I initially set out to provide the lowest cost, highest value, rocker plates to the masses because (at the time) the highest functioning rocker plates were $1,000+ USD. With inspiration from the Rocker Plates Facebook group I came up with the V1 of the Ride South rocker plate which I released the plans for free. I then started working on a V2 version which I had planned to sell for the low cost of $350 USD.
Fast forward to now and few dozen rocker plates sold and I just do not have the time to support the side project coupled with the fact that multiple “companies” have taken my plans and are now selling them as their own with very little modification. I have decided to just release all of the plans and source files and that is what this webpage is for.
Parts List
In the manner of transparency, the links in the below table are mostly affiliate links where applicable. It costs you nothing to click them and helps me justify making more things to release for free in the future. (also worth noting, these are all parts required for the project and not random crap I am trying to sell you.)

Notes
- If you decide to go with SCS20UU bearings YOU WILL NEED RISERS.

F.A.Q.
- Does this rocker plate have fore/aft & side to side movement?
yes. - What is the difference between SBR20UU and SCS20UU?
mounting bolt pattern and stack height of bearing.
Love the video and instructions. I noticed a bunch of the affiliate links are busted and would love for you to get something from all this work. Do you have new links or recommendations for substitutions?
Aaron,
Thanks! I’m working on converting everything over to this web page (away from the excel sheet that gets stagnant) and getting all of the links updated. I should have them done by this weekend.
Awesome video and instructions, I am also looking to use your build and instructions and would love to see the updated parts list if possible. Trying to see if I am able to get all the required parts here in Miami, FL. Was about to go out and purchase a pre-made rocker plate when I stumbled upon your video. I am of the mindset that if I can build it on the cheap and still get the desired functionality than why not.
I’ve went thru the parts list and the only thing I cannot find is the 20mm Linear Rod at 1400mm or 55″ long. I will continue looking.
I am assuming a 1200mm linear bearing will not work with this design? There is a kit currently listed on Amazon that includes (4) bearings, (2) 20mm x 1200mm linear rods, and (4) linear rod supports for $40.
Paul,
You cannot go shorter on my specific design as the linear rod mounts are positioned for the 1400mm, but you can go longer, you’ll just have some rod sticking out the front or back. Hope that helps.
I thought it would be an issue, doesn’t hurt to check. I’ve been shopping around for linear rod since the amazon one is out of stock, have you tried any of the hollow rods?
Also, on the counter sunk holes, I am assuming you put a washer in before the cap screw, what is the depth of the larger hole countersink?
The hollow rods should work just fine as long as they are hardened. I was actually going to order those when I ran out of the solid linear rod stock I have as it would reduce the shipping weight by quite a bit. I did use washers on the counter sunk holes which are 7.5mm deep. On my latest design I skipped the washers and flat head bolts and used tapered head bolts to avoid using washers.
Also, if you’re in the DFW I have some 1400mm rods in stock I could sell separate. It probably wouldn’t be cost effective to ship one.
I will look around for some hollow ones, unfortunately I thought they would be cheaper but look to be more expensive. I did find a 20mm x 1500 mm non-hollow rod at Grainger for under $70 but it is not hardened. Everything I am finding else where are sold in pairs so they are about $160/$170 ish. Too bad I am not in in the DFW area, I am up in New England, sourcing a cheap rod may be the sticking point for this build.
by tapered head bolts, you are using something like this? https://www.amazon.com/M6-1-0-Socket-Screws-Alloy-Steel/dp/B07S51Z6JS/ref=sr_1_6?keywords=m6-1+x+30mm+screw&qid=1679508538&s=industrial&sr=1-6
I’d sell you one for 40$; unfortunately, the shipping on one is going to be ridiculously high as they are very heavy and long. Those are the type of bolts I migrated to.
If anyone is looking I finally found 20mm x 60” rods decently priced on vxb.com for $57 shipped from the west coast to east coast.
Hi is there any chance that you could send me the files to my email account please
I’m in Fort Worth and will take you up on the offer for the rod for $40. Please email me.
what is the center line on the V1 top plate? decorative of integral to the design?
It is for centering your trainer/bike. Even weight distribution is important to the mechanics of the plate. If you are not evenly distributed you will feel the difference pretty quickly.
gotcha, so its just a shallow groove for indicating the center. Just asking incase the guy operating the CNC router has a question when he is making the cuts.
