TPU inner tubes

[Tommohawk]

I am looking to upgrade my butyl inner tubes to TPU tubes for my Giant Contend SL1 disc. I upgraded the wheelset to some VEL alloys and the tyres to Continental GP5000 a couple of years ago and this has made a noticeable difference already. Is Temu safe to use to buy the RideOn ones? The price seems ridiculously low. Thanks in advance.

If going for the Ride Now ones try to get the ones with the metal valves. Cyclami from Ali Express are also good. Again there are different versions. Go for the slightly heavier ones with metal valves.

The 36g ones?

I’m running 28mm tyres and I just watched a video on YouTube by Reginald Scott suggesting that they are not the best for “wider” tyres due to having to stretch.

I'm running them on two bikes, one with 30mm tyres and one with 28mm. No issues so far. Think the ones I have are rated for up to 32mm tyres.

Just took the plunge and ordered 4 x Ridenow TPU inner tubes.

4 for price of 3 ~£51, officially can be injected with Oko or Muc Off sealant, might get around to ordering some now the gravel version back in stock. Has a funcky valve cap with integrated valve core tool!

Is about 75psi okay to run the tubes for 28mm tyres? My track pump doesn't seem to want to go much higher than that.

Depends heavily on the weight of you riding the bike and to a lesser extent, the type of bike (as this will affect how much of total weight will be effectively on the rear wheel).

Also, don't take the width as labelled on the tyre as gospel, give it a quick measure yourself. Will be affected by inner rim width of wheels you are using and whether manufacturer is "lying" or not.

I'd question the quality of your track pump, or the accuracy of your pressure gauge.

It's a topeak joeblow sprint (I think). It's a Giant Contend sl1 disc.
