Marv’s Law of Bicycle Punctures….Revisited



Dear Roulers,

I had intended to write a wrap up of the Giro 2015 and list of where all the surviving Australians placed.  I will digress briefly to contgratulate Luke Durbridge for his second place in Stage 21.  However, this blog is about the new clause I’m adding to my eponymous law of bicycle punctures.  For the record this is second one in 3 weeks.  Its winter, its wet and there is all sorts of crap on the roads at the moment, so therefore its not unexpected.

So this morning I’m keen to do a medium paced, for me at least, 30km. The conditions are cold, wet and windless, in other words perfect for an early morning ride. I set off slowly, I’m still getting used to the SPD-SL clip in-action.  They are super-slippery in wet conditions.  I arrive at the second most irritating traffic lights in Port Melbourne, on the corner of Beaconsfield Parade and Pickles St, when I notice that horrible ride feeling of quickly deflated rear tyre…..sigh.

I’m still a bit sleepy and still warming up.  Consequently I’m mildly annoyed, however as I said before, its not unexpected. After a fit of the fumbles I managed to swap the inner tube over.  I start pumping air into the tyre when I realise …horror… nothing is happening.  I recheck the pump and its seal on the valve.  Then I realise that my new replacement tube has a faulty valve and that I do not have another spare or a repair kit.  Now I’m cold and really irritated.  I trudge back 1.5km back to my house, no doubt mangling the SPD-SL cleats.  I have no choice.  Its this or bare foot which on a wet, cold morning was unthinkable.

So lets go back to the law:

Clause (i) If you are going to get a puncture, it will be at most inconvenient time – Tick -> early morning was very irritating.

Clause (ii) It is inevitable that you will have more punctures on your back wheel – Tick -> back wheel it was.

Clause (iii) It more likely that you will have rear puncture when you haven’t cleaned your rear running gear and/or are wearing new clothing – Cross -> I had just cleaned by gears and I didn’t have new clothing on.

Clause (iv) It is more likely that you will get a puncture when it rains – Tick -> Yep it had rained heavily overnight.

Clause (v) It is more likely that you will get a puncture and then have the weather turn bad with heavy showers making your machine’s parts that much harder to handle. Tick -> It was wet and cold.

Clause (vi) It is more likely that you will get a puncture when you are riding alone when there is no one to help you. Tick -> Yep, I was alone.

Clause (vii) It is more likely that you will get a puncture, if you are stupid enough to boast about never getting one.  Cross -> Nope, I never thought this or said it out loud.

Not bad validation so far, now for another clause,

Clause (viii) It is more likely that you will get a puncture when you have a dud spare, for example one with a faulty valve and no other way of fixing the puncture. Tick -> Yep, this was very F%&#king irritating.

Until next time,
