Moving the pre-cut holes to closer to the edges is the only change I would make. Being closer to the edge “feels” like the correct position, as it would give you the most out-of-the-box control over stiffness / damping.
I have a turbo rocks side to side only model and I’m very happy with it - makes a big difference on longer sessions. I bought it a few months before they released the fore-aft model, and if I’m honest had that been available at the time I’d probably have bought it. But I’m content with what I have and see no reason to upgrade - so I guess it comes down to how much the extra cost means to you.
I’ve recommended them to a few friends in the UK, all happy too - great customer service.
Was about to buy the Realplate React from TurboRocks but then thought twice about additional sound / vibration / scratching sound. Would love the additional motion but I guess this video shows the real world sound:
And I think that might be too annoying for the neighbors in the flats below me or next to me…(once was told they heard some noise/vibration 2 flats below me).
Currently have a Neo and have a sound isolation plate (with sand) under my setup to keep sound/vibration as silent as possible (seems to be ok now).
Anybody thoughts/experiences? @mcneese.chad

For sure, the typical fore-aft motion from these setups adds some noise. Most use a linear bearing with recirculating ball bearings. Each and every one of those rolling in the track, and on the linear shaft add a bit of noise. There are other reasons I’m not a fan of that particular bearing setup, but we seem them as the most common in use with this rocker design.
It would be best if they switched to the linear bearing that is a “plain” bearing style with no actual moving parts. It ends up essentially silent and also removes the wear issues that the BB design above can lead to in some cases.
That said, not all fore-aft motion is like that or as noisy. The InsideRide system for their rollers and E-Flex are pure wheel bearings as a different approach and don’t add any real noise IMO.
Would instantly buy InsideRide E-Flex if it would be trainer independent and working with my Neo 
Yeah, I have a “hack” I started years ago for that case, but have not finished it. Essentially, uses the stock E-Flex front end, with my won rear section for the Neo. I need a few hours in an afternoon to finish it, but expect it will work as intended. I can share more info if you were really tempted to head in the DIY direction.
Could be an option. Would be nice if you had a pic for my better understanding. (Other option might be to buy kicker at actual price)
I will try to snag a pic tonight.
No shipping outside US and Canada. Bummer.
Oh, I always forget about that. Lame sauce.
I literally dug out this thread to try and find out about the Pedivella Rocca for the Kickr.
Can I get some feedback on how well these ‘rear only’ plates work and if they deliver the comfort benefits? I had even considered the stupid expensive Kickr Axis feet as a space saving option but mixed reviews suggest they make little difference in reality? My goal is comfort and eliminating as much of that soreness we are probably all familiar with once you’ve been on the trainer for a little while.
I’m very tight on space with the trainer wedged between the rear of my ‘garage queen’ car and my workbench. A full length rocker plate makes access to the workspace pretty much impossible but this type of plate under the Kickr would be perfect.
Thanks
- Rear only plates work great. My original design and from 2015 and the ones I used for over 3 years were this way. It works great and you can get all the basic benefits from them. I have a Full vs Rear section that covers the main points of interest.
- Indeed, the Axis feet are no better than a thick training mat or other compressible foam options. There are cheaper DIY options if you want to do a minimalist version to add some motion.
- Depending on your real needs, you may gain enough comfort from DIY version like the foam blocks or inflatable balance pods. I snagged a few pics from the FB group for reference in a related thread. Those are just some ideas to show that even simple options are possible and rewarding for many riders. I am more than happy to help you try any and all DIY hacks if you’d like some inspiration and help.
For the Kickr, I would go with the InsideRide E-Flex. I used that when I had my Kickr, and I loved that combination
I agree, the E-Flex is great for the Kickr. Not sure it can fit with his needs, but the small footprint and fact that it is actually 2 separate sections may allow use without the limit that seems his concern.
Thanks - It does look great, but…$$$$$ and I’m in the UK so no option anyway 
I’ll check out Chads DIY options and see what I can find.
Thanks Chad - AGAIN!!
Lots of food for thought here - my key need is simply to improve comfort for those longer rides. I don’t plan on spending hours but 2 be able to do 2hrs in comfort during periods of bad weather would be a huge win. I like the idea of possible DIY options as I don’t want to throw money at it ideally.
I’ll check out your links and no doubt be back with more questions in time as well 
Here are some quick pics and description of the next step I need to take to finish it.
-
The main device is a simple plate that supports the Neo with a minimal footprint that matches the Neo.
-
The underside includes two simple casters. They function as the lateral rocking pivot axis, and they also allow fore-aft motion.
-
The missing piece is a simple extension that will start at the back side of the front section and extend to become the foundation at the rear (red rectangle). From there, install a section of cut pipe (like PVC) that serves as the “track” for the casters on the trainer support (yellow arcs and lines).
-
That system relies on the fore-aft centering from the front section springs, as well as the steering and lean control from the front as well. My hack is serving the same purpose as the regular E-Flex Kickr version, but I am just removing the centering since that is already present at the front.
-
In essence, this could be done with any other trainer that isn’t a Kickr. Exact height from the casters and track with it’s connecting support, needs be high enough to allow the width of the deck to not contact in a lean earlier than the rider wants. I have done some rough setup and think I have it right, but need to finish the build to confirm actual function.
Does this design not need the inflatable balls?
