I had a puncture on my R80 Basic a few weeks ago...Tubes fitted in tube type tyre...Do you think i could get the bead to break ...Some makes come off with a struggle with tyre leavers or by walking on them with your heels....If you got another bike you can use the side stand...But some of the stiffer side wall types wont budge....Thinking to myself if this happened on the trail i would have been in trouble ...So i made this...Mini maglight is there for scale
