hypershpere ring on my RF works worse than on my NT

[Neo.X]

A month ago, I put hypershpere ring on my NT. The result is fantastic. The keyboard is much quieter, feels more sturdy, and most important, the typing feel doesn’t change much. The travel distance is almost the same.

With the successfully experience, I order more rings and put them on my RF. Although it does make the keyboard much quieter, it reduces key travel distance significantly. I ends up taking them off.

One thing I notice it that with the ring on my NT, the sound of downstoke doesn't change much. But with the ring on my RF, the downstroke also becomes much quieter. I think it's becuase the key travel distance is reduced.

Another thing is the ring is looser on the RF stem than on the NT stem. It's actually too loose on RF stem that it will fall out by itself. I am wondering if that makes the difference.

Anyone thoughts?
Thanks

Could be quality of batches too

lol anyone can confirm this?  I'm about to mod my RealForce but now I'm scared.  >_____>

its not a permanent mod... don't be scared.

yeah if you can be bothered to open them both up or if you have some leftovers from each batch, it sounds like they could have different dimensions. topre sliders in both board should have the same diameter as they both have to sit in their slider housings with little tolerance, so if the second set of rings seems looser then it implies that they're different.

I will try the same rings on my HHKB to see if they fits well.

Okay I took a leap of faith and modded my RealForce 104UW (since I ordered the rings a while back already).

So off the bat I will say YES IT DOES REDUCE TRAVEL.

Ring is about 0.5 mm thick so yes it does reduce travel.  Is it noticeable?  YES.  Will you hate it?  DEPENDS.

Okay I'd imagine Topre housing is all the same and same travel, so the only difference is keycaps, kind of like Cherry Profile vs OEM Profile kind of difference.

I don't own Novatouch, but I will assume it has the tallest keycaps.  So it FEELS like it travel more, then you reduce a tiny bit, not much difference.

Secondly we have RealForce, it has probably regular height keycaps.  You reduce it a tiny bit, I'd say it's still not bad, it's about same height as stock Leopold FC660C.

Now we're looking at Leopold FC660C, I think to be honest, in stock form this already has pretty shallow keycaps and is already pretty quiet, so modding it I don't think it help much in sound and it make it feel very shallow afterwards.

So in summary, yes it does reduce travel, you'll like it or hate it depending on keyboard.

Novatouch - High Travel, so modding is a go.

RealForce - Medium Travel, personally I really like it after I mod it even though OP doesn't like it.  So I'll say debatable.

Leopold FC660C - Short Travel, Leopold profile is kind of like Cherry profile.  So I think after modding it it's too short, I actually like stock form better.  Doesn't recommend modding.

Type Heaven - Short Travel, I own this but I haven't mod it yet.  Though based on my experience with FC660C I'd say probably not a good idea to mod it.

HHKB - Doesn't own it, someone can comment on it.

Now if we ignore key travel, just purely on sound and feel.  The ring actually tighten the space and make it feel more solid, and the reduced sound is amazing.

So if key travel isn't an issue, I HIGHLY RECOMMEND silent Topre.

Yes let us know what you find afterwards.
