I can go a year or two without a flat and then have a run of them on different wheels and different bikes. Usually at times when I'm running late and it's raining.
This thread makes me feel superstitious, though. I don't know why I even offered an answer. I'll let you know if I get a flat this week and will definitely blame my participating in this thread as the culprit.
Since taking up cycling again in November last year (after a very long break) I've ridden over 2500km mostly commuting on both a mountain bike and a road bike, but in the last 4 months or so riding 60-70km on weekends. The amazing part is that in all this time I've only had 1 flat tyre and that was when I first started out on my mountain bike. Since getting my road bike I've done about 2000km had no flat. This does seem quite low, especially for London roads... Back in the day I remember getting a flat at least every 500km or so...maybe my luck has changed.
I think I might be tempting fate by posting this, but I am touching wood.
On average, how often do you get a flat?
Almost 1400km here since Istarted riding seriously in Feb/Mar 2006 on a brand new bike that we bought but ended up buried in the basement for 10yrs. Only flat I had was a pinch flat I think because it was in storage all these years and never used. I used a cheap flat repair kit and since then have put almost 1400 km to date.
I think I got some IRC fat knobbie tire and pobably some IRC tubes I think. Everything is pretty much stock from the bike store. I still carry a spare tube just incase seeing how I broke the 1000km mark a while ago and the bike shop last week said my stock chain still has lots of life left on it but I'd rather carry extras then get stuck out 50km out in the zone without a LBS around or worst, stuck in the bad areas.
I'd definately stick some self sealing tubes if I get my tire non-repairable flat and change the tires when they're worn out to punchture resistant tires and back it up with some puncture resistant liner tape so if you had to go Mad Max you know your tires will carry you home.
My other bike so far has only had one flat and that was a pinch. So far nothing els ei swrong so I'm happy. I probably would guess I get 0-1 flat a year.
