I noticed a bit of noise from the rear section.
I need to investigate and find the origin. I will try to check with IR on any recommendations
Thanks Chad. Iām pretty sure itās the rails clunking onto the base as I rock. I took everything apart and was able to replicate the sound. Applied some grease to pivot (but I donāt think that was the issue), restricted the rock just a tad with the slider, then taped a piece of think packing foam underneath to act as a dampener. Havenāt ridden it yet, but we will see.

Thank you! This small change made a HUGE difference in the way the E-Flex feels and I like it so much better with no fore-aft springs on the front.

NICE! Glad it helped. 
I think it varies from person to person, but I find that the E-Flex default is quite strong and leads me into an odd oscillation. The looser setting (rear only engaged) moves a lot more, but feels far more natural and I donāt get that odd force feedback.

Not a typical squeaking sound for me but more like a metal on metal sound resonating through the frame (I run an old Caad8 ALU frame on the trainer).
I find if I reseat the rear axle back on the trainer again and ensure its really tightly secured it goes away for around 20 hours then returns.
Anyone use this with the most recent kickr v 5?
Iām having issues with a lean to the right and have had to lockout the fork platform. I contact IR and they recommended using the soft setting for the plate support and changing the center arm from 3.5 in to 2.75 in.
This helped but still leaning which becomes a distraction during a session.

Are you on a level surface?
Yes. I set it up level both vertically and horizontally. Iām assuming the right tilt is from the plate. Iām not sure what to do, I was hoping the fix on setup from IR would handle the issue. I want to like this product but canāt live with additional distraction while on the trainer.
Not sure what else to offer without more info. Any chance you can snap some pics to share from a couple different angles (square from front and rear, as well as some general angles) to see if something jumps out.
Pics are above. I sent the same pics to IR and they confirmed setup was correct. Their explanation of the tilt was due to user being the source of the tilt, which is possible. But why change the setup on the central bar length and switch to the soft plate setting?
Plus, the tilt was better when I changed from the original setup insurrections. My hunch is that it has to do with the plate and it doesnāt balance out the trainer and still over compensates to the right - hence the lean. Any other input that can make this work is appreciated otherwise Iāll return it.

Ok, I think I have a good guess on the issue.
The Kickr V5 got the new Axis feet for adding a bit of motion. I donāt have one to compare but would guess that the rear foot under the Kickr is taller on the new V5 than the older Kickrs without any motion.
So, if the rear foot is taller, and the leaf spring bar sits in the same spot, it would lead to more lean to the right side than is intended (per the original design using the rigid Kicker rear foot).
Does that make sense?
It seem right considering the improvements youāve seen have come from decreasing the leaf spring force (flipped bar to ālightā setting and the more rearward shift of trainer install).
See if that makes sense, and we can try to come up with a solution. One quick idea is to remove the Axis rear foot. And add a rigid spacer instead, that is the same height of the rigid Kickr feet from the old models. I can get you that thickness if you want to try that option.
Ultimately, if Iām right, Inside Ride will need to come up with a variation on their solution to handle this model difference.
That all makes perfect sense.
Seems like IR is aware of the differences in the model years and trying to come up with a solution. The rear foot on my kickr measures 30mm including the plastic cover and metal base and approx 25 mm without the metal base.
Mine is about 20mm for just the foot (not including the metal plate). That difference could easily lead to your issue then.
Sounds like this is all headed in the right direction now.

Yes, that 5mm difference in the foot looks to be the cause.
Thereās got to be a better fix than changing the center arm length and flipping the plate. Maybe IR can provide some additional options rather than user being the source of the issue.
I am guessing they just didnāt realize the difference until now. Without having one on hand, it would be hard to know what changed and by how much.
The designed the E-Flex based on the original design that fit 4 trainers. Wahoo changed the design and now IR has to adapt. Sucks that you seem to have lucked out and been the first to experience or recognize the issue. But I have no doubt they will come up with a workable solution.
I could see them having you remove the Axis foot and them supply a new spacer at the right thick (like the rigid feet). But we will see what the come up with for you and all other K V5 users, since they now have to handle it one way or another.
What I got back from IR:
First, we are aware of the differences with the Kickr V5.
We have worked with several V5 customers to arrive at the current setup combination. So far, everything has worked out fine. Weāll also point out that the unknown problem reported by these users wasnāt unwanted lean, it was a ride height issue, solved by sliding the Kickr back to the 2.75 location.
The extra height of the V5 foot works out right with the soft position of the support arm, which is why itās now the standard position for the V5 and also why your condition improved when you changed it.
As you still have unexplained lean, we have a simple test to determine a solution.
You can swing out the left hand Kickr leg as a counter-weight to compensate for the rightward lean. If that is not enough, you can add weight to the leg until the underlying tilt is eliminated. Once the proper amount of weight is discovered, we can make changes to the support arm to match the counterweight.

Just curious if anyone with an eflex has done a return? Iāve got a young family and not a lot of spare time and energy to go down a rabbit hole of being a v5 kickr guinea pig. After having the eflex for a week itās been a lot more than āplug and play,ā despite Inside Rides timeliness and communication.
Looks like Inside Ride just added official support for the Kickr Core trainer along with the prior Kickr models. Not a ton of info, but seems to be that you buy the same E-Flex unit either way, and mount appropriately. I will update as I learn more.
