Just put these on my wheels but wondering if the pink sticker around the base of the valve on the outside of the rim is needed?

Not "needed" to function per se, but greatly limits rattling

You know this is funny, it's way too ugly to put on the outside so I actually put them on the inside to stop rattle and reinforce the valve stem area.
It works fine and no issues this way at all- I thought this was the way it was supposed to be, since there were no instructions.
I'm running latex currently but that's how i set up tpu.

Do you stick then to the rim or the tube?

I put them on the rim. Honestly, don't think they would stick to tube b/c the tube will flex quite a bit w/ deflating and inflating.

I'm not having much luck with my ride now tubes. Managed to tear 2 fitting them, anyway thought all was fine went for a little ride and was happy, just went to take my bike out now baring in mind it hasn't been used for 6weeks both tyres were completely flat.
Pumped them both up, done some other bits then noticed my front was already flat again. So popped it out and fitted a new tube. Ride for an hour and now that is holding air fine but the rear has lost a noticeable amount of air, I reckon another 15mins and it'd have been too flat to ride.
I will try my last tube now in the rear but not a great start that's 2tubes in 90mins of riding

Have you checked if there is something in your tires?

Yes checked them and fine however back has gone that over night so will have to replace that. Not sure whether to order some more of these to keep trying or go back to butyl to be honest. Wanted to try latex but can't find a tube for 30v tyres that with a 60mm valve unless anyone has any pointers to one

Can you repair a puncture with normal glue less patches like the park tool ones,or do you need Tpu patches?
A few pages back I did some testing and found the park patches are the absolute best for TPU tubes. You need to clean the tube with alcohol before you put the patch on.
Have you checked if they were still stuck after a few hundred miles? That's the problem when using them on latex or butyl tubes. The edges would peel up and the patch would leak after a while, which is why everyone called them a temporary patch.

After a few thousand miles they are on, permanently.
They cannot be removed even if you wanted to without tearing a hole in the tube.

I have 24mm internal rim width and currently 32mm tires, I'm thinking I should probably go for the 39g model because the 36g model tops out at 32mm, and the 32mm tires measure at presumably 34mm (not that I measured it), what do folks think? If I move to 28mm tires I could go for the 36g though. And the 39g ones are 1€ more per tube.

A week ago I received 4 TPU 36g RideNow inners. Mounted yesterday 2 inners on a set of wheel with 21mm innerwidth.
Tires are Tufo Prima 25mm measuring 28,3mm
Mouting was easy for both sides back/front.
No isseus with leaking and they still hold pressure well.
So far so good.

At another wheelset I have mounted a TPU as latex replacement. It runs already for more than 5k km's

I started using Ridenow TPU last year on the road bike. Had an issue with a bad valve stem about a month after installing, so I replaced with another Ridenow, and completed the season without incident. Made the stupid mistake of inserting into my (narrower) training tire this winter, obviously damaging it slightly resulting in a catastrophic BANG! a couple of minutes later. Have no apprehensions about continuing to use on the road, with the wider and more supple tire choices I make for outdoor riding. I do carry butyl in the saddle bag for roadside repair, as they're less fussy when it comes to installation, similar to what others choose to do with latex.

Thinking about going with the wider 45g Ridenow tubes for the gravel bike, saving around 115g per wheel vs. butyl. At roughly $6 USD each, seems like a no-brainer.
