Cycling in Sydney Australia
I have. It happens. I cannot remember the cause.
Bill it was a mega bad day.
There are some things that get through but very very few.
Yes, I have punctured my SMPs three times. Twice it was a building tack, and the third it was a large piece of glass with a needle like point on it.
I should point out, however, that 3 punctures in 4 years is not bad! My current set of SMPs, according to BikeJournal:-
700 x 28C Schwalbe Marathon Plus, front, 9,338 km (no punctures)
700 x 28C Schwalbe Marathon Plus, rear, 8,274 km (1 puncture)
Only once. Rainy night, very sharp piece of glass, tyre pretty worn down - though not yet down to the blue kevlar.
sorry to hear about the bad day...just make sure you go out and have a good one tomorrow.
and in answer to the question. yes
large piece of glass, conical shape.
I had seen the glass and opted to ride through it as the other option was to swerve into the path of bus just behind me. I thought at the time will have to check that when i stop...then didn't
half way up the first hill on my journey home that afternoon it got pushed it through the blue stuff. I'd probably ridden about 20k's with it wedged into the wheel before it got through to the tube. If i'd checked the tyres when i got to work like i thought i should, i would've been ok.
That looks like a teensy-weensy little samurai sword!
Now why would a teensy-weensy little samurai leave that lying around on the road??
Long slivers of wet glass. Also the years old tyre pushing a broken bead through its own side wall. I'm okay with this.
They are about as puncture 'resistant' as you can get but that doesn't mean they're puncture proof (I'm not aware of any pneumatic bike tyres that are, actually) and if you're going to get a puncture with them, it is going to be from something long & sharp. Sounds like you just had a dreadful day.
I hope today was better!
