Just to share it specifically, here is my full rocker setup guide. I do recommend a counterweight for most trainers and making absolutely certain the bike & trainer are dead-center over the pivot axis.
What’s the difference between the Realplate and Realplate React, besides the price?
The React adds fore/aft movement.
Remembering the sea sick feeling I had on the Kickr Bike, I feel I need more lean.
Anyone using it with a Tacx Neo Bike? It would seem to need a wider front end to accommodate the front legs. Thanks…
I have a Rockr Axis for the Neo Bike–it has a plate that you add that accommodates the back legs–no issue with the front legs. ROCKR AXIS
I’ve got a TurboRocks (without fore/aft motion) with a Kickr v5 also. My apologies if this is obvious, but don’t try and level it to the small spirit level that comes attached to the back of the Realplate - the Kickr is heavily weighted to the flywheel side, so you’ll be immediately off balance. Get a separate spirit level, set it on your saddle, and inflate the balls to level that instead.
Thank you very much. I did exactly that 
I levelled it to the small spirit level on the back. I’ll get a spirit level and set it on the saddle.
I may swap back to the 2T, which would fit on a rocker plate easier. 
What can throw you off is something caked hysteresis - where the rocket doesn’t always return to the same tilt each time even if you haven’t changed any weights / positions of the weights. There’s indecently some friction and play in the system.
So when you go to level things do this:
- check the level as is
- purposely tilt the rocker to the right then let go, check the level again when it stops moving
- purposely tilt the rocker to the left then let go, check the level again when it stops moving
- You’ll probably have different results each time, so take the “average” of your level readings. Then adjust and go back to 1.
When you get the balance good your average will be level. Since your body is constantly rocking back and forth a like bit, it’s all good.
That said, if your pedal stroke is choppy or you rock on the saddle a lot, you’re going to find the rocket moving a lot. And if you sit on the bike crooked or your hoods aren’t even, you’re likely to tilt to one side since your weigh a lot more than your bike and trainer.
I think I’ve got it tweaked now and after just one ride, I have to say this is life-changing. I was feeling slightly worried about spending that much on a rocker plate, but it was worth every penny. No more saddle sores, and I can already tell I’ll be cycling a lot more thanks to this. You really can’t put a price on that.
Also, I just wanted to thank everyone who shared tips and advice. It made a huge difference and helped me get things sorted.
RIGHT ON!!! Always great to read these experiences 
Thanks for sharing and dealing with the necessary teething pains of setup. But as you see, there is really something behind adding motion to previously rigid setups, as those aren’t really anything like riding outside. Happy rocking from here on out!
Saw this posted on another forum - seems like a really smart idea:
Better than rigid and simple, but not my preference for a ‘simple’ rocker with the unsupported center. This will pitch and bounce in ways less desired than more rigid center pivots.
And the MP1 is apparently discontinued too…
Yep. MP1 is “no longer available.” I got mine on sale for 1/2 price 3 years ago. Saris got acquired ~3 years ago. Their trainers are all on sale at prices that I think would be unsustainable.
I understand their (likely) original goal, but the pricing on the MP1 was laughable on introduction. Simply unwarranted for a new product category that was understandably questioned at the time. Unfortunate that they essentially started with a halo level product when we say success with far more simple designs at the time. It acted as an impediment for those unaware of the much more fairly priced options.
I remember thinking that if they are all that high priced, a rocker plate was not in my future. Like the plastic parts from Tacx for the 2T. $300 for plastic parts that have such a limited range of motion? Ridiculous!! They offered them free at one point, with a purchase. Thought that I’d call them and say ‘Well, yeah, I bought one. Send me the plastic bits!’, but it was ‘new’ purchases (of course). But I know there are far more reasonably priced options out there. I was just surprised that they would kill something that was obviously rather overpriced when it seemed they needed the money. 
Picking this up from a very old comment. I am now considering adding an Elite Rizer to my setup. I currently have a Tacx Neo 2T and a “half” rockerplate that supports the trainer itself, not the front wheel.
I was wondering if anybody has any experience with a rear-wheel-rockerplated trainer with a “static” Elite Rizer for the front wheel?
I can see on youtube videos, the mount on the Elite Rizer allows some left-right and fore-aft movement, but with the rocker plate there would be additional twisting forces on the mount and of course also on the fork.
I have an aluminum frame from an ancient bike, so wouldn’t be a problem if it broke. I am curious regarding the mount on the Elite Rizer though. I am sure climbing or sprinting exerts quite some force on the mount…
Any views appreciated!
Has anyone used the E-Flex / E-Flex Plus on a different trainer than the ordered version? I have an Elite Suito. InsideRide doesn’t list the Elite trainers as compatible, but i’m thinking about gambling on getting an E-Flex Plus for Kickr Core or another model and trying to make it work as best as possible.
Can’t speak to the specific question, but I ride the eflex plus and love it. The kickr v6 is nearly half off right now and worth it for the e flex plus if you can justify it.
The installation is very specific and the bracket is customized to the Kickr. As you can see, the Kickr has round legs.
Also, the e-flex has a leaf spring which is designed to counter weight of the Kickr flywheel. And it rests on the rear of the Kickr foot.
I’d just get a Kickr and an Eflex and sell the Elite. I love my Eflex. I’ll never indoor ride without one. Also, if one is getting an e-flex, a Kickr Core is probably the way to go since you no longer need adjustable legs. Although, one benefit to the Kickr is that with the e-flex you use the 24” wheel setting to make the bike lower to the ground. A Core with an eflex will sit a little higher because it doesn’t have a 24” wheel setting but I’m guessing that it’s a minor benefit.
Thanks for the multiple replies and pictures! I think i missed the boat on the kickr sale, but I am considering selling the Elite and buying the Core.
