Best TPU tube brand

[coffeebreak]

Looks like RideNow have a version with a pink (alloy?) stem with a black base (I assume it's some kind of material covering the stem to help with durability). Has anyone tried these? Are they newer then the white stem version?

I have those. The pink section is alloy indeed and in contrast to some other TPU tubes these have removable valve core too. Additionally these also have a tightening ring that plastic stem TPUs don't have.  Even the cap is metal and color matched. These weigh 40 grams  so slightly heftier but I like these better.

Yes, they are the new version. I have these and they seem to be higher quality than the valve on the white version.

And the pink valve is very cute

I've noticed those "new" RideNows with the allow stems, but avoided them because why mess with success? My limited experience with tpu tubes was that if the tube was going to have an issue it would be an issue with the valve or the bonding around the valve. But, if you guys say it seems improved, then I guess my next lot will be of the "new" style.

I guess RideNow seems to have their act together a little more than some of the others, I've noticed. If they say it's an improvement, I guess you gotta trust them.

my favorite tpu tube is the Cyclami. You get a lot of tubes for $4usd.

Are they better now? I bought the 1st gen Cyclami tubes with non replaceable valve core and they all started leaking air slowly for no apparent reason. I couldn’t find where. So I avoided them ever since. Their repair patches are great though.

I can compare with traditional butyl tubes, tpu (Cyclami included) tends to hold air longer than the butyl tubes.

if its plastic stem, check at valvecore;
other brands using plastic stem may suffer this too, including ridenow, if your pump head is the clip-secure type n you yank off the head pulling a bit the core once you done pumping

i just ordered ofbondage 85v to try.
so far i have tried:
- revoloop ultra 60v
- ridenow 1st gen 36g 45v
- ridenow 2nd gen 24g 45v, 65v, 85v
- thinkrider 85v

thinkrider 85v lenght is measurement from base to core tip, but ridenow measures the valvestem itself excluding the core tip.
using on my 86mm rear rim, i dont need to use extender when using ridenow 85v
*i can bareley get away not using extender on thinkrider 85v, but i need to hold my pump head as its borederline gripping the core

Tested Ridenow last year alot of flats went back to butyl to be sure. :s
If the new version is better maybe I should try them

Had ordered ofbondage 85v with gold valve, as my first tpu tube.
It started it leak due to bad interface with the valve . Had used it for less than 200Ks.

Has anyone successfully repaired a tube with leaky valve? ( the seam at the valve insert isn't done well thus bottom of valve leaks air in high pressure or upon bending the valve )
Worst case, I know have a sacrificial tube for puncture repairs.

Currently on offbondage regular black/silver values, hoping these last better.

My experience with all sorts of different iterations of these TPU tubes from Cyclami, Ridenow and now also Offbondage is: If the valve is leaking, there seems to be little you can do about it. I certainly haven't been able to stop it. Punctures however can be repaired reliably with most of them with good patches, like the Cyclami ones. In fact I'm currently riding a Ridenow tube with 2 patches on it that works just fine. But if the valve stem is giving me trouble, I usually dump them. But I only really had leaky valves with the first gen of Ridenow and Cyclami tubes.

The inner tubes on the market today are too thin. We bought some stock inner tubes that were 19mm thicker than the competition but weighed only 45 grams. From an initial pressure of 100 psi, the air leakage was about 2 to 3 psi per day, while the competition leaked 5 to 10 psi per day.

using Cyclami 26g 60mm metal-presta valve here...
positive experience with it... tire is ultrasport25c and runs more than 4600kms never replace and lucky without any puncture... i just need to pump once a week to 6bar and i can ride for 3-4consecutive days...
my other set with tire of kenda28c max 80psi and same need to pump once a week...

negative experience... all from my kenda28c set
got 1leak on the valve as i tighten much the nut...
got 1blown up due to the weak rim tape
got 1puncture and put a patch but not used until now, just my reserve...

still my go to tube brand since it has metal valve which i think it will last longer than the plastic valves...

I use Ride Now. I bought a case of them because I like to have spares.

I have tried ThinkRider, my success was spotty. Two flats.

Just a quick note, I learned the hard way that Topeak fly paper glueless patches work really well on TPU tubes. It's been 4 days since I punctured and did a roadside repair with them. Holding very well without losing air more than what is usual for TPU tubes. Just scuff up the puncture site gently to make adhesion better and that's it.

I use RideNow, 36 gram version, great value for the price. I've done around 7k on a pair, only puncturing once due to my tire being sliced open. Other than that, they are rock solid. They do loose pressure a bit quick than I would like, but I pump my tires before almost every ride anyway, so not a big deal.
