A thousand years ago when I got my first bike l learned from a book how to fix punctures and replace tyres. The bike I had back then had a basic three speed Sturmey Archer hub and removing a wheel was pretty easy. But as I said that was a thousand years ago. The only flat tyre I have had on the Brompton was when I damaged the valve recently. If I do any real damage to this bike I can just fold it up and take it where I need to get to and put it into the boot of the car and take it to Compton Cycles for any repair.
I am now more lazy. I keep putting off booking a place on the cycle maintenance class that runs on a Tuesday evening in my area. I now have the Trek and it will be easier to learn to change the tyre and do a repair myself than walk around London with a flat.
In the meantime I keep up, when I remember, with the bare minimum for bike maintenance. Keep the tyres at the optimum pressure. This stops unnecessary tyre wear as well as keeps you speeding along. I learned the hard way that you work twice as hard with a poorly inflated tyre. I also learned that I don't have the strength to pump a tyre with a hand pump and I think they are only designed to re inflate a tyre to get you home after a puncture repair. The one I got with Brompton got twisted up in the spokes when it slipped off and I haven’t bothered to replace it.
My new standing pump does the job but is more effort than my foot pump. I feel as if I’ve been working out in the gym every time I use it.
