Magene TPU tubes minimum pressures

Equipment
1

Hey all, have recently purchased a new wheelset and have set these up with Magene TPU tubes reusing the Continental GP5000 S TR tyres 700 x 28. Didnt want to mess with setting up tubeless as im setting up new tyres in Feb before my A event.

End of this week im heading to the mountains for a few days training. Its forecast to rain so will be running lower pressues.

Question is how low can I go with the TPU tubes… there is nothing in the user manual for the tubes.

When on tubeless I ran 65psi but not sure I can go this low on TPU’s. Im 75kg if that helps.

Currently been running the TPUs on 80-85psi in dry weather.

Thanks in advance.

I run mine around 60 / 65 psi on chip sealed roads. GP5000S - 28’s. You have to be careful as with any tube. They will pinch flat if you hit an obstacle. In my case it’s cattle guards that have irregularities. If the roads here were smoother I would run them at a higher psi.

Been lucky so far… 700km riding on rough roads even hit some minor holes in the road on occasions ans ridden all sorts of different tarmac. Running fine at 85psi.

Guessing 65psi should be ok then.
