@mcneese.chad since the SBR Rocker Pro has the rubber bottom and top, any reason to run a mat under the rocker in your opinion? (sound is the same as when it was on the mat). I moved the mat under my yoga mat for additional comfort and to get away from the cold cement. I moved the rocker once, just to center it but doubt I’ll move it from where it is.
I don’t think you need the separate mat at all now.
Chad thanks for all of your advocacy and free advice for making our indoor experience better.
I want a rocker plate badly, but my basement ceiling is about 6’1" tall. If I sit up on my bike, my head hits the ceiling.
Most rocker plates seem to add 3-4" … do you have any ideas on something with less profile? I’m using a KICKR Core.
I’m even considering opening up my ceiling drywall and letting my head rise up between the joists…
I’m happy to help. I think trainer motion is something worthy of more time and research to improve the indoor experience.
The Core has an option to remove the horizontal legs. I envision using the mounting holes and plate to attach a pivot for rocking.
I haven’t spent the time to really figure it out, but it might allow adding motion with minimal height increase.
I can try to come up with something more specific if you have access to some tools and are willing to tinker.
i built a rocker plate for 26 dollars!!! One cut and six screws done!! Cant image riding without it now

Yes I have wondered the same thing - is there a way to take advantage of the mounting holes?
I have tools and and definitely willing to tinker.
Ok. Can you snap a picture of the leg and upright connection for me? I just want a closer view to try and come up with something for you to try.
Yeah, that sounds like a good start. Let’s build from that concept.
So I set up the Rockr the day before, used a bike pump with no gauge and my iphone to level it. Rode the next day with no issues. Got the hand pump with gauge last night (not too impressive but 20 bucks…) and the gauge reads 3psi on both side. I didn’t mess with it, called it good. (oh, and nice thing not to have to add weight…)
How often to you check the air if you do?
I check about every two weeks or if I notice it feels too loose.
I also like to add about 0.5 psi when I have particularly hard workouts, so I get more support. I don’t like to have to focus too much on balance for Ramp tests and stuff at the top end of VO2 and above.
I use 3.0 psi for most riding and it is what feels more like riding outside for me.
I have Speedplay pedals, so I set calendar reminders to grease the cleats every two weeks and spindles every four weeks, so I’ll add check the air every two weeks.
Hi Chad,
I have built my RockitLauncher (many thanks for the design!) but I have yet to finish the “resistance” part. I was wondering how you stabilize those balls between the two plates.
Thanks!
With inflatable balls 4" [100mm] or larger in diameter, they just hold themselves in from the friction to the plates.
I start with the only partially inflated and position them where I want. Make sure to leave access to the inflation hole. Then add pressure to level the top deck and adjust for user preference.
Do you have an idea of how we could create cushioning? I can’t really conceptualize anything that might mount to the bottom of the ends of the dowels.
I have just a simple concept and have not taken the time to get it more worked out yet. Sorry for the delay. Juggling several active projects (work and home) at the moment.
No worries Chad! I greatly appreciate any help!

Decided to use stuff in my paincave to test if rocking would be better, here i am 6 weeks later finishing up ssbmv1 and i have no need to upgrade or change my setup.
You will need. 
-Hammer H2
-An outdated book of paramedicine for front wheel
-2x specialized storm tires one new and other a bit used
-A training mat with some spring to it!
-A bubble level for tuning
Took a bit of fiddling to get it adjusted, cannot say it has a road like feel but its silent and provides stiff rocking that makes longer indoot rides comfortable.
Ha, the proof is in the pudding. Glad you tried something and that it works. Its darned close to the super simple versions. I’d like to show people for the basic testing and proof of concept to see how they like motion.
Props and happy rocking. 
Hey Chad,
I’m imagining the Core mounted on top of half-circle dowel rods, with the hinge mechanism underneath.
What if I used your rockit launcher hinge mechanism with 1x4s, but excluded the top 5/8 ply board (to be replaced by the kickr core with wood half-circle wood rods), and excluded the horizontal 1x4s (Part 2 on your Rockit launcher PDF)?
Foam springs could be mounted underneath the wood half-circle rods to compress directly onto my floor.
The potential issues would be:
-
having enough space on the dowel rods to mound hinges
-
less space to mount rubber feet which would lead to unwanted trainer movement. This would be the benefit of having the horizontal 1x4s, but it would raise the height of the unit by ~0.75 inches…
Any thoughts? Thanks Chad!
