Random thought - If carpet and non-level flooring is a problem, how about a couple platforms with spike feet like one would use under audio speakers or vibration sensitive equipment? That might make for better stability and allow for leveling.
Yes, but those sit on top of the carpet. Was thinking that Spikes would poke through and get to solid substrate. $0.02
OK, got it.
What kind of fancy carpet do you think I have? 
See that tile in the middle? I have a few of those. I tried it with those under the feet and base. (amazing values @ $1ea at Menards btw)
Question for the @mcneese.chad and the group:
When my 2018 Kickr is mounted to my E-Flex, and the bike is not attached, I feel a noticeable “clunk”, or detent, in the middle of the fore-aft movement when I slide the Kickr forward and backward by the Kickr’s handle. Is this normal?
I have the leaf spring in the correct direction for a 2018 Kickr and my center support arm extends 90mm beyond the front clamp.
I get that too. I haven’t totally dug into it, but here is a good guess.
Unloaded fore-aft motion (no bike and rider) allows the internal slide to lift and rotate slightly in the tracks. When you move the slide enough to hit the spring resistance (o-rings), the off-center location of the spring attachment vs the center of the slides leads to a tilt.
The clunk you hear and feel is the internal slide twisting and hitting the other side of the tube, inside.
Once you actually load the setup, there no chance you can twist the slide, so there is no clunk in that case.
Does that make sense?
That makes perfect sense. Thank you!
I’ve liked these a lot! Made this indoor season (year?) a lot more bearable. Sad that I have to relocate for a work for a bit and can’t bring them with me.
The wheels inside the unit are plastic. It’s possible one is dented or there’s soemthing in the tube. You can pull the end off and have a look. Probably the quickest way is to pull the two rubber bands off and just look/feel in the channel.
It could also just be the whole unit rocking fore/aft a bit. Not a big deal.
Has anyone removed the little sticky ‘feet’ that come on the bottom of the unit (both parts, front and rear)? A couple of mine keep sliding (so that half is under the unit and half is exposed) and it’s bugging me. Every time my knee starts to hurt I look down and realize ‘oh yeah, that foot had edged out again’. Then I fix it and it’s fine until it starts to work it’s way out again. I don’t think they are adding anything to the performance, I assume that they were added to protect people’s floors.
Any thoughts?
Mine are in place, but I am on carpet, that absorbs the rubber height and sits on the aluminum tubes anyway.
Typically, I’d like to have a rubber foot like that, so I’d either get some new double-stick tape or new feet to attach.
Pads haven’t moved on mine, perhaps because of the mat? We have wood floors in the house, and all chairs and furniture have felt pads. So it’s the sort of thing that I routinely look at when vacuuming the feet on kitchen chairs or moving the InsideRide off/on the mat. Definitely no movement on my InsideRide in the garage.
Oh yeah for sure, your mat is keeping those perfectly in place. I’ve just got a little utility mat, no real padding.
For what it’s worth, upon further inspection taking the sticky feet off altogether is a bad idea. There are a couple of screw heads on the underside that would then be contacting the floor. Probably fine on a soft surface, but the whole thing would be unstable on a hard surface.
I’ve had these for about a year and love them, but recently I’ve noticed a “squeaking” and I’m certain it’s not the drivetrain. Has anyone applied lube or grease to pivot points on this things to help with this?
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. I’m pretty sure it’s 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 don’t 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. Haven’t 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 don’t get that odd force feedback.
