Just had a very frustrating evening 🤣
Got my filmore valves on as hadnt read anywhere they weren’t compatible
Managed to get them inflated no problem with the Rimpacts in, how ever no bueno when trying to release air, simply hasn’t got any space to remove the air, had to undo the screw that secures it on, and manually push the actual valve up to release air, no use when trying to set pressures for a ride
So removed them ( good practice for getting the tyre unseated at least)
Put some Peaty’s valves on I had lying around and looking at base of valve i thought should be fine - but no these buggers won’t allow the air through enough to even seat them 😌 and no they weren’t clogged I made sure before to check that
So had to remove them again and remove the bloody rimpacts
So I can’t physically see what I could be doing wrong?
Do I just need to get some rimpact valves instead? Very frustrating evening 🤣
Rimpact have their very own valve, if you bought them directly from them it should have come in the box. Even using their valves I had the issue you had when trying to release air and it was spewing sealant!
Slightly different issue but advice from Rimpact:
It sounds like the insert is stopping the sealant from moving around the tyre after you injected it. Two solutions would be to go ride it to get the sealant out of the cavity and into the tyre by hitting some decent compressions, or let all the sealant come back out and let the tyre down.
If you do the second, once the tyre is flat, manipulate the tyre and insert around the valve area, which should release any sealant trapped between the insert and the rim/ valve. Having the valve orientated at the top of the wheel will also help as gravity will help drain any pools of sealant. The aim is to roll the tyre back and forth laterally over the rim to tease the insert off of the valve and let it relax its positioning.
Oh bugger thanks for reply so even with their own valves there’s still a bit of a issue - I’m meticulous with air pressures so I really do need it to be able to set them perfectly
Such a shame my filmore valves won’t work, annoying as they went up fine with them, but releasing the air was not even possible at all unless I undid the valve from the base and then basically lost all pressure
Maybe over thinking it and just get some rimpact valves and hope it’s easy to add/remove air and use my digital gauge which is critical to me
The Cushcore valves have a hole at 90 degrees to the main hole at the bottom of the valve so that the air escapes sideways underneath the insert, this allows the air to inter and exit as the insert doesn't block the hole. You may be able to achiev the same effect by slotting the bottom of the valve. Either that or buy Cushcore valves - they're not cheap mind.
Either that or punch a hole in the appropriate place on the insert. This might be hard to always line up though.
Surprised Rimpact don't have a similar option.
Did doing those things they suggested get it working? And can you now easily fill/remove air when needed?
Speeder - I think the rimpact ones look similar tbh , but the Peatys ones I used have a cut out on them too so god knows
Yeh did think about cutting a hole in the rimpact but would be hard line up and probably end up clogging with sealant over time
Think I bought the Uberbike ones
They have a cross cut into the base so sealant comes out at 4 angles
Surprised Rimpact don’t have a similar option.
They do, and they work just as well. Rimpact insert don't have the channels to allow the sealant to flow from under the insert to the gap between the tyre and insert as per cushcores. I've also found that the Rimpacts soak up a fair bit of sealant so I generally add some extra.

Rimpact sell the Peaty's valves as an optional upgrade, should work fine
I've had a similar issue with a Rimpact Pro.
I couldn't even get the sealant to go in, it just kept squirting back out when I took the injector off the valve. Had to break the bead again to get the sealant in.
Once it's been ridden for a while they stretch out a bit and you can get air in and out no problem.
Standard Rimpacts have been fine for me from the off.
All used with Rimpact valves.
Cool thanks for the info folks sounds like the rimpact valves are the way to go
No issues with using Rimpacts own valves here, just don't try putting Stans race through them!!
The rimpact valves do have a cut or hole to get the air in/out at 90°, however I have found that they too are pretty restrictive on airflow with an insert fitted. They're OK in terms of getting a tyre on (or off) but they make the equalisation of pressure between pump and tyre very slow, so make it more time consuming to set pressure with a gauge. They aren't the end of the world but I'd like to find something better, ideally.
I have found valves that aren't designed for use with an insert not to be fit for purpose with an insert. Not every time but soon enough I think you'll have trouble.
I’ve got used to the filmore valves which are incredible, super easy inflate tubeless and easy to maintain pressures with a digital gauge and hand pump
Must admit I’m tempted not bother putting them back in to be honest, would be nigh on impossible remove the tyre in the wild too
Not sure the benefits will outweigh the niggles for me

sorry just saw this - yep didnt work for me - even with my big old joe blow mountain track pump i couldnt get the air in, it just rebounded the air back through the pump
looking at those valves they do have a escape for air on the side too, so not much different than the rimpact ones?
either way didnt work - now making me more reluctant to even buy the rimpact ones and just not bother
I’d probably get in touch with Rimpact. You’ve spent extra to get the ‘better’ valves and it’s not working, think I’d ask for some free standard ones

Peaty's valves worked fine for me with rimpact pro..
Two bikes with Rimpact Pro and their own valves.
Had the air release issue with my first set, but that was because the bike shop had used that god awful Peaty’s sealant. Was so thick and claggy, the air only came out in small amounts. Pushed the valves through like you had to, cleaned everything out and replaced with Stan’s and no issues since. Liked them that much I added them to the ebike using Stan’s from the start and they’ve been perfect.
For Peaty’s valves, I think they only recommend the MK2 version.
interesting stuff - they have actually come back to me and said my filmore reserve valves should work albeit they havent tested but plenty of users have - i have no idea how that could work tbh -
i used stans sealant, everything was clean - they went up a breeze so the air was getting in fine on the reserves, but getting out it just did nothing and that was both wheels, i cant see how the design would allow it work tbh
ill try the rimpact valves for the sakes of 15 quid as hopefully it will just work then
I used Uberbike valves on the little bike, worked fine.
Have nukeproof valves on the big bike, but haven’t done the rimpact yet. Side holes on the base as per uberbike/Peatys etc so should work fine too.
Remember that there is also another good option for posh high flow valves

just a heads up for anyone in the future
just get the rimpacts valves - the airflow is 100% better than with peatys - i can now use my pump much easier and read digital gauge pressures a hell of a lot more easier too - just get the valves when you purchase the rimpacts, totally worth it!
Yep, I have their valves on one set of wheels and they work fine.
Other ones I just use normal tubeless valves and sometimes have to remove a valve core and poke a thin allen key up the valve stem to release a bit of air.
😀
If you are in a pinch you can cross drill some standard valves so they work with inserts
