Actually I though of this tonight while mowing the lawn and thought I'd share......to illustrate my tyre-changing prowess.
Before leaving for Lorne & the AGF Gran Fondo, I'd noticed a sizable gash in my rear tyre. Figured I'd swap the tyre over here in the garage rather than have to deal with a puncture or worse during the weekend away.
Set down to business. Grabbed new tyre from the spares cupboard. Wheel off, old tyre off, tube re-used, fitted new tyre after much straining and cursing. Damn, these GP4000s tyres (when new) are a tight fit on a Velocity A23 rim.
Just as I finish levering the last of the tyre bead on, I notice I've pinched the tube. !@#$%. Tyre off. Tube out. Grab tube #2. Repeat process. Literally identical. !@#$%. Grab tube #3. Repeat process. You guessed it. !@#$%. Grab tube #4. WIN!!! Pump tyre up to pressure, all seems well. Finished.
2 days later, arrive in Lorne. Wife & I attempt to ride out on Saturday morning down to Wye River for breakfast. Jump on the bikes from our holiday house, ride about 500 metres.......just into the main street of Lorne......FARKIN BANG!!!!! Yep......tube was pinched when I installed it.
By now at least the tyre had been stretched & softened somewhat, and the roadside tube change was completed (without mishap) in about 10 minutes.
Don't know that I'd get a job changing bicycle tyres.
And I'm thankful I bought that carton of 30 Continental tubes a little while ago......
