minus some very small inefficiency, any energy taken out by the derailleur spring gets put back in by the derailleur spring. Got any more mythology?
Chain wrap around a cassette doesn't really work that way. Unless you're putting derailleurs on full suspension fixies.
Which I wouldn't put past you.
You ever bounce the back wheel of a suspension bike on the floor of your garage and see the cranks get pulled backwards? Ever notice that's not what happens when coasting downhill with you on it?
I'm not saying what's being taken up by the derailleur is huge, but it's not nothing. Some bikes more pronounced than others obviously. And since it relies on the singular rotation direction of a freewheel hub, it's not exactly 1:1. And clutch derailleurs only provide significant friction in one direction.
