33g Inner Tube - Ridenow TPU

[openwheelracing]

Is it hard to find a hole on these tubes? A while back I had two that flatted over night but never found holes. I am afraid they would just randomly fail for no reason. Back then some mentioned the plastic valve was to blame but the new design is 1/3 plastic so I am not sure if that is any better...

I wonder if I actually had a puncture but just couldn't see the hole. Also, I hated them at 90 psi too rough, hurts my hands, but they feel fine below 70psi.

Are you running hookless rims?

No never.
But anyway I reached out via PandaPodium and they contacted Ridenow.
The mentioned the same about pinching but I almost certain that this wasnt the case as I rode the tube for 1000km and are very very carefull installing things.
I you once crashed due to a mechanic not properly installing a crank you get very wary easily
I mostly reached out to see if the tubes are suited for 28mm tires fitting on wide rims. As you know tires become pretty wide so wanted to be sure that its safe to use these. Not to blame things.
I didnt expect a response but the tpu tubes are tested with tires up to 32mm in 24gr version (according to RideNow) so for now I would still say they are structurally designed to be used in this configuration.
So likely it was a faulty tube or so maybe still pinched as you cant really look into the tire if still something got mangled up even being very careful.
I dont care really if it blows up ... it is more me not crashing if it happens

Are you using tire levers to install the tire? If so, maybe the lever damaged the tube.

Yeah, real hard to find holes since you can't put much pressure in them out of the tire. Some even have leaks in them out of the box. I bought a couple of Cyclami tubes to try or keep as a compact spare. They are so cheap, that they are probably not even worth the effort to patch. I like the metal valve stem, but the valve core isn't removeable.

Yes. I had a piece of wire puncture and I could only see the puncture underwater by bubbles.
Even after, it was invisible.

No all by hand. But maybe in this case removed the tire once I can't really remember to be honest. But to conclude I will even be more cautious then I already was

as I love the feel of latex.

Alright

Hello.

I am using the TPU from RideNow and in the purchases I make they send me the self-adhesive patches from Cyclami. I notice that over time they turn yellow and lose adhesion even if they are not used.

Has anyone tried the glue that is sold separately?

Weber, read my post about glue here:

Weber, read my post about glue here:
viewtopic.php?p=1852955#p1852955

The technical specs for TechnicQll Soft Plastic Glue say it is "temperature resistant" up to 80°C
The technical specs for Camplast glue say it is "stable" up to 60°C

Based on those specs, it doesn't seem like a good idea to use these glues to fix TPU tubes for rim brake rims.
Maybe for disc brake rims, but black rubber can get pretty hot under direct sunlight in summer.

[marsa]

Valid point. Still, it is interesting, that the Camplast is what is included in some "big brands" TPU repairt kits.

Tubolito and Pirelli for example.

[RimClencher]

Seems pretty irresponsible.

Been running Ridenows and couldn't be more satisfied. Need some more of them. Has anyone bought recently and has some purchase link to get the cheapest price?

[charirider]

I ride rim brake bikes, mainly in the mountains.
Rims are carbon of course.
Can I go with 24g tube, or 36g one will be safer?

[Steve Curtis]

Neither are recommended

I'm completely fine riding gen 1 ridenows and thinkrider tubes with rim brakes in the mountains. I would trust manufacturers when they say lighter ones are not compatible with rim, but the thicker ones are absolutely fine
