One of my neighbours asked me to repair a puncture in her Grandsons bike. A BMX that was fairly new and in surprisingly good condition. But the tube has had it. SO---down to the LBs for a new tube. They asked if I wanted a Thornproof tube. Not thinking I said yes and instead of a normal sized box- they came out with this box that lookes as though it would have 10 tubes inside. Yep--- thats right- only one tube. It weighed as much as my Ultegra Front wheel with the tyre fitted.
Got home and boy is that tube thick. Thornproof?--I reckon that it might even withstand one of your famed Goatheads---Although I know nothing will stop a Goathead. The wall of this tube- according to the box- is 2.5mm thick. That is more rubber than I have on the tread part of my Michelin PR3's.
Fitted the tube and sent the lad on his way. 2 hours later and he was back- The tyre is flat. These tyres may be Thornproof but they most definitely are not Kerb proof. I put 40psi in the tyre- max as on the sidewall- but there it is---one snakebite. Managed to repair it and it stayed up but I think a few lessons in how to ride a bike is going to be in order. Either that or solid tyres.
How long was I in the army? Five foot seven.
