Track Pump kills my wheel
So this is my track pump. A sound investment that eliminates hours of painful handing pumping each year. Four or five depressions of the top handle will get most tyres up to 60 PSI.
So I had to get a replacement inner tube this weekend. I didn’t quite know the size so the guy in the shop gave me the best fit he could from a rim measurement but not much else. It was a pretty tight fit to get the tube over the rim (Hmmm should have paid attention to that) but I’ve had this before with new inner tubes before. I had got new tyres the week before so I thought, new tyres, new tubes, lets take it up to 80 PSI. I normally inflate to 75 PSI but the tyres and tubes were rated to 100 PSI.
Well we got to around 70 PSI pretty fast and everything was hunky dory. I squeezed the tyre and it didn’t seem particularily drum tight. So I hit the pump are a few more times and KABOOM!
When my ear drums recovered I was looking at this,
Well the inner tube was shredded by a rip about a foot long and that long white bendy piece in the picture, well thats the rim of the wheel.
Lets just say, I’m gonna be a bit more respectful of the power of the track pump in future.
