I've had a total nightmare with punctures in the last week or so of riding. As the problem was with new rims with new tape and new tyres, I've been constantly questioning myself as to what the cause has been.
All of the punctures look like thorn holes on the INSIDE of the tube along the same mold line in the rubber. This is consistent with all of the punctured tubes.
Anyway, I was beginning to think that there was a problem with my wheel but given that they are 50mm rims it couldn't be the spokes popping through.
I was just out for a 50 miler and after my fourth puncture (and running out of tubes and patches) I limped into a bike shop to ask them to take a look. Luckily, I had three knackered tubes on me for them to have a look at.
The mechanic was sure it wasn't anything to do with my wheel...he reckons everything is in order. The bike mechanic verdict was that my Bontrager 80mm long valve inners had been sitting unsold on a shelf for a long time and the rubber had perished.
This is also backed up by the fact that I only have had this problem with the same batch of Bontrager tubes bought from my LBS at the same time.
Has anybody else come across dodgy tubes before? Surely it must be the tubes if the same failure has happened to all of them multiple times and it is certainly not my wheel? Since fitting some new Schwalbe tubes, I have had no problems although I've only riden 25mi since doing so.
