    The biggest thing I alwase wonder about is how often suspension impacts are fast enough to overcome the wheel speed and cause pedal kickback. Kickback can clearly be seen when the rear wheel is not moving, and the bike is dropped. Howevwer when the rear wheel is rolling fast downhill, you would need a super fast impact for the chain to grow faster than the wheel is spinning and actually crate tension on the cranks. Something like this would probably be most noticeable in the suspension feel when the rear wheel is locked up or close to it skidding through steep tech. Having the play in the freehub is a much better solution than something like o chain because while Ochain separates the cranks from the system, you still have the inertia of the cassette, chain, and chainring, slowing down the suspension ever so slightly in these unique situations. Regardless, I think this is an excellent design. A lesser talked about problem which is also done nicely on this hub is the bearing bracing. Many hubs (most noably i9) have the driveside bearing very inwered into the hub causing extreme stress and unwanted flex / deflection and premature alxle/ bearing wear. This hub has a load bearing on the freehub outside of the ratcheting mechanism as close to the cassette as possible, and the frehub body is directly reinforced with its bearing under that one, creating one of the widest bracing angles. this creates a more consistent hub feel and allows you to tune wheel flex more symmetrically with spokes and rim design. It's not unique to this hub, but definitely one of the best designs.

      Axle flex is designed into the I9 Hydra, that's how it gets such instant engagement. You're not wrong about premature bearing wear though!

      @@maxwellduff4958 I fail to understand your logic. You claim that this hub is better than ochain because ochain doesn't solve rear end components' inertia. But this hub doesn't solve this either as you still need a cassette, chain etc. Actually it is making it worse compared to ochain as this hub is heavier than a standard hub and that extra weight is all unsprung weight whereas ochain added weight is sprung weight, positioned at the center of the bike. To me the hub solution is inferior to ochain because of this. I can see two advantages to the hub design, first it might need less maintenance if it proves to be reliable, second it has more degree of freedom than the ochain max setting so if you have a bike with very high pedalkick ochain could reach its limit.
      Now I am with you on pedalkick, theoretically you shouldn't be able to feel it however big of a PK you frame has as long as you ride fast enough to keep freewheeling. But so many people (journalists, WC riders and riders) seem to swear by it that it must be doing something right. Hopefully one day somebody comes with a proper testing setup and can show/explain what actually happens.

      If you are riding slower, the hits are slower, but the hub is slower too. So for the same hit the relative speed will probably be the same.
      If you are going 20km/h, a 29er will do about 2 rotations per second. A 60mm freewheel will have a speed 0f 0.4m/s at the circumference. To get the speed of a hit is a bit more complicated and very dependent on the type of hit, but i think it is easy to see it will be more than 0.4m/s. Plus you have to take the cog into consideration because it influences the rate at which the cassette can catch up with the freewheel.

      @@gg4760-k5n what he means with inertia from the cassette is not the unsprung weight, but the rotating inertia from the cassette. With o chain the cassette still rotates on a hit and thats causing chain tension between the cassette and the chainring, you may not feel the tension (kickback) because the cranks are "isolated" from it but the tension still affects the suspension. The sidekick hub solves this problem because the cassette won't start rotating till the 12/15/18° are used up, which results in no tension on the chain and no interference on the suspension

      @@clemenshofbauer5740 if the cassette amd chain don't affect the crank that also means there is no resistance to their movements which also means it cannot influence suspension. Chain effect relies on chain tension between the cassette and the crank. Think about it this way, if you pump you bike at very low speed, slow enough that pedalkick is a thing and it engages your normal hub. If you keep your feet on the cranks you will be able to accelerate your bike from pumping. Do the same but don't have your feet on the pedals. Now for each pump your cranks will move slightly but you won't create any speed as the chain effect is now wasted since there is no resistance at the other end of the system. Whether you cancel the tension from the wheel side or the crank side doesn't matter as long as chain tension is not created.

      Both side of this debate has merits. However it would intriguing to see quantifiable numbers in fixed test rig. This would eliminate the placebo effect, rider/brand biases, rider style etc.
      Perhaps have a setup that holds the bike frame completely rigid then attach a nm force gauge to the crank arms and while in a neutral (parallel to the ground) riding position. Then have a piston push up on the rear swing arm axle bolt at various fixed (slow med fast) speeds to measure the amount of nm transferred to the peddles at each speed.
      Also, another test could be to hold the peddles in a completely static rigid position, repeat the test and measure the amount of rotations the rear wheel would turn forward (if at all) in the various degree options the hub offers. Both tests conducted without the rear shock attached of course.
      Just a suggestion this riders would be very intrigued to see happen Vital/E-thirteen

    Back to Back testing makes a lot of sense but you actually tested 29er DT Swiss vs. 27/Mullet with Sidekick 😆. Especially when describing the difference in cornering this could be likely related to a different tire size. Hard to say if it was really the hub or tire size or maybe a combination of both. After all cool to see that different players coming in to address this topic since it is real - I never noticed it before really but when riding a high-pivot bike for some time and then going back I noticed that there is really a huge difference - especially when riding flats.

      actually you should use a mid pivot bike. Proper high pivot bike will create a lot more kickback than the 12° allowed by the ochain so it wouldn't be faire and it would be putting some gear out of its scope. Kinda like testing a XC tire on a DH rig and conclude it is garbage ... well yeah, duh ! Other than that I would agree with you, and use telemetry system to see if there is any actual improvements aside from contextual effects aka placebo.

But for that weight and price, I'd go with an Onyx, or just save some dough and get something prettier and lighter.
