Just pulled them apart to re-fit my Schwalbes for now.
Deffo pinching. Slit in the tube in line with the rim.
The fact that I’ve had front and rear suggests not a rougue spoke or burr on the rim, and the rears have been in different places. But will check again as I’d ruled that out so not checked.
Tubes are a variety of brands, the last two were 25/32mm and 28/32mm. I had to limp to the Triathlon shop in Nottm to get an emergency tube to make sure I got home on Tuesday. They only had race ones at £9 each! When i had to fit it 5 miles from home it seemed the best £9 I’d ever spent. At least that is now a spare for the tri bike.
As I said, same rims with bigger tyres and no punctures in the last couple of years (except for when a sidewall ripped on an old tyre, but that was another story).
And yep, I remember distinctly hitting that stone and the resultant sinking feeling.
I do batter over stuff, fully laden, but it just seems to be this tyre/rim combo. Didn’t suffer with the previous tyres until they perished with age and split the sidewalls!
Hmmmmm……I could try some (more) different tyres I guess. Keep the GP4Ss for winter road training use.
Maybe a 28 or 32? Any suggestions?
