How To Change An Inner Tube Without Tyre Levers
Here's a clever little link from British Triathlon on how to change an inner tube without tyre levers! click here
Although I would like to see them do it on some of the childrens bike tyres as they are so tight on the rims it needs Hercules plus three tyre levers to remove!
There's other "How To's" after the first one so just keep watching!
