TPU tubes are extremely fragile when it comes to size if it says 32C max, you would not blow past that AT ALL. Heck for safe side, stay on 30C.
For 40mm tire you need the gravel up to 45C tube.

Is it me or do they just feel different. I just replaced my butyl tubes as I was waiting to get a big enough puncture to justify getting rid of them. I replaced them with the Ridenow that I had waiting and I swear the tire at the same pressure with the ridenow is more forgiving. Has anyone else felt this?

You're not crazy. They are a little more comfortable than butyl

Do these tubes still lose air randomly without punctures?
Went to ride yesterday and found that the rear wheel had lost about 20psi. No problem with the front.
Filled the rear up, rode 20 miles, no problem.
Woke up this morning, and it's completely flat.
I have to assume it's a puncture or failure somewhere, since the front wheel hasn't lost air - but wanted to make sure it's. not part of living with these RideNow tubes.

Punture. They don't randomly loose air (like tubeless does occasionally).

Possible loose valve. I've had a couple do this.

You mean the valve core is loose?
Edit: nvm. I see that the cores are not removable

I think the cores were removable on early RideNow's and there were some valve leakage issues. They're now glued in permanently.

You're wrong. Go back a few pages and read the posts.
They are still removable, but they use a loctite material to prevent them from coming loose, however, sometimes they can still leak when a pump is used that tightly grips/ crushes the loctite, it can fracture leading the a very slow leak.
They started using loctite to prevent people from over tightening the cores and cracking the stem.

I don't think that's my issue - I'm using a (very) old Joe Blow Sprint pump that is just gripping with rubber.
I pumped the tire up to 80psi, tightended the valve down, and put the core upside-down in water - no bubbles. So I guess the core isn't the problem.

Thanks for the correction Steve. I'm often wrong. I use both threadlock and bearing retainer from Loctite but somehow still think glue when I see the name...
Anyway, my early impressions after 900km riding Ridenows with carbon rim-brake wheels on moderately hilly terrain: they're fine.
I ride predominantly in the Surrey Hills / North Downs in the UK. I recently switched from aluminium Kinlin XR31 rims to Light Bicycle rim-brake carbon AR36's with 28mm GP5000's and fitted Ridenow tpu's at the same time. I'm 85kg and a cautious descender, so on the steeper, bendier and more poorly surfaced descents (Crocknorth, top of Whitedown Lane, Radnor Road down into Peaslake) I'm hauling on the brakes continually - though not continuously. Hills are short, so the tubes never experience 2 minutes plus of heat build up. I haven't experienced any issues with the Ridenows as yet. Examining one just now it appears to be in excellent condition. Incidentally, my 'pinch-flat while installing' days may now be over - the pink tubes really stand out against the tyres and rims, and the Light Bicycle AR36, GP5000 combination is installable without resorting to tyre levers.

I intended to import these tubes and distribute them, so had conversation with the company after using them for a few months. I had some teething issues such as leaky valves so they were warranted and they explained the issues they've encountered, and how they fixed them. Great product and a great bunch of people.

Anyone tried the Cyclami tpu tubes?
https://fr.aliexpress.com/item/10050041 ... dZtNTuk2ne
I heard they are made by the same company that makes the Ridenow tubes. They have the aluminum threaded valve stem and also reinforced seal.
I've seen a pic on a scale at 38gr. including valve cap, nut and elastic.

That's a puncture had the exact same issue with one of the Revoloop tubes, could never fine the leak because the hole is too small. Like I can pump it up all fine, go for a 50km ride but then leaving it overnight and it will be flat. In these cases you must change tube, good thing they are like 6 bucks a piece now rather than 25 two years ago...
About holding air, they hold up very well. I use 5.5 bar rear and 5 front, after a week of riding they drop somewhere around 0.5 to 0.8 bar

I saw a ridenow tube marketed at 24 gram on Ali the other day. I thought it was 36 (real life 32) and 19g as the only options
I think any TPU tube from Ali with plastic valve stem will be just fine. Green looks very good
