Before i drill a second valve hole , has anyone used 2 tubes in the rear tyre/tire? im thinking 2 light weight tubes which will be lighter than a heavy duty tube filled with sealant , i am a cheap arse so it will be a cheap thing to do . Not really sure about the pressures eg 2x10psi=20psi or 2x20psi=20psi????
Question 2.5

You put sealant in the tube? 😮 Why?🤔

No , you can buy them, the thick tubes with green sealant in them , i think they are called "thorn proof tubes" Repco brand..

Slime Tube?! Sounds like „with belt and suspenders“, as we say in Germany, and now you want to replace suspenders by another belt.

Question 2.7

How many puntctures have you had in, lets say, a month?

Subquestion 2.7.1

What was the main cause?

In the UK we say belt and braces. For men of a certain age here… suspenders means something completely different.

Subquestion 2.7.1

What was the main cause?
Pinch flats on rocks, could be one a week to one every few months , other advantages are less rolling resistance , less ballooning of the tube/tubes , more balanced wheel , in the event of puncture one tube hold air, low cost etc etc. No more sub questions.....
